Kamo, 60, took over last June and kept the club in the first division. But this season they finished bottom of the 16-team table in the first stage, collecting only seven points from their 15 games, three adrift of 15th-placed Kawasaki Frontale. The second stage kicks off on June 24.

Kamo managed Japan's national team from 1994 to 1997 before being dismissed during the qualifying campaign for the 1998 World Cup.
