## Early life

Senga was born in Gamagori, Aichi Prefecture, where he started playing rubber-ball baseball as a third baseman until he graduated from middle school, then switched from third baseman to pitcher due to the manager of Gamagori High School baseball club, who saw the quality of Senga's throwing fitting more as a pitcher. Although Senga and his team never made it to either Japanese High School Baseball Championship or Japanese High School Baseball Invitational Tournament in Koshien Stadium, the owner of a sporting goods store in Nagoya recommended Senga to Kazuo Ogawa, then-the scout manager of Fukuoka Softbank Hawks, as a potential player to be drafted.
