A four-time national champion at the Japan Championships in Athletics, his personal best for 110 m hurdles was 14.06 seconds (a former Asian record).

[5] This gained him his first selection to represent Asia at the 1979 IAAF World Cup, but at that competition in Montreal he failed to finish the race.

[6] The second national title of his career came in 1980, but again he failed to defend it the year after, with Noriyuki Takahashi taking the honours in 1981.

[5] He returned as Asia's hurdler at the 1981 IAAF World Cup: his standard was somewhat below the global one and, although he not far off his season's best in eighth place, he was almost a second slower than the winner, Greg Foster of the United States.

[2] As of 2015, he remains one of only two Japanese men to win the sprint hurdles at the Asian Games, alongside 1970's winner Chikashi Watanabe.
