Two-time spring champion Hotoku Gakuen High School, playing just a few kilometers from its school grounds in Nishinomiya, Hyogo Prefecture, took a 2-0 fourth-inning lead before surrendering seven runs in a six-hit fifth inning.

Yamanashi Gakuin was the first school from its prefecture to reach a Koshien final in either the spring invitational or the national championship.
