      • 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.

      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.
