How to read this: the largest shareholder group is the controlling owner and related parties — a big slice means tight control. Minority shareholders are the many small holders. The remainder is mostly institutional and foreign money, which the regulator does not itemise separately.

Trust banks such as Master Trust and Custody Bank appear at the top of most Japanese registers: they hold shares on behalf of many underlying funds rather than owning them outright.
