How to read this: each slice is a group of investors. Foreign and financial institutions are professional money; individuals are retail shareholders; other corporations are usually business partners holding strategic stakes. A large institutional slice generally means heavier analyst coverage and more trading volume.

How to read this: each line shows how one investor group's share has moved over recent years. A rising foreign or institutional line can signal growing professional interest; a falling one the opposite. Japanese companies disclose ownership once a year, so these are annual points — read the direction over several years rather than a single step.

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.
