DEEP featherweight champ Dokonjonosuke Mishima won in his non-title fight against Toshiaki Kitada at DEEP Protect on Monday at the Shinjuke Face in Japan.
Imanari, who defeated Masakazu Imanari via majority decision in May to win the belt, took Kitada's back and rained down strikes for the referee stoppage victory at 2:51 of the second round.
Mishima's fight was one of two non-title bouts on the card. Also in action was DEEP women's flyweight champ Miku Matsumoto, who despite a weight disadvantage, submitted Hikaru Shinohara with an armbar in one minute.
