RIZIN Fighting Federation’s annual New Year’s Eve show, RIZIN 45, has had multiple fights announced, including the retirement bout for Miyuu Yamamoto.

Yamamoto, 49, previously fought for the promotion’s super atomweight title, coming up short against Ayaka Hamasaki in 2020. For her final fight, she’ll take on Seika Izawa.

Izawa is the current RIZIN FF super atomweight champ, though the fight will be a three-round, non-title affair.

Promotion officials announced the news in a press release distributed Friday. Yamamoto (6-7), who got a late start in MMA, is a former multi-time amateur wrestling champion. She’s the sister of late K-1 and UFC star Norifumi “Kid” Yamamoto.

Seika Izawa (11-0) won the promotion’s super atomweight grand prix in 2022, capturing the title in the process and has defended it once since, while also winning a non-title fight under the DEEP Jewels banner earlier this year.

Also announced for RIZIN 45 on Friday, Kota Miura faces kickboxing KOUZI in an MMA bout, while Satoshi “Dominator” Yamasu faces Suguru Nii. UFC and Bellator MMA vet Shinsho Anzai will also be in action, taking on Igor Tanabe.

RIZIN 45 takes place January 31, 2023 at the Saitama Super Arena in Saitama, Japan. The following match-ups have been announced for the event:

  • Kyoji Horiguchi vs. Makoto Shinryu — flyweight title fight
  • Juan Archuleta (c) vs. Kai Asakura — bantamweight title fight
