Summer Kōshien

The Hanshin Koshien stadium

The Summer Koshien (otherwise known as National High School Baseball Championship), is an annual baseball tournament held in the Hanshin Koshien Stadium, in which 49 schools from the 47 prefectures in Japan that won their nation-wide qualifiers will battle through single elimination rounds.

Every prefecture has one team qualify for Summer Koshien by winning their regional tournament, with two exceptions. Tokyo is divided into Western and Eastern regionals, and Hokkaido is divided into Northern and Southern regionals. Hence, both of these prefectures have two representatives every year.

The first round pairings and byes are decided by lottery. 34 teams meet in the first round, and 15 teams with byes join in the second round (32 teams play in the second round). Therefore it takes either five or six wins for a team to win the championship.
