Eleven players have appeared in three Olympics, the most by a Japanese player; one of them, Mamoru Takashima, played in 19 games, the most of any player.

One player, Shoichi Tomita, has been inducted into the International Ice Hockey Federation Hall of Fame, though as a builder and not for his playing career.
