Introduction of the tournament:
Koshien is the high school baseball national championships taking place at Hanshin Koshien Stadium. All the teams are school’s clubs. Representatives from forty seven prefectures compete in the two week tournament in August. There is only one team that represents each prefecture, except Tokyo and Hokkaido send two to the tournament. Your team has to win the single elimination preliminary in June and July. It is a long way to make it Koshien since there are more than one hundred teams participating in the preliminaries in some prefectures. There are 3,917 teams participating overall in the preliminaries. This year, Kanagawa prefecture, known as one of the hardest prefectures to get through the preliminaries, had 190 teams followed by Aichi with 189, and Osaka with 181. Hokkaido (293) and Tokyo (267), separating north and south or west and east, allow two teams to attend Koshien. The prefecture with the least teams is Tottori with 24.
The last year’s winner is Maebashi Ikuei of Gunma prefecture. Osaka leads the most champion flags with 11 followed by Aichi’s 8. Wakayama, Hiroshima, Tokyo, and Hyogo have won 7 times while Ehime and Kanagawa won 6 times. Those prefectures are known as baseball kingdoms.
