明治神宮野球場
The six teams play short, eight-weekend seasons in the spring and autumn of each year. Each team plays a short series against each of the five other teams in the league. The series format is similar to a three-game playoff, where the first to two wins is given a series victory. Home field is alternated, and all games are played at Meiji Jingu Stadium. Should a team sweep the first two games, the third game is not played.
