Score = concentration + substitution + lead time + inelasticity, each 0–3, an analyst judgement dated 2026-09-15; open a score for its rationale and assessment. Makers are those the corpus records, not the whole market. No market-share figure is sourced, so none is shown.

05Ways to take part
Not investment advice. This says how the public can reach a company — a job, its shares, its products — not whether anyone should. It takes no account of anyone’s circumstances, and a company holding a chokepoint is not a reason to own it. What this is not
- Work there
- It publishes its roles on its own careers page.Official careers page ↗
- Own part of it
- No public listing was found for Tanaka Kikinzoku (checked 2026-09-24); there may be no way for the public to own its shares.
- Buy from it
- At this depth of the chain most sales are to other businesses, under contract. No page of its own is recorded here yet.
06Hiring

A loop is one design, build and measure turn. Severity is a dated judgement on a 0–12 scale, not a measurement, and the judgements are not added together — the figure shown is the worst single one.
