Cage Force 12 Results: Hironaka Clobbers Koyama for Vacant LW Strap

Former UFC welterweight Kuniyoshi Hironaka continued his successful shift to lightweight in Tokyo on Saturday, knocking out top prospect Yoshihiro Koyama to become Cage Force's third generation lightweight ace. (The belt was officially vacated by now-Sengoku champ Mizuto Hirota last week.) Hironaka notched his third straight stoppage win in the last four months, as he put  Koyama to sleep via left hook with under a minute left in the first frame.

In the night's sole women's match, Kyoko Takabayashi got back on track following her featherweight tournament loss to "V Hajime" Yamaguchi, TKO'ing the Wajyutsu Keisyukai-trained Akiko Naito in the first round. Meanwhile, former Outsider Masato Kobayashi improved to 4-0 with a unanimous decision over the more experienced Daisuke Sugishima.
