Pick a company to see where it actually produces — every country in its footprint, shaded by capacity share — overlaid with the countries whose register actions name it (severity ring + action count), plus violet arcs to the chokepoint countries its material inputs depend on. The map is a lens; the dossier and register are the source of record.
Tokyo Ohka Kogyo Co., Ltd. (TOK) produces across 5 countries — 55% of mapped capacity sits in 🇯🇵 Japan (HQ 🇯🇵 Japan).

No register action names Tokyo Ohka Kogyo Co., Ltd. (TOK) yet — footprint only.
Its 4 scored input materials trace to 1 supplier country — 1 refines >70% in a single country. Top input chokepoint: 🇨🇳 China (tungsten 90%, cobalt 78%, tin 55%, +1) — nearest ex-🇨🇳 tungsten producer: 🇦🇹 Austria ~4% — ~6-12mo to ramp (share-of-stage heuristic, not a sourced qualification time).Armed chokepoint: 🇨🇳 China has itself issued 8 register actions restricting the inputs it already dominates — cobalt (4), tungsten (4) — max severity 5/5. This share is a demonstrated lever, not just a concentration.Latest: China State Council Order No. 839 — Regulations for the Implementation of the Mineral Resources Law · 2026-05-20 · 141d ago

Reading the map: green shading = the company's production countries by capacity share, with dots at facility cities (dashed = approximate, country-level). Violet arcs = INPUT DEPENDENCIES — they run from the country that dominates world production/refining of a material the company consumes to the company's base; the % is that country's share of world supply at the named stage, NOT an import/export volume. Severity rings = countries whose register actions name the company.
