In a brief interview with Sponichi, Yusei Kikuchi's father offered up his thoughts:
"If he says he wants to go the US after he graduates from high school, I won't say no. I don't want him to live with any regrets and I want him to play where he wants to play."
According to some reports, Kikuchi's father was originally worried about his son and wanted him to start his pro career in Japan. But after seeing and hearing about how much his son wants to go the Majors, it appears he has changed his mind.
However, Yusei Kikuchi has yet to discuss the matter with his parents and things may change again at that point.
