Kohei Uchimura failed to win his 11th straight national championship on Sunday, finishing third behind teenager Kakeru Tanigawa.
Uchimura, the two-time Olympic individual all-around gold medalist, scored 171.664 at Tokyo Metropolitan Gymnasium, while Tanigawa scored 172.496 to win his maiden title. Kenzo Shirai, the world champion in the floor and vault, was runner-up at 172.164.
At 19 years and two months, Tanigawa became Japan's youngest national champion. Naoya Tsukahara, a member of Japan's gold-winning team at the 2004 Athens Olympics, was previously the youngest, claiming the crown in 1996 when he was 19 years and four months.
