日本陸上競技選手権大会
Fujimori emerged at national level in 1978 with a win at the Japan Championships in Athletics, taking the 110 m hurdles title in a time of 14.29 seconds (the fastest non-hand-timed mark at the championships at that point). He ran a lifetime best of 14.06 seconds in May that same year – this was an Asian record for the discipline. Later that year he was chosen as Japan's representative in the Asian Games in Bangkok. There he finished with a slightly slower time of 14.33 seconds, but this was enough for the silver medal behind Wang Xunhua of China.
