The Kaew duology

In preparation for the title fight, Anpo added former boxing world titlists Hozumi Hasegawa and Tomoki Kameda to his fight camp, as well as conditioning coach Masayoshi Hideshima.^[23] Anpo had trouble making weight for the bout, missing by 150 g on his first weigh-in, but making weight after removing his shorts.^[24]

The fight was ruled a majority draw after the first three rounds were fought, with one judge scoring the bout 30-29 for Kaew, while the remaining two judges scored the fight as a draw. Accordingly, an extra round was fought, during which Kaew was deducted a point for pulling down Anpo's head. Anpo won the fight by unanimous decision, with all three judges scoring the last round 10-8 in his favor.^[2] The decision to deduct a point was seen as controversial, with Combat Press awarding this bout their "Robbery of the Year" award, and declaring that "the referee blatantly robbed him of a victory when he handed [Kaew] a yellow card".^[25] During the post-fight interview, Anpo stated his dissatisfaction with how the fight ended and called for a rematch with Kaew.^[26]
