How to use this site
What is this site? This site contains a directory of all members of the Japan Sumo Association (Nihon Sumo Kyokai) from the yearbook specified below. The data is presented in a number of different views which you select via a list of options across the top of the page. Some of the views have subsidiary choices which are separately listed when that view is selected.

The default view is the heya view in which heya are selected from an alphabetical list. When you click on the heya name, the personnel in that heya are displayed.

There are two rikishi views, "Rikishi by division" shows rikishi listed alphabetically within each of the divisions and across all divisions. "Rikishi by shusshin" shows rikishi listed alphabetically according to their registered place of birth.

The other lists are oyakata, gyoji, yobidashi, tokoyama, "other staff" (wakaimonogashira and sewanin), kabu and special categories (expanded below).

Most of the entries have pictures - the exceptions are rikishi who joined during the previous year but retired before the new directory was produced.
Links to Sumo Reference database All rikishi (and staff members who used to be rikishi) have a direct link to the Sumo Reference database entry for the rikishi. You just click on the shikona at the top of the entry in the case of the rikishi, or in the case of an oyakata, wakaimonogashira or sewanin, click on the shikona where it says Former Yokozuna _Chiyonofuji_ for example.
Picture history If you click on the picture of a member who has been active since 2000, you can access a composite picture of that member from each year of his membership back to the later of his debut/the year 2000. This feature is currently unavailable from the view "Makuuchi rikishi of the modern era".
Printing Views within sub-frames are subdivided so as to make them paginate cleanly for printing. You need to print just the sub-frame. In Firefox this is done by right-clicking within the sub-frame, selecting "This Frame" and then selecting "Print Frame...". In Chrome, you will need to open the sub-frame in a window or tab of its own. e.g. to print the members of Dewanoumi Beya, right-click on the name Dewanoumi in the heya list and select "Open link in new window". The new window can then be printed in the normal way.

Summary The summary pages show brief statistics of the heya and major changes since 2000. The links to the pages are arranged in pairs, with the left-hand link showing the summary of personnel in each heya at the start of the year and the right hand link showing any changes (heya closures, opening of new heya, heya inheritance and takeover and transfer of personnel between heya) which happened during the year. As with the main heya section, all rikishi (and staff members who used to be rikishi) have a direct link to the Sumo Reference database entry for the rikishi.
