The Spring Tournament (known as Tokyo Metropolitan Spring Baseball Tournament) is an annual baseball tournament that is considered the preliminary to the Summer Tournament. Like with the Fall Tournament there is no location based West-East Tokyo division. The top 16 schools or teams that reached the fourth round get to be seeded for the Summer Tournament both in West and East blocks.
Winners and runners-up of the tournament in the 7 prefectures of the Kanto Region as well as the third and fourth place finishers of the prefecture-host of the tournament, amounting to 16 schools in total, are then qualified to participate in the Kanto Tournament.
