Personally, I’m not a boxing fan but this bout relates to Kumamoto in a couple of ways.
In another article, Fukuhara said that he wanted to win the fight for Kumamoto:
「“I want to win and I want to deliver good news for Kumamoto,” Fukuhara said. “I want to thank the many people who made his title fight happen.”」
