Kotetsu Boku has signed with Rizin. The 42 year old appears to have been released by ONE Championship after losing three in a row but didn’t have to wait long to find a new home.

Boku’s signing was unveiled at Rizin 21 last Saturday. The former ONE Championship lightweight champion looks set to face off against one of the promotion’s biggest stars.

A bout between Boku and Mikuru Asakura is penciled in for Rizin 22. The event is set for the Yokohama Arena on April 19th.

Boku (26-14-2) signed for ONE Championship in 2012 and was handed a title shot in his promotional debut. He became the first man to ever hold the promotion’s lightweight belt.

Asakura (12-1-0-1) is 16 years his junior and riding an eight fight winning streak. He has emerged as one of the biggest stars on the Rizin roster and has a big following on Youtube.

Also in the works for Rizin 22 is a bantamweight title bout. Manel Kape (15-4) looks set to defend his belt against Hiromasa Ogikubo (20-4-2) on April 19th.
