Shooto is pulling out all stops as part of its 30th anniversary year.
The promotion has announced it will put its flyweight and lightweight titles on the line on 6 May in Tokyo as part of the second round of its 30th Anniversary Tour.
Reigning flyweight champion Hiromasa Ogikubo will face Kiyotaka Shimizu, while Koshi Matsumoto will meet Naoyuki Kotani for the Shooto lightweight title.
A veteran of Shooto, Ogikubo (17-4) was last seen in action at RIZIN 11 where he faced Kyoji Horiguchi, but lost via a unanimous decision.
Ogikubo made his professional MMA debut in October 2006 where he defeated Nobuhiro Hayakawa via unanimous decision.
His opponent Shimizu (22-14-3) comes riding a three-fight win streak, having defeated Yoshiro Maeda at Shooto in January this year with a first round TKO.
Koshi Matsumoto (19-8-2) returns after more than a year to defend his belt against former UFC fighter Naoyuki Kotani.
Kotani (36-16-7) has had a mixed run in MMA, losing all three of his UFC bouts before returning to Shooto with a win in 2017.
Both Matsumoto and Ogikubo have been competing in RIZIN, but with ONE Championship now in the picture, events with RIZIN seem unlikely.
The second round of Shooto’s 30th Anniversary takes place at the Korakuen Hall on 6 May. More details to follow.
