Sources and licences
The data comes from public sources. We process it and keep a reference to where each record came from.
EDINET (Financial Services Agency of Japan)
Annual securities reports, half-year securities reports, large shareholding reports and filing metadata, fetched through the EDINET API. Used under the Public Data License 1.0 with this attribution: “Source: EDINET (Financial Services Agency of Japan); processed by JapanStake.” Documents are read through the API only, never by scraping the EDINET website, and requests are paced to keep the load light.
SEC Form N-PORT data sets
U.S. registered funds' holdings of Japanese stocks, from the quarterly data sets the U.S. Securities and Exchange Commission publishes. Only each fund's latest report in the quarter is used. Values are in U.S. dollars as filed.
OpenFIGI
Financial Instrument Global Identifiers for each ticker, and the ISIN-to-ticker mapping for fund holdings.
What we change
- Japanese labels become English field names. English company names come from the EDINET code list and each company's own filings.
- Ownership changes, threshold crossings and statements that a filer may make proposals are derived from the filings by rules.
- Cross-shareholdings are matched to tickers by company name; renamed or delisted companies may stay unmatched.
What we leave out
We do not collect birth dates, home addresses or phone numbers. Filers and holders in ownership data who are not recognisably organisations are shown as individual filer or individual holder; the source filing stays linked. Officers appear by title only, and meeting candidates are not named. Names of natural persons in filing text are replaced with [氏名省略] where we can recognise them.
