Koshien 108th championship video review public viewing first‑time entrants

The 108th National High School Baseball Championship opened on August 5, 2026 at Hanshin Koshien Stadium in Nishinomiya, Hyōgo, and will run for 18 days until August 22, with three rest days. The opening ceremony began at 16:00 and featured a moment of silence and remarks from team captains. Video‑review technology is being used for umpire decisions for the first time.

Public‑viewing events were organized in Sano City Hall on August 6 for Sano Nittaidai High School’s first‑round game, and similar community screenings were held in other host cities. The tournament includes 49 schools from 47 prefectures, with some prefectures fielding two representatives. Notable first‑time participants are Kumamoto’s Ariake High School and Yokote High School, which returns after a 57‑year absence. Tickets for the opening match between Okinawa Shogaku and Yokohama sold out quickly, underscoring high public interest. The event also saw historic milestones, such as the first female bench‑staff member joining Sendai Ikuei’s team.
