Yuta Kubo (Japanese: 久保優太, Kubo Yuta, born October 19, 1987) is a Japanese mixed martial artist and former kickboxer, currently competing in the featherweight division of Rizin Fighting Federation.

As a professional kickboxer, Kubo is the former Krush and K-1 welterweight (-67.5 kg) champion. Kubo was furthermore the 2011 K-1 World MAX Lightweight (-63 kg) Japan Tournament winner, 2013 Krush Welterweight (-67.5 kg) Grand Prix winner, 2013 Glory 65kg Slam Tournament Winner, and the 2017 K-1 World GP Welterweight (-67.5 kg) World Grand Prix Winner.

Combat Press ranked him as a top ten featherweight kickboxer in the world between September 2014 and July 2016,[2][3] as well as between April and July 2020.[4][5]

Controversy

In September 2016, Kubo was detained and arrested by the Tokyo Metropolitan Police Department on allegations of assault causing bodily harm raised by his then-wife. According to his ex-wife's testimony, she was verbally and physically assaulted by Kubo, who was upset over a failed stock investment. Kubo punched the woman several times in the head, causing eardrum rupture in both of her ears, which left long-term residual effects in one of the ears. After divorcing, the two reached an out-of-court settlement, which obliged Kubo to pay his wife an undisclosed amount in damages, but spared him from being prosecuted by the Public Prosecutors Office.[6]

On June 8, 2012, At Krush 18 in Tokyo, Japan, Yuta faced Abdellah Ezbiri.[60] Despite his aggressive style Ezbiri seemed gun shy in the 1st round giving it to his opponent. Yuta dropped Ezbiri twice in the second, the 1st time with a right hook, the second with a spinning back fist but got up both times showing extreme toughness and heart and stayed on his feet in the 3rd even though Kubo is known for finishing his opponents quickly when he smells blood. Yuta Kubo won the fight by unanimous decision.[61]

Kubo faced Yuya Yamato at Krush.22 on August 26, 2012.[62] He won the fight by a second-round knockout.[63]

Krush Welterweight Grand Prix

Kubo competed in the Krush Grand Prix 2013 ~67kg First Class Tournament~ on January 14, 2012 and was initially set to fight Houcine Bennoui in the quarter-finals.[66][67] However, Bennoui pulled out and was replaced by Roman Mailov.[68][69] Mailov then sustained an injury in training as well, though, and lowly-ranked TaCa was brought in as Kubo's third opponent.[70] He stopped TaCa with one of his signature body shots in round two. In the semis, Kubo dropped Shintaro Matsukura with a first round punch to the body and cruised to a unanimous decision but not without taking significant damage to his lead leg. A rematch with Abdellah Ezbiri then awaited him in the final. Kubo started the fight well but the tide started to turn in round two when Ezbiri began taking advantage of his injured leg to the point where he was having trouble standing. The bout was scored a unanimous draw after the regulation three rounds and so it went to a first extension round which was called a majority draw, much to the distaste of the crowd who booed the decision as they believed Ezbiri was dominant. Kubo rallied in the second extension round to take a unanimous decision, winning the tournament and the inaugural Krush 67 kg title.[71]
