The Japan High School Baseball Federation decided Wednesday to cancel this summer's edition of Japan's famed summer high school baseball tournament due to the coronavirus pandemic, meaning the nation's largest amateur sporting event will not be held for the first time since World War II.

The National High School Baseball Championship, a two-week tournament broadcast nationwide, was scheduled to open on Aug. 10 at Koshien Stadium in Nishinomiya, Hyogo Prefecture.

Organizers decided to cancel the tournament during an online steering committee meeting. The decision was made official at a board meeting later Wednesday, a source close to the matter said.
