Concentration Ten largest, combined Largest holder

How much of the company the ten largest shareholders hold between them (%). Japanese filings list trust banks and custodians under their own names, so a single line here often stands for many underlying investors.

Combined stake of the ten largest shareholders, and of the single largest, by fiscal year (%).

Holders and shares by class

The counts behind the percentages: how many shareholders sit in each class, and how much stock they hold. Shares are in trading units (tan'i) as filed — one unit is usually 100 shares.

Shareholder counts and holdings by class, every year on record. Treasury stock and odd-lot holdings are excluded, so the classes may not sum exactly to the issued total.

日本語版 — the named list of major shareholders → The ten largest holders are filed under their registered Japanese names — trust-bank omnibus accounts and transliterated custodian names that have no English equivalent — so they are not reproduced here. The Japanese edition carries the full name-by-name table, year by year.

Figures are the ownership breakdown as filed in each year's securities report, at that fiscal year's record date. Treasury stock and odd-lot holdings are excluded from the class percentages, so a company that holds much of its own stock will show classes summing to slightly under the whole.
