RIZIN New Year’s Eve 2025 Card: Full Fight List, Title Bouts, and Key Updates for Saitama Super Arena

RIZIN New Year’s Eve 2025 Card: Full Fight List, Title Bouts, and Key Updates for Saitama Super Arena

RIZIN’s New Year’s Eve tradition gets another stacked edition

Rizin FF has made December 31 feel like a holiday for fight fans, and RIZIN Shiwasu: no Cho Tsuwamono Matsuri looks built to keep that reputation intact. Saitama Super Arena is once again the stage, and the promotion is clearly leaning into the “end-of-year spectacle” vibe — big titles, big names, and a deep undercard that doesn’t look like filler.

Five titles, one night — and a major lightweight update

At the top of the card, the championship slate is loaded: Shaydullaev vs. Asakura brings star power and pressure, while Kubota vs. Izawa is a matchup that screams pace and urgency. There’s also the bantamweight title clash in Inoue vs. Sabatello, plus the flyweight title/GP final-style stakes of Motoya vs. Ougikubo.

The lightweight belt picture also shifts: champion Roberto de Souza now draws a new challenger in Ilkhom Nazimov. It’s the kind of late change that can turn a “safe” title defense into something unpredictable fast.

Undercard matchups that can steal the show

If you like the chaos tier of RIZIN cards, you’ll want to keep an eye on fights like Koike vs. Karamov and Shishimoto vs. Ashizawa. The mid-card is stacked too: Saito vs. Sugiyama, Ando vs. Fukuda, and Shinryu vs. Kondo all feel like “someone’s getting launched” energy. Add in Goto vs. Torres, Kubo vs. Dautbek, and Tomizawa vs. Shinotsuka, and you’ve got a lineup where the early fights matter.

One way or another, RIZIN Shiwasu: no Cho Tsuwamono Matsuri is shaping up like the kind of card where you can’t just tune in for the main event — because the weird, wild moment you’ll see clipped everywhere might happen two fights earlier.
