On May 4th, RIZIN Otoko Matsuri storms back into the iconic Tokyo Dome, delivering a night of high-stakes showdowns and unforgettable drama. Headlining the event, featherweight champion Kleber Koike puts his belt on the line against undefeated Kyrgyz sensation Razhabali Shaidulloev, a rising powerhouse with fight-ending power. The co-main event features the electrifying return of Mikuru Asakura, who steps into the ring against former champion Chihiro Suzuki in a battle between two of Japan’s biggest stars. Adding to the spectacle, RIZIN’s first Heavyweight Grand Prix in nearly a decade kicks off, promising chaos, knockouts, and the birth of a new heavyweight king.

RIZIN 27 live from the Nippon Haishi Hall in Nagoya, Japan. The spotlight shines on Rizin women’s atomweight champion Ayaka Hamasaki. The 38-year-old Invicta and Deep Jewels veteran is among the best 105-pound ladies to ever grace a ring or cage, and she has yet to slow down. Hamasaki is 21-3 in more than 11 years of action. Two of her losses came in strawweight affairs against Claudia Gadelha and Livinha Souza. Her third stumble came in a recent trilogy fight with perhaps the only woman that can be considered her equal, Seo Hee Ham. Now, Hamasaki puts her belt on the line in a rematch against Kanna Asakura.
