The RIZIN API: Japanese MMA events, results & stats
RIZIN Fighting Federation as clean JSON · every card since the 2015 debut, full cards with MMA and kickboxing bouts, results within minutes of the verdict, per-fight and per-round stats from 2023, fighter records and per-country broadcast rights. Same schema and key as our UFC coverage.
Free 1-day trial · 100 requests · no credit card. Paid plans from $19/mo, cancel anytime.
What's inside
3 upcoming events already on the schedule · cards, venues and broadcasts included.
The only RIZIN data API
No Western sports-data API covers RIZIN. UFCalendar tracks it natively: full cards from the Saitama Super Arena numbered shows to the LANDMARK series and the New Year's Eve card, live results on a 5-minute cycle, and every bout tagged mma or kickboxing so mixed cards stay clean.
Round-by-round stats for Japan's biggest cards
From 2023 on, every RIZIN bout carries strikes landed, takedowns, knockdowns and time in position per corner, per round, with bout totals · plus the records of the crossover names who fought in both RIZIN and the UFC, stitched into one career timeline.

Questions
- What RIZIN data does the API include?
- Every RIZIN event back to the 2015 debut with full cards and results, per-fight and per-round statistics from 2023 on, fighter records and bios, and per-country broadcast rights. RIZIN publishes no official rankings, so the org's rankings flag is false.
- Is there any other RIZIN API?
- No mainstream sports-data API covers RIZIN. UFCalendar tracks it natively · the same live-results pipeline that covers UFC runs on every RIZIN card, including the kickboxing bouts.
- Does one key cover RIZIN, UFC, PFL, OKTAGON and BKFC?
- Yes · every plan includes all five launch organizations under one key and one schema; kickboxing bouts are distinguished by the sport field.
- Is this affiliated with RIZIN?
- No. UFCalendar is an independent publication; RIZIN data is reconciled from public sources and normalized into our schema.
