Soru Hamaguchi headlines DEEP Fight Challenge 2026#03 on Friday, Oct. 30 at the Ebisu Garden Room in Meguro, Tokyo, against Onigiri-kun in a 58 kg contract bout over three five-minute rounds.

Hamaguchi told MMAPLANET he developed a retinal detachment about a week after the September DEEP Osaka fight with Ryosuke Honda was set, and had surgery right away. The promotion had announced only that he was out with a training injury. He said doctors cleared him after about a month and a half, and he accepted the October bout at short notice.

He stopped Yuma Matsui in March and Kato Sunada in May at RIZIN Kobe, and has since moved his base to Nagoya to train under Kanten Kasugai. He wants four fights this year and is looking at New Year's Eve. He said he won't trash talk: "I'm a fighter, so [I'll show it] in the fight" (translated).
