Misaki Matsutomo and Ayaka Takahashi reached the women's badminton doubles final at the Rio Olympics on Tuesday, assuring Japan of at least a silver medal.

Later at the Riocentro Pavilion, an all-Japan women's singles quarterfinal saw Nozomi Okuhara, ranked sixth in the world, maintain her unbeaten record over Akane Yamaguchi. It wasn't easy, as Okuhara had to fight back from a game down to win it 11-21 21-17 21-10.

With both sides attacking at every opportunity, the top-ranked doubles combination of Matsutomo and Takahashi defeated fifth-seeded South Koreans Jung Kyung-eun and Shin Seung-chan, 21-16, 21-15.
