Satoru Kitaoka submitted Cage Force lightweight champion Kuniyoshi Hironaka via second-round guillotine choke at Sunday's Pancrase Passion Tour show in Tokyo. After the win, the former Sengoku champ announced his retirement from Pancrase and defection from his longtime gym, PANCRASEism. Kitaoka also said that he hopes to fight on New Year's Eve, presumably at Dream parent company Fighting and Entertainment Group's annual Dynamite event. Elsewhere on the card, freestyle wrestling convert and Sengoku featherweight prospect Shigeki Osawa improved to 6-1 with a first-round TKO'ing of Masaomi Saito. Photo by GBRing.
