All Japan Championship (pool)

The All Japan Championship is an annual international pool tournament founded by Kazuo Fujima in 1967, with an all-around tournament with multiple disciplines, in the men's division up until 1990. In the Men's tournament the current discipline is ten-ball, however the Women's tournament is played in the discipline of nine-ball. The All Japan Championship is currently sanctioned by the JPBA. The first 20 years only held men's competitions. It was not until the 21st competition in 1988 that the women's event was established. Most of the competition period is after the middle of November each year. This is the most famous international large-scale pool event held in Japan, and the oldest tournament in pool that is still held.
