Pro Judo — a new way to explore international judo

If you follow the IJF World Tour and wish you could dig into results, match history, and “who’s really in form” beyond the official points list, I built something for that: Pro Judo.

It’s a free stats site at projudo.xyz — not affiliated with the IJF, and not a replacement for the official world ranking. Think of it as a fan project that organises public IJF data so judo nerds (like me) can actually explore the sport.

What it is

Pro Judo pulls together IJF World Tour history: Grand Prix, Grand Slam, Worlds, and similar senior events. For each athlete you get:

Medals and major titles (Olympics, Worlds, Paris Grand Slam, and more — built from gold-medal history)

Every contest we have on record — wins, losses, opponents, rounds, tournaments

An ELO rating that updates fight by fight, not from placement points alone

Country pages — medals by year, strongest athletes, how nations compare

Upcoming entries on athlete profiles when they’re registered for Seniors calendar events

Coverage runs from 2009 through the present, with thousands of athletes, matches, and podium results in the database.

ELO — the bit that makes it different

Beside many names you’ll see a number that looks a bit like chess or esports: everyone starts at 1000, and each IJF contest nudges ratings up or down based on who you beat and who beat you.

Beat a favourite? Not much changes. Pull off an upset against a highly rated rival? Big swing.

That’s not the IJF world ranking. The federation ranks athletes mainly on tour points from placements. Pro Judo’s ELO is separate: it only cares about individual fights, processed in chronological order across a career. On a profile you can see the ELO chart — momentum before a big weekend is often clearer there than on a static results list.

The FAQ on the site explains the model in plain language if you want the full version.

What you can do there

Search any athlete by name, or type a country code (e.g. JPN, FRA) to jump to that nation’s page

Browse the leaderboard — filter by men/women, weight division, country, active vs all-time

Check Top 25 lists on the home page (by ELO and by country)

Spot active athletes with a small green dot (competed this year or last on the World Tour)

Sign in (magic link, no password) to claim your profile, follow athletes, and see upcoming tournaments for people you follow on your dashboard

The site is in English and French — switch language from the flag in the nav.

For athletes and coaches

If you compete on the World Tour, you can claim your profile after signing in so fans know it’s you. You don’t need an account just to browse — everything public is open without logging in.

Why I built it

Judo has incredible depth — same names across years, divisions, countries, upsets, rematches — but it’s scattered. I wanted one place to answer questions like: How strong is this athlete really? How did their rating move after Paris? Who’s entered for the next Grand Slam? How does my country stack up?

projudo.xyz is the answer I wished existed. It’s still evolving; if you spot gaps or have ideas, there’s a contact page once you’re signed in.

If you train, coach, referee, or just watch IJF streams on weekends — I hope it’s useful. Share it with anyone who argues about seedings at 11 p.m.

See you on the tatami.
