Sixteen-year-old Miu Hirano became the youngest player to win the national table tennis championships in women's singles Sunday, while Jun Mizutani won a record ninth men's title.

Hirano, who became the first Japanese to win a World Cup tournament in October, defeated four-time champion Kasumi Ishikawa 11-6, 12-10, 8-11, 11-9, 9-11, 11-6 in the final at Tokyo Metropolitan Gymnasium.

Hirano, a backup member of the bronze medal-winning Japanese women's national team at the Rio Olympics last summer, overcame a regular in Brazil in 23-year-old Ishikawa, who had won the last three nationals.
