Japan's Diet passed the Foreign Exchange and Foreign Trade Act (FEFTA) 2026 Amendment on 29 May 2026; the law was promulgated on 5 June 2026. The amendment represents the most significant overhaul of Japan's inbound FDI screening regime since FEFTA was first applied to national-security transactions in 2019. Three structural additions: (1) indirect-acquisition screening — extends mandatory prior-notification to acquisitions of Japanese sensitive-sector companies effected through intermediate holding structures or offshore parent vehicles, closing the principal gap exploited by Chinese and GCC SWF investors via SPV chains; (2) call-in powers — grants the Minister of Finance authority to open a review up to ten years retroactively where an acquisition was not pre-notified or where circumstances have materially changed since clearance, directly analogous to CFIUS § 721(b)(1)(D) retroactive jurisdiction; (3) cross-ministerial "Japan CFIUS" consultation framework — formally institutionalises a standing inter-agency committee (Finance, METI, MoD, NPA, MIAC) modelled on the US CFIUS committee, replacing the prior ad-hoc inter-ministerial process. Cross-ministerial and indirect-acquisition provisions entered into force immediately on promulgation (5 June 2026); remaining Cabinet-Order-level implementing provisions to follow within one year.

On 15 April 2026 Japan's Ministry of Economy, Trade and Industry (METI) published the interim summary "Manufacturing Base Strengthening Report" from the Study Group on Strengthening Manufacturing Base in Light of Geopolitical Risks. The report frames Japan's manufacturing base as the source of national power and proposes shifting economic-security support for "autonomy assurance" from "point" measures to "area"-wide measures — expanding the scope of Specified Critical Materials under the 2022 Economic Security Promotion Act (ESPA) beyond narrowly defined inputs to cover foundational petrochemicals (ethylene, propylene, methanol, synthetic rubber) and process-industry technologies (casting, forging), plus components for emerging technologies (humanoid-robot actuators and sensors, lasers for quantum computing). It is the cornerstone framework document operationalising METI's FY2026 strategic-budget package (~¥3.07 trillion overall envelope; ~¥1.23 trillion specifically for semiconductors and AI, including ¥150bn for Rapidus and ¥387.3bn for AI development) as Japan's coordinated response to deepening Chinese export-control pressure on dual-use items, gallium/germanium, graphite, antimony and heavy rare earths.

On 1 April 2026, Prime Minister Takaichi Sanae and President Emmanuel Macron held a Tokyo summit and signed a bilateral roadmap on cooperation in critical minerals — the first formal Japan-France instrument on supply-chain resilience for rare earths and other critical materials. The centrepiece is joint government support for Caremag, a heavy rare-earths refining project in southern France due to begin operations in late 2026, with backing from Japan Organization for Metals and Energy Security (JOGMEC), Iwatani Corporation, and the French government; the project targets approximately 20% of Japan's future demand for dysprosium and terbium (heavy rare-earth oxides used in EV motors, offshore-wind turbines, and electronic components). The two leaders also launched parallel high-level dialogues on dual-use AI, quantum technologies, space (including debris mitigation), cybersecurity, and a joint declaration on startups and innovation, expressing "serious concerns" over export controls on critical minerals and other materials affecting global supply chains — an explicit reference to China's tightening rare-earths export regime.

On 20 March 2026, METI/MOFA (Japan) and the US Departments of State and Energy jointly published the "Japan–United States Critical Minerals Project Cooperation Joint Fact Sheet," identifying five specific upstream critical-mineral projects spanning four continents (Australia, Tanzania, Brazil, UAE, Namibia) to receive structured joint financing through JOGMEC equity and offtake instruments and US DFC/Ex-Im Bank facilities. The document operationalises the October 2025 US-Japan Critical Minerals Framework and the same-day Action Plan, converting policy-framework language into named project commitments covering nickel, lithium, battery-anode graphite, and heavy rare earths. It was released the day following the Takaichi–Trump summit on 19 March 2026 and follows the Critical Minerals Investment Ministerial convened in Tokyo on 14 March 2026.

NEDO, under METI's Green Innovation Fund, launched the "Next-Generation Tandem Solar Cell Mass Production Technology Demonstration Project," a JPY 153.3 billion (maximum; JPY 123.2 billion committed for the initial three-year phase) programme running fiscal 2025-2030. Two companies — Kaneka Corporation and Aisin Corp — were selected, each holding mass-production plans exceeding 500MW by fiscal 2030 for perovskite-silicon tandem solar cells. The programme targets conversion efficiency above 30% and a residential generation cost below JPY 12/kWh, aimed at establishing high-yield, high-throughput manufacturing processes ahead of anticipated global scale-up.

On 26 December 2025, Japan's Cabinet approved the FY2026 (Reiwa 8) national budget, which the Global Trade Alert database logs as including a "Multi-modal Foundation Model Development Project with a Focus on AI Robots and Physical AI" financial-grant line administered by METI, effective with the fiscal year on 1 April 2026. NEDO -- METI's implementing R&D agency -- operationalised this line through a commissioned-project (100%-funded) solicitation opened 24 March 2026 and closed 22 April 2026, capping funding at up to JPY 383.4 billion (~USD 2.5bn) per adopted proposal for FY2026, with the programme running FY2026 through FY2030 (initial contract period FY2026-FY2027, annual stage-gate reviews thereafter). The goal is a domestically developed multimodal ("VLM/VLA") foundation model that keeps Japanese factory-floor and robotics data onshore while underpinning "physical AI" -- AI systems embedded in robots and industrial equipment -- to address labour shortages and lift manufacturing productivity. NEDO's call for proposals subsequently selected Noetra Inc. and the National Institute of Advanced Industrial Science and Technology (AIST/産総研) as awardees.

On 26 December 2025, Japan's Cabinet approved the FY2026 (Reiwa 8) initial budget, which allocates a new JPY 415 billion (~USD 2.7bn) line to the "Low-Carbon Hydrogen Hub Development Support Project" (低炭素水素 等拠点整備支援事業), administered by METI's Agency for Natural Resources and Energy (ANRE) through JOGMEC under the Hydrogen Society Promotion Act framework enacted in 2024. The programme subsidises Front-End Engineering Design (FEED) and construction costs for shared transport and storage infrastructure -- tanks, pipelines and receiving-terminal equipment -- built jointly by multiple businesses to move low-carbon hydrogen and its derivatives (ammonia, e-methane, synthetic fuels) from import/production points to industrial users. It sits alongside, but is administratively distinct from, JOGMEC's separately-run "price-gap" (kakakusa) 15-year CfD offtake support for hydrogen suppliers. The budget takes effect with Japan's fiscal year on 1 April 2026, subject to ordinary Diet passage in early 2026.

On 26 December 2025, Japan's Cabinet approved the FY2026 (Reiwa 8) national budget, which allocates JPY 122.0 billion (~USD 800m) to the "Next-Generation Innovative Reactor Technology Development and Industrial Base Strengthening Support Project" (次世代革新炉の技術開発・産業基盤強化支援事業), up from JPY 88.9 billion in the FY2025 initial budget plus a JPY 6.0 billion FY2025 supplementary allocation. The programme, administered by ANRE under METI's GX (Green Transformation) Promotion budget, funds technology development and supply-chain build-out for Japan's "innovative light-water reactors" (revised BWR/PWR designs with enhanced passive safety) and small modular reactors under the government's GX2040 Vision. The budget takes effect with Japan's fiscal year on 1 April 2026, subject to ordinary Diet passage in early 2026.

On 26 December 2025, Japan's Cabinet under Prime Minister Sanae Takaichi approved the FY2026 (Reiwa 8) national budget, which allocates JPY 150 billion (~USD 1bn) to the "Investment Project for Mass Production of Next-Generation Semiconductors" -- a state equity-investment line administered by the Information-technology Promotion Agency (IPA) that funds Rapidus Corporation's 2nm-class logic fab in Chitose, Hokkaido. The FY2026 allocation is 50% larger than the JPY 100 billion IPA equity tranche budgeted for FY2025, taking cumulative government equity in Rapidus to roughly JPY 250 billion. The line sits inside METI's wider AI/semiconductor budget of JPY 1.239 trillion for FY2026 (up roughly 4x year-on-year) under the "AI/Semiconductor Industry Base Strengthening Frame," part of the government's pledge of over JPY 10 trillion in public support for AI and chips through FY2030. The budget takes effect with Japan's fiscal year on 1 April 2026, subject to ordinary Diet passage in early 2026.

Japan's Ministry of Land, Infrastructure, Transport and Tourism (MLIT) and the Cabinet Office jointly published the Shipbuilding Revival Roadmap (造船業再生ロードマップ) on 26 December 2025, redefining shipbuilding as a "national strategic industry" within an All-Japan shipping-and-shipbuilding framework. The Roadmap targets doubling domestic shipbuilding capacity from ~9 million GT to 18 million GT by 2035 (re-capturing roughly 20% global market share) backed by a ¥1 trillion (~USD 6.4 bn) public-private investment commitment over three staged phases (2026-28 automation, 2029-31 facility expansion, 2032-34 dock-operation support), mandates consolidation of domestic shipbuilders into 1-3 groups by 2028, and is funded in its first three years by a ¥120 bn FY2025 supplementary budget enacted in December 2025.

On 21 November 2025, METI Minister Yoji Akazawa designated Rapidus Corporation as the official next-generation semiconductor manufacturer under Japan's Act on Facilitation of Information Processing (情報処理の促進に関する法律, as amended by the Cabinet-approved partial-amendment bill of 7 February 2025), following a public solicitation run 3 September – 2 October 2025. The designation makes Rapidus eligible for a multi-year METI funding envelope reported at roughly JPY 1tn (~USD 6.4bn), with an initial JPY 100bn equity investment by the Information-technology Promotion Agency (IPA) planned for FY2025; the funds support Rapidus' Hokkaido (Chitose) IIM-1 fab targeting 2nm GAA mass production from April 2027 and successor 1.4nm / 1nm nodes. The action is the first standalone Rapidus entry in the IPTM register and operationalises the supply-chain pillar of the 2022 Economic Security Promotion Act for advanced logic.

Japan's Ministry of Economy, Trade and Industry amended the Export Trade Control Order (輸出貿易管理令) to add four technology categories to the prior-notification-of-transfer list under the Technology Management Scheme through Public-Private Dialogue (TMS-PPD): quantum-dot materials, TADF (thermally-activated delayed fluorescence) emissive materials, phase-difference film, and flexible endoscopes. Announced 11 November 2025, promulgated 19 November 2025, and effective 19 January 2026. This is the first list-control update produced by the TMS-PPD mechanism, which was established in December 2024 as an annual METI–industry review process for adding emerging-technology items to prior-notification controls outside the slower Wassenaar Arrangement / FEFTA catch-all channels.

Japan's Cabinet adopted a Cabinet Order on 11 November 2025 (promulgated 14 November 2025, effective 14 February 2026) amending Appended Table 1 of the Export Trade Control Order (輸出貿易管理令) to add three new list-control item categories: (i) peptide synthesizers and related components (Item group mapping to Australia Group 2023–2024 plenary dual-use biotechnology controls, aligning Japan with the US BIS implementation promulgated December 2024), (ii) powders of refractory metals or their alloys below specified particle-size and purity thresholds — tungsten, molybdenum, niobium, tantalum, and rhenium powders used as additive- manufacturing feedstocks (Item 5(20), implementing a Wassenaar Arrangement plenary outcome on metal-powder dual-use), and (iii) modules, assemblies, or devices incorporating field-programmable logic devices (FPGAs) above specified gate-count and process-node thresholds (Item 7(10-2), extending Japan's semiconductor-component AI-compute perimeter). This is the first discrete Appended Table 1 list-control amendment filed under the post-October-2025 FEFTA catch-all- controls overhaul architecture.

On 31 October 2025, Japan Investment Corporation (JIC) and its subsidiary JIC Capital, Ltd. (JICC) announced the establishment of two new private-equity limited partnerships — JIC PEF2 (JPY600 billion) and JIC PEFJ2 (JPY200 billion), collectively "JIC PE2" and totalling approximately JPY800 billion (~USD 5.36 billion) — launching 1 November 2025. The funds provide state-backed risk capital for large-scale industry restructuring, growth investment, and business-restructuring deals in capital-intensive sectors (mobility, semiconductors, chemicals, materials, healthcare) where JIC judges private PE capital in Japan to be insufficient. PEF2 is the main investment vehicle (10-year term, 5-year investment period); PEFJ2 co-invests alongside PEF2 in large-scale projects.

Japan's Ministry of Economy, Trade and Industry (METI) revised its Foreign End-User List (外国ユーザーリスト) — the reference list of foreign organisations for which WMD/missile or, for the first time, conventional-weapons development concerns cannot be excluded, used to trigger catch-all export-licence requirements. The revision adds 92 entities (from China, Hong Kong, North Korea, Russia, Pakistan, Iran and the UAE) and removes 5 entities (from China, Iran and India), taking the list to 835 entities across 15 countries and regions — a net increase of 87. The revised list applies from 9 October 2025, the same date Japan's broader catch-all conventional-weapons supplementary export-control review took effect.

On 26 September 2025, Japan's Minister of Finance Katsunobu Kato announced the establishment of the Japan Strategic Investment Facility, a JBIC-administered financing vehicle operationalising the USD 550bn investment pledge from the July 2025 US-Japan tariff and investment agreement. The facility launched 1 October 2025 and runs through March 2029, supporting the overseas expansion of Japanese companies across nine economic-security sectors: semiconductors, pharmaceuticals, steel, shipbuilding, critical minerals, aviation, energy, automobiles, and AI/quantum technology. Funding draws on three sources — dollar-denominated JBIC bonds, yen-denominated Japanese government loans to JBIC, and a "supplemental" transfer from Japan's USD 1.324tn foreign-currency reserves — with private-sector loans and NEXI-backed loan guarantees supplementing JBIC's own financing.

Japan's state-owned Development Bank of Japan (DBJ) announced on 2025-09-18 that it executed "hybrid finance" — a subordinated-debt instrument treated as partly equity by rating agencies — in support of Nippon Steel Corporation's acquisition of United States Steel Corporation. DBJ's participation formed part of a JPY 500 billion (~USD 3.4bn) committed subordinated term-loan facility, syndicated alongside Japan's three megabanks (MUFG, SMFG, Mizuho) and Sumitomo Mitsui Trust, that Nippon Steel closed the same day to repay short-term bridge loans used to fund the consideration for its USD 14.9bn acquisition of US Steel. DBJ extended the financing under its "Specific Investment Operations" (特定投資業務) program, which is reserved for deals it deems to strengthen the international competitiveness of Japanese industry.

Japan lowered its price cap on Russian-origin crude oil from USD 60 to USD 47.60 per barrel, effective for contracts concluded on or after 12 September 2025, aligning with the EU's July 2025 cut under its 18th sanctions package. The measure bars Japanese entities from importing, or providing shipping, insurance, financing or other services for, Russian crude priced above the new cap. In the same package Japan added 47 Russian entities and 9 individuals, 6 Crimea/Donbas-linked persons and entities, and 3 third-country entities to its asset-freeze list (transactions now require Ministry of Finance approval), and imposed export prohibitions on 2 Russian entities and 9 entities in third countries. Japan's own Russian crude imports are minimal (~0.1% of total crude imports, Jan-Jul 2025), so the measure is primarily a coalition-alignment and shipping/insurance-chokepoint action rather than a material change to Japan's own energy sourcing.

Japan Bank for International Cooperation (JBIC) signed a loan agreement on 2025-06-30 for up to approximately USD 626 million (JBIC portion) with Mitsui & Co., Ltd. Co-financed with Sumitomo Mitsui Banking Corporation, the total co-financing package reaches approximately USD 1,044 million. Proceeds fund Mitsui's investment in Blue Point Number One, LLC, a low-carbon ammonia production facility under construction in Louisiana using CCS technology to cut over 95% of process CO2 emissions. JBIC frames the loan against Japan's Basic Hydrogen Strategy, Seventh Strategic Energy Plan, and GX2040 Vision, which treat hydrogen and its derivatives as key decarbonization energy sources requiring policy-bank-mobilized capital.

Japan's first standalone AI statute (Law No. 53) was promulgated 4 June 2025 and became fully effective 1 September 2025, when chapters establishing the Artificial Intelligence Strategic Headquarters — chaired by the Prime Minister with all Cabinet ministers as members — entered into force. The Act adopts an innovation-first, non-punitive framework: it imposes no monetary penalties and relies on cooperative and reputational compliance mechanisms rather than mandatory requirements. An AI Basic Plan, adopted by Cabinet decision on 23 December 2025, translates the statutory mandate into cross-ministry R&D and deployment targets.

Japan's National Diet passed a partial amendment to the Pharmaceutical and Medical Device Act (PMD Act / 薬機法) on May 14, 2025, promulgated as Law No. 37 of 2025 on May 21. The amendment requires every Marketing Authorization Holder (MAH) to designate a Supply System Manager responsible for reporting supply disruptions to MHLW, and grants MHLW authority to order replacement of key quality personnel when systemic deficiencies are found. It also reforms GMP oversight to a risk-based inspection model and expands the conditional-approval pathway for rare disease and paediatric drugs. Enforcement is staggered across three tranches: November 2025, May 2026, and final full implementation by May 2027.

Japan's Ministry of Economy, Trade and Industry (METI) overhauled the catch-all export-control framework under the Foreign Exchange and Foreign Trade Act (FEFTA) — the first comprehensive review of Japan's catch-all controls in 12 years (since 2013). Cabinet decisions were taken on 25 March 2025 and 4 April 2025 with METI's consolidated announcement on 9 April 2025; the amended Cabinet Order entered into force on 9 October 2025. The reform (i) splits catch-all-controlled items into "core items" (high dual-use risk, including certain semiconductors and machine tools) and a general catch-all tier, (ii) adds a new end-user requirement alongside the existing end-use requirement and extends both from UN-arms-embargo countries only to "general countries" (everywhere outside Group A), materially expanding the perimeter of items requiring METI export licences for general-country end-users including China, and (iii) introduces an "informed" condition for exports to Group A countries — once METI notifies an exporter of a defined risk pattern, a Group A export becomes licence-required, addressing transit-export-circumvention to Russia. Structurally distinct from the 23-category equipment-specific 2023 amendment (2023-03-31-japan-meti-semi-equipment-export-controls); this is the underlying horizontal catch-all reform and brings Japan's framework closer to US BIS EAR catch-all controls.

Japan's Cabinet approved an amendment to the Cabinet Order on Inward Direct Investment under the Foreign Exchange and Foreign Trade Act (FEFTA) on 1 April 2025; the order was promulgated 4 April 2025 and entered into force 19 May 2025. The amendment introduces two new investor categories — Type-A (investors legally or contractually obligated to share information with foreign governments) and Type-B (investors effectively in a comparable position without formal legal obligation) — and eliminates or narrows exemptions from mandatory prior-notification screening for both categories. The primary driver is concern over minority-stake acquisitions by Chinese investors in Japanese listed companies operating in sensitive sectors including cloud computing, telecommunications infrastructure, semiconductor equipment, and advanced electronics. The reform is structurally distinct from the outbound FEFTA catch-all controls overhaul (2025-10-09) and from the Economic Security Promotion Act (2022-05-18); it is the inbound FDI-screening complement to that framework.

Japan's National Diet enacted the Cyber Response Capability Enhancement Act (重要電子計算機に対する不正な行為による被害の防止に関する法律, Law No. 42 of 2025) on 16 May 2025, together with companion arrangement legislation. Commonly known as the Active Cyber Defense (ACD) Law, the statute authorises (i) government monitoring of foreign-origin internet traffic transiting designated Japanese communication infrastructure for national-security threat indicators, (ii) pre-emptive access and neutralisation operations against attacker infrastructure abroad by the National Police Agency and the Self-Defense Forces under unified command, and (iii) mandatory cyber-incident reporting and government cooperation duties on critical-infrastructure operators. Implementation is phased through November 2027, with the NISC reorganised into the National Cybersecurity Office (NCO) under the Cabinet Secretariat from July 2025.

The Diet enacted on 31 May 2024 (promulgated 7 June 2024 as Law No. 45 of 2024) the "Act on Partially Amending the Act on Strengthening Industrial Competitiveness and Other Acts to Create New Business and Encourage Investment in Industries". The provisions establishing Japan's first US IRA-style production-and-sales-linked tax credit took effect 2 September 2024 per METI's press release of the same date. Eligible enterprises with a METI-certified business plan can claim tax deductions tied to domestic production-and-sales volume of five designated strategic products: electric vehicles, green steel, green chemicals, sustainable aviation fuel (SAF), and semiconductors. The credit is available for ten years from certification (certifications must be issued by 31 March 2027), with an annual cap of 40% of corporate tax liability (20% for semiconductors) and a 4-year carry-forward. Eligibility is conditional on meeting wage-growth or capital-investment thresholds in each fiscal year.

Japan's Act on the Promotion of Supply and Utilization of Low-Carbon Hydrogen and its Derivatives for a Smooth Transition to a Decarbonized, Growth-Oriented Economic Structure (the Hydrogen Society Promotion Act) was enacted by the Diet on 17 May 2024, promulgated 24 May 2024, and came into force on 23 October 2024. It is Japan's first legislation specifically targeting hydrogen. The Act establishes a 15-year price-gap Contract-for-Difference (CfD) subsidy backstopping the delivered cost of certified low-carbon hydrogen, ammonia, synthetic methane and synthetic fuels supplied to Japan, plus a "Hub Support" capex grant for shared port/pipeline/storage infrastructure. METI is the competent authority and JOGMEC the implementing agency. Total subsidy envelope is ~3 trillion yen (~USD 20bn) financed via GX Transition Bonds under the 2023 GX Promotion Act.

Japan's National Diet enacted the Act on the Protection and Use of Critical Economic Security Information (重要経済安保情報の保護及び活用に関する法律, Act No. 27 of 2024) on 10 May 2024; it was promulgated on 17 May 2024 and came into full operation on 16 May 2025. The law establishes Japan's first peace-time economic-security clearance regime extending to private-sector employees. It designates "Critical Economic Security Information" (CESI) covering threat-intelligence on critical-infrastructure cyber attacks, regulatory-review information on essential infrastructure, and vulnerability data on critical-product supply chains; mandates Cabinet Office "適性評価" (suitability assessment) for cleared personnel; and imposes criminal penalties of up to five years' imprisonment for unauthorised disclosure. The CESI Act complements the 2022 Economic Security Promotion Act (ESPA), closing the information-protection gap and aligning Japan's framework with Five Eyes and EU partners for joint R&D and dual-use cooperation.

On 5 April 2024 Japan's Cabinet adopted an amendment to the Export Trade Control Order, following a 1 March 2024 Cabinet understanding, extending the export prohibition on goods that strengthen Russia's industrial base. The additional goods span parts of HS chapters 27 (mineral fuels and oils), 28 (inorganic chemicals), 39, 73, 81 (tungsten powder, molybdenum, cobalt, zirconium, rhenium), 82, 84, 85 (including lithium-ion and nickel-metal-hydride batteries), 89 and 90, with the specific goods fixed by ministerial ordinance and notices issued on 10 April. The export ban applies from 17 April 2024. A separate METI notice bans imports of non-industrial diamonds of Russian origin from 10 May 2024, regardless of port of shipment.

On 28 March 2024 the Cabinet Office Committee on National Space Policy adopted Japan's Space Technology Strategy, the country's first national space-industrial roadmap establishing priority technology areas (space transportation, satellites, space science and exploration, shared technologies) and the operating framework for the ¥1 trillion (≈USD 6.4 billion) ten-year Space Strategy Fund jointly managed by JAXA on behalf of METI, MEXT and the Cabinet Office. The Strategy sets headline targets of doubling Japan's space-industry market to ¥8 trillion by the early 2030s and reaching ≈30 launches per year. A METI/MEXT/CAO Basic Policy of 26 April 2024 operationalised the Fund's grant architecture, and JAXA opened the first calls in July 2024. The Strategy is the parent authority for subsequent JAXA Space Strategy Fund grant programmes and is Japan's structural counterpart to the EU Space Act (2025) and US National Space Policy.

METI committed up to 732 billion yen (~US$4.86 billion) in direct subsidies for Japan Advanced Semiconductor Manufacturing K.K. (JASM) to build a second wafer fab adjacent to the first JASM facility in Kikuyo, Kumamoto Prefecture. Confirmed by METI Minister Ken Saito at the Fab 1 opening ceremony on 24 February 2024, two weeks after TSMC, Sony Semiconductor Solutions, Denso, and Toyota jointly announced the Fab 2 expansion (6 February 2024). Fab 2 will produce 6/7nm and 40nm logic for automotive, industrial, consumer, and HPC end-markets, with combined Fab 1 + Fab 2 capacity exceeding 100,000 12-inch wafers per month. Construction targets year-end 2024; operations target year-end 2027. Combined with the 476 billion yen Fab 1 grant, total JASM subsidies reach ~1.208 trillion yen, the largest single direct manufacturing subsidy in Japanese history. METI conditions require >=10 years of post-startup production and >=50% Japanese-domestic procurement of silicon wafers, materials, and components.

The Act on Promotion of a Smooth Transition to a Decarbonized Growth-Oriented Economic Structure (Law No. 46 of 2023), passed by the Diet on 12 May 2023 and promulgated 19 May 2023, establishes Japan's Green Transformation (GX) financing and carbon pricing framework. The government will issue 20 trillion yen in GX Economy Transition Bonds (the world's first sovereign transition bonds) to catalyze 150 trillion yen of public-private decarbonization investment over ten years (2023-2032). Bonds are repaid through a two-pillar carbon pricing system: a GX Emissions Trading Scheme (GX-ETS) launching voluntarily in FY2023, becoming mandatory for emitters >100,000 tCO2/year from FY2026; and a GX-surcharge on fossil fuel importers phased in from FY2028.

Japan's Ministry of Economy, Trade and Industry (METI) announced on 31 March 2023 amendments to the Foreign Exchange and Foreign Trade Act adding 23 categories of advanced semiconductor manufacturing equipment to the export-licensing list. The measure, effective from 23 July 2023, is the Japanese counterpart to the US October 2022 BIS rule (filed: 2022-10-07-us-bis-advanced-ai-chip-controls-china) and the Dutch DUV controls. Items covered span lithography (mostly ArF and KrF), deposition (CVD, ALD, sputtering), etch, and cleaning + advanced inspection — broadly the toolset used at ≤14/16nm logic, advanced DRAM, and advanced 3D NAND. The controls are formally non-discriminatory but in practice capture exports to China; non-China destinations get general licences.

The Act on the Promotion of Ensuring National Security through Integrated Implementation of Economic Measures (Law No. 43 of 2022), enacted 18 May 2022, establishes a four-pillar framework: (1) supply-chain resilience for "specified critical products," (2) security of critical infrastructure, (3) state-backed development of "specified critical technologies," and (4) non-disclosure of nationally sensitive patents. A December 2022 Cabinet Order designated 11 product categories as specified critical products, including semiconductors, storage batteries, permanent magnets, cloud programs, LNG, critical minerals, machine tools, and aircraft parts. Competent ministries must publish stable-supply plans, can fund private-sector surveys, and may provide subsidies to qualifying firms.

METI committed 476 billion yen (~$3.3bn) in direct subsidies covering approximately half the construction cost of Japan Advanced Semiconductor Manufacturing K.K. (JASM), a purpose-built joint venture fab at Kikuyo Town, Kumamoto Prefecture. JASM shareholders are TSMC (86.5%), Sony Semiconductor Solutions (6%), Denso (6%), and Toyota Motor (1.5 %). The fab manufactures 12nm, 16nm, 22nm, and 28nm mature-node chips targeting automotive-grade, industrial, and IoT applications. A groundbreaking ceremony was held on 13 April 2022; the facility officially opened on 24 February 2024 and reached commercial production in December 2024. JASM represents Japan's first new leading-edge wafer fab in decades and the largest single foreign direct investment in Japanese manufacturing history.

On 1 March 2022 Japan's Foreign Minister announced a second package of sanctions over Russia's military action in Ukraine. It suspended visas for and froze assets of designated Russia-related individuals and entities, froze the assets of three Russian banks (VEB.RF, Promsvyazbank, Bank Rossiya), and imposed export restrictions on Russian military-related entities and on controlled items on internationally agreed lists and other dual-use goods such as semiconductors. Relevant ministries were to proceed with the domestic implementing procedures.

On 24 February 2022 Japan's Foreign Minister announced sanctions following Russia's recognition of the "Donetsk People's Republic" and "Luhansk People's Republic". Japan suspended visa issuance to and froze assets in Japan of individuals of the two "Republics", prohibited imports from and exports to the two regions, and prohibited the issuance of and transactions in new Russian sovereign debt in primary and secondary markets. The relevant ministries were to proceed with the domestic procedures needed to implement them.

On 5 October 2021, Japan's Ministry of Economy, Trade and Industry, jointly with the Ministry of Finance, MEXT and MLIT, published amendments to the Regulatory Notices under the Foreign Exchange and Foreign Trade Act (FEFTA) adding two new categories to the "Core Business Sectors" subject to mandatory prior-notification FDI screening: metal mining (including mineral exploration vessels and land/underwater survey activity) and manufacturing, repair/maintenance or software for equipment used in metal mining (exploration vessels, marine equipment, excavators, drilling machines). The stated purpose is to secure the stable supply of critical mineral resources including rare earths. The amendment took effect 4 November 2021 after a 30-day transitional period; any inward direct investment of 1% or more in a covered business now requires case-by-case government pre-approval.

Japan's Foreign Exchange and Foreign Trade Act (FEFTA, Act No. 228 of 1 December 1949; 外国為替及び外国貿易法) is the foundational umbrella statute governing the entire modern Japanese economic-statecraft toolkit. Originally a restrictive positive-list regime for foreign-exchange transactions, FEFTA was fundamentally liberalised by the 1980 revision (positive-list to negative-list shift) and again overhauled in 1998 to establish the modern regulatory architecture. Three principal enforcement arms operate under FEFTA: (i) security export controls administered by METI via the Export Trade Control Order and the Foreign Exchange Order (covering the Wassenaar Arrangement, Australia Group, MTCR, NSG, and CWC controlled-items lists plus Japan-specific catch-all controls); (ii) inward FDI screening administered jointly by the Ministry of Finance and sector ministries (prior notification and pre-notification regime, substantially expanded 2019–2020 with Core Business Sectors covering semiconductors, critical minerals, advanced materials, cloud computing, and aerospace added 2021); and (iii) autonomous economic sanctions (asset- freeze and payment-restriction designations against Russia, Iran, DPRK, Myanmar, Belarus, and others via Cabinet Orders made under FEFTA authority). Structurally peer-foundational to the US Trade Expansion Act 1962, US Trade Act 1974, UK SAMLA 2018, CN Export Control Law 2020, and CN Anti-Foreign Sanctions Law 2021 as the G7+CN foundational economic- statecraft statute cluster.
