Foreign ownership of every listed Japanese company, read from the shareholder-composition tables of 3,167 annual securities reports. The whole set, free, one file.
Download the CSV — 3,167 companies, 442 KB, UTF-8. One row per issuer.
For each company: securities code, EDINET code, the company name and listing market exactly as filed, the fiscal period end, the filing date, and the ownership arithmetic — total trading units, units held by foreign corporations and other non-individual foreign holders, units held by foreign individuals, and the resulting percentage. The basis is trading units (単元), which is the basis the statutory table itself uses.
We enumerated every annual securities report (docTypeCode 120) filed to EDINET in the 400 days to 29 July 2026 by an issuer carrying a securities code, took the latest filing per company, and read the 所有者別状況 table from each filing’s XBRL rather than its PDF. Where a company filed for more than one period, the later submission wins.
Every row passed one arithmetic check before it was allowed in: the seven ownership categories of the statutory table must sum to the table’s own printed total. 3,167 of 3,167 rows pass. Rows that failed the check are not in the file — there were none in this vintage, which is a property of XBRL tagging rather than a compliment to anyone.
The fragments are what happens when you read the ends of that distribution one filing at a time. All 83 listed banks came from this file; so did Kioxia at 68.48%.
No prices, no market capitalisations, no valuations, no ratings — the file contains ownership arithmetic from statutory filings and nothing else. Company names appear as filed, in Japanese. A high or low number in this file is a fact about who is on a register on one date, not a view about any security, and the file contains no recommendation of any kind.
