A rematch and a vacant belt headline the first announced bouts for HOOST CUP Kings Nagoya 20, and both title fights carry a story from the last year of the promotion.
Yuhi and Leon already know each other well. They fought for the then-vacant flyweight title in September 2025, and Yuhi took it by a 2-1 split decision, the narrowest kind of verdict. Leon now returns as the No. 3 flyweight in NKB's rankings and has had a reason to be confident: in June in Nagoya he beat a respected domestic lightweight-division contender.
Yuhi has not been idle as champion. In March in Kyoto he beat Shoot Boxing top contender Daiki Kobayashi, whom he had drawn with before, and scored a knockdown on the way. That win gives him momentum going into a fight where the margin last time was razor thin.
The lightweight title is open because former champion Takuki Naruo gave it up. Yasukawa, a former HEAT lightweight champion, put himself forward. He has been a HOOST CUP regular since July last year, when he beat Innovation top contender RISING Daiki. He then challenged Naruo in Osaka in September and lost. Since then he beat NJKF-ranked Taiji Sobue in December in Nagoya and knocked out Takuya Taira in March in Kyoto.
Sato is the former NJKF super featherweight champion and was picked because of an earlier HOOST CUP win over Henry Sehas, who had pushed Maki Pinsayam hard. He arrives on a three-fight losing streak, which makes this a chance to turn his run around and add a second belt.
The full card is still to be announced, with more bouts to follow ahead of Dec. 13 at Nagoya Kinjo Futo Arena in Aichi.
