It has to be tough to be a Japanese heavyweight kickboxer and not have the ability to fight for the hometown K-1. For the smaller fighters, KRUSH, RISE and a few other promotions run big tournaments that keep them busy year round, but for poor Kyotaro, his options seemed to be limited. So limited, in fact, that he decided to try his hand at professional boxing, where he would have more opportunity than on the non-existant K-1 circuit. After making his debut in December, it appears that Kyotaro will once again step into the boxing ring.
According to Nightmare of Battle, Kyotaro is set to do battle with Jae-Chain Kim, a Korean Heavyweight who is currently ranked ninth by the OPBF. The two will meet on March 6th at the legendary Korakuen Hall. [source]
