Olympic gold medalist Satoshi Ishii officially signed with Sengoku today in front of approximately 3,000 fans during a public ceremony at Shinjuku Station Square. There was speculation that Ishii's first opponent would be announced as well - possibly fellow judoka Hidehiko Yoshida, who was in attendance - but nothing was mentioned. Ishii joked with reporters and said that his reason for choosing Sengoku over another MMA promotion was that he received a nice gift certificate from the president of discount retailer and main Sengoku sponsor Don Quijote. Ishii also confirmed that he will not wear a gi when he makes his MMA debut.

Speaking of gi's, Yoshida Dojo veteran Kazuhiro Nakamura was one of twenty or so fighters who showed up for the signing; however his Sengoku IX opponent, Kazuo Misaki, was not. Nakamura expressed his anger and said he will kill Misaki on August 2nd. Asked by a fan who he'd like to fight, Nakamura said he wants a rematch Wanderlei Silva, who once famously TKO'd Nakamura after the judoka removed his gi top mid-fight.

Daniel Herbertson has coverage of the signing over at Sherdog:

Keeping with the tradition of mixing MMA and comedy in Japan, Ishii attempted to live up to the humor of some of his peers on the Japanese scene. The 22-year-old strutted out to the stage wearing a sumo wig but quickly became embarrassed and tried to tear off the headgear when no one laughed. The laughter came soon after.

“I want to have exciting fights and become world heavyweight champion,” he said. “I’d like to fight at any time. If I can, I’ll come out Aug. 2 at [Sengoku ‘Ninth Battle’].”
