Grigorian Flattened Kaito With a First-Round Knockout
Marat Grigorian knocked out Kaito Ono at 1:51 of round one during ONE SAMURAI 1 on April 29, 2026. The featherweight kickboxing bout ended with Grigorian’s left hand and added an emphatic finish to the Tokyo card.
The matchup
Grigorian entered as one of kickboxing’s established veterans, while Kaito represented Japan on a card centered on local stars and international champions. Their featherweight contest was scheduled outside the title bouts on the event program.
The opening exchanges did not last long. Grigorian pressed forward and found a clean punch that put Kaito down, leaving the referee to assess whether the Japanese fighter could continue.
ONE recorded the finish at 1:51 of the first round. The knockout therefore settled the contest before it could develop into a longer tactical exchange or reach the judges.
A fast finish on a title-heavy card
The result was one of several decisive performances on the inaugural ONE SAMURAI show. The main event and other championship bouts drew much of the attention, but Grigorian’s quick win underscored the depth of the card.
Kaito was the opponent who lost; the official result identifies him as Kaito, while other coverage uses his full name, Kaito Ono. The outcome should not be confused with Grigorian’s earlier unanimous-decision victory over Rukiya Anpo at ONE 173 in November 2025.
ONE’s official event record confirms the knockout, round and time. That source also identifies the fight as featherweight kickboxing, keeping the result separate from the promotion’s MMA and Muay Thai contests.
