Ayaka Miura vs. Chihiro Sawada and more added to ONE Samurai 1 on April 29 in Tokyo

ONE Championship has added three MMA bouts to ONE Samurai 1, going down live on Wednesday, April 29, at Ariake Arena in Tokyo, Japan. The event now pits two of Japan’s most dangerous grapplers against each other.

Ayaka “Zombie” Miura faces Chihiro Sawada in an all-Japan atomweight MMA clash. Miura, a third-degree judo black belt and former osteopathic clinical educator, enters at 16-5 and riding a five-fight winning streak built almost entirely on submissions.

Eight of her nine wins inside ONE have come by finish. Her title shot against Denice Zamboanga at ONE 173 last November was scrapped when the champion withdrew due to illness. Now, she faces a legitimate threat to her championship ambitions in Sawada, who brings an 11-1 career record, a strong wrestling base, and three straight wins of her own into the all-Japan collision.

Also added is a strawweight MMA matchup between Keito “Pocket Monk” Yamakita and Ryohei Kurosawa. The 29-year-old Yamakita enters at 11-1 and has strung together three consecutive victories, with wins over former ONE World Champions Alex Silva and Yosuke Saruta underlining his credentials.

Kurosawa, a 32-year-old veteran from The Blackbelt Japan, brings a 20-5 record and 11 finishes into the contest. He won his promotional debut convincingly in 2025 before dropping a decision to Bokang Masunyane.

Hirata and Phogat finally get their rescheduled clash at ONE Samurai 1

The third addition completes unfinished business. Itsuki “Android 18” Hirata and Ritu “The Indian Tigress” Phogat were originally scheduled to meet at ONE 173 last November before the bout fell apart. The matchup is now officially rebooked for Tokyo.

Hirata enters needing a bounce-back performance after Sawada handed her a unanimous decision loss at ONE 173. The 26-year-old judoka carries six ONE wins and dangerous submission and ground-and-pound skills. But she has managed just two victories in her last seven appearances.

Phogat, a 31-year-old decorated wrestler turned MMA fighter, brings a 7-4 record into the contest. She won seven of her first eight professional bouts, reached the ONE Women’s Atomweight MMA World Grand Prix final, and returned from a hiatus to have a child in 2022 before suffering a first-round submission loss to Miura last year.
