Daiki Hashimoto came from behind to win his maiden Japan national gymnastics championship on Sunday and take the lead in the qualification race for this summer's Tokyo Olympics.

Hashimoto, who started the day in seventh place from Friday's preliminary round, claimed a dramatic victory after earning 88.532 points in the men's final at Takasaki Arena for a two-day total of 173.365.

Wataru Tanigawa finished 0.637 behind the 19-year-old in the all-around competition over six apparatuses, which doubles as one of the qualifiers for the men's Olympic team event. Defending champion Kazuma Kaya was third.
