Three MMA bouts round out the newly finalized card for ONE SAMURAI 2, and the numbers tell as much of the story as the matchups themselves.
Keito Yamakita brings a 5-1 promotional record and a four-fight winning streak into his strawweight meeting with newcomer Koyuru Tanoue on August 8. The Japanese grappler's resume includes victories over two former ONE Strawweight MMA World Champions, Alex Silva and Yosuke Saruta.
His most recent outing ended with a submission of countryman Ryohei Kurosawa at ONE SAMURAI 1. Another win of that caliber could put the 29-year-old directly in line for a shot at undisputed ONE Strawweight MMA World Champion Joshua Pacio.
Tanoue arrives with no ONE Championship record to speak of, making his promotional debut against one of the division's hottest names. The Osaka native will look to author his own record-building run starting inside Tokyo's Ebara Wave Arena Ota.
Elsewhere on the card, Ayumu Yamamoto and Ryo Hirayama meet in a bantamweight matchup carrying very different stakes. Both fighters dropped their ONE debuts, and both now search for the first win of their promotional ledgers.
A clean record remains within reach for Subaru Mori, who steps in for his own global debut against Yusuke Sato in a lightweight bout. Mori's first appearance adds another blank slate to a card built largely around emerging Japanese talent finding its footing in the world's largest martial arts organization.
Yamamoto and Hirayama both know the sting of a losing ONE debut, and their meeting gives one of them the chance to finally register a win under the promotion's banner. Given the stakes, neither man can afford another setback in the bantamweight division.
Mori's arrival adds a fourth new name to the promotion's featherweight and lightweight MMA pool this card cycle, joining a broader wave of Japanese prospects testing themselves on home soil. Sato, his opponent, represents the first roadblock in what Mori hopes becomes a lasting run.
Yamakita's four-fight streak stands out as the most significant number on the MMA slate. Building statement wins over two former World Champions before turning 30 has vaulted him into title conversations that most strawweights spend years chasing.
Should Tanoue pull off the debut upset, he would instantly become one of the division's most talked-about newcomers, a reversal that would derail Yamakita's climb toward a shot at Pacio. That contrast, an established contender defending his position against a hungry unknown, defines the strawweight main draw of this card.
