Japan's Naoya Inoue, the IBF and WBA bantamweight world champion, will take on the IBF's sixth-ranked challenger, Aran Dipaen of Thailand, on Dec. 14 in Tokyo, Inoue's Ohashi Gym said Friday.

The bout at Ryogoku Kokugikan in Tokyo, part of a world title doubleheader, will be Inoue's first fight in Japan since November 2019 when the 28-year-old beat Nonito Donaire of the Philippines by unanimous decision in the final of the World Boxing Super Series.
