Kirk here with high school baseball tournament information. Tokai University Kumamoto Seisho Senior High School will play Hamamatsu Kaiseikan in the first game of the day on Thursday. Here’s the Japanese information and my source:
8月10日(木) 7:00開門 第5日 8:00 第1試合(1回戦)東海大熊本星翔 (熊本) - 浜松開誠館 (静岡) https://www.hanshin.co.jp/koshien/highschool/summer2023/schedule.html
Assuming that Tokai wins this game, the schedule for their subsequent games will also be published on this page.
