About sumorikishi
sumorikishi profiles the 70 sekitori — the salaried top two divisions of professional sumo: makuuchi (42) and jūryō (28). Each rikishi gets a page combining structured tournament data with a short narrative explaining who they are and how they fight.
The site is the English mirror of the Japanese parent site, which covers all six divisions (~600 wrestlers).
How it's built
- Facts come from sumo-api.com and Japan Sumo Association sources, refreshed daily during a basho.
- Narratives are generated by Anthropic's Claude at build time, from the same structured facts. No editorial speculation; if it isn't in the data, it isn't in the profile.
- Photos come from Wikipedia Commons under Creative Commons licenses, with author attribution on every image.
What it doesn't do
- No predictions, fantasy sumo, or betting.
- No commentary on judging or association decisions.
- No user accounts or comments.
Kimarite fingerprint
Every rikishi profile shows a "kimarite fingerprint" — the 82 official winning techniques compressed into five families: push (oshi), force (yori), throw (nage), twist (hineri), and trip (ashi-waza). It's a compact way to see fighting style across a career without reading the box scores.
