Report
GLADIATOR KICK 001, the launch card for GLADIATOR's new kickboxing division, ran on 2026/7/20 at W OSAKA in Osaka, Japan.
In the Part 1 (day session) main event — an 83kg catchweight bout over 3x3 minutes plus an extension round — Yamaguchi Shota (GENESIS/TEAM3K) went the distance with Koyama Kanta (KYOTO SEIKENKAI) and took a clean unanimous decision, 30-28 across all three cards. In the Part 2 (evening session) main event, a 61kg contract-weight bout, Rantaro (TEAM OGRE) outpointed R¥UZO (13Club'u) by unanimous decision, 30-29 x3.
On the undercard, Arao Yuta won a 2-0 decision (30-29 / 30-29 / 30-30) over Chae Changhyeon in a middleweight Muay Thai bout under open-finger-glove rules — though it was a rough, clinch-heavy fight for Arao, and both he and his coach Yoshitaka were quoted afterward calling it, in tone, "a loss" despite the win on the cards. In the Part 2 semi-final, Hori Kentoku (fighting as "Kentoku") needed an extension round to get past 18-year-old Atsushi Takayama at super bantamweight after the regulation three rounds finished level (1-0), winning the extension 3-0.
