How we rank
- What counts. Private (unlisted) startups founded in Japan or operating mainly in Japan, including those with a US (e.g. Delaware) parent company. We exclude listed companies, companies majority-owned by or consolidated into a large corporate group, and companies that operate mainly outside Japan.
- The number. Total funding raised to date as published. We prefer the company's own cumulative figure (Company-stated). Where there is none, we add up the company's disclosed rounds (Summed by us). Failing that, we use a figure from a third-party database or media report (Third-party). The original Japanese wording, source and date are shown for every company.
- Equity vs debt. We rank on equity. Where a company gives the equity/debt split, we use only the equity part. Many Japanese releases quote a single total that includes bank loans, venture debt or grants. Those totals are marked incl. debt/grants, so the equity-only amount is lower.
- Lower bounds. A ≥ means the true total is at least that amount: some rounds were undisclosed, or our figure only covers rounds we could verify.
- Ties share a rank, marked with “=”.
- Valuations appear only where a company disclosed one or a named outlet reported it. We never estimate a valuation.
- Dates and currency. Figures are as of the date shown and may be out of date. US dollar totals are converted at the rate the company used, or else at the rate on the announcement date.
- Next step. We plan to check these figures against commercial registry filings (登記), which record each capital increase. Corrections are welcome. Please send a link to the original release.
