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.

How to read this: a high foreign or institutional share often means the stock is widely researched and more liquid; a high individual share means retail investors hold most of the company. Percentages are of voting units.

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.
