Early career

As an amateur Okubo amassed a record of 145 wins, 18 losses, 3 draws and captured over 40 titles. During 2021, his last year of competition before turning professional, Okubo won the two most prestigious titles of Japanese amateur kickboxing, the Japan Cup in March and the K-1 Koshien tournament in August.[2] He won four fights in one day during both tournaments. His Koshien success secured him a professional debut with the K-1 promotion.[3]

Okubo made his professional debut on February 27, 2022, at K-1 World GP 2022 Japan against Shohei Nishibayashi. He won the fight by unanimous decision.[4]

For his second professional fight, Okubo was invited on the exceptional card THE MATCH 2022 at the Tokyo Dome, on June 19, 2022, where he faced Ryujin Nasukawa, the younger brother of the card headlining star Tenshin Nasukawa. Okubo won the fight by unanimous decision.[5]

On September 24, 2022, Okubo took part in a 4-man tournament at Krush 141 with the inaugural Krush Flyweight (-51kg) title at stake. In the semifinals he rematched Shohei Nishibayashi and defeated him once again by unanimous decision.[6] Okubo advanced to the final where he faced Daina. The fight was declared a draw after 3 rounds and went to an extension round which Okubo won by split decision to capture the inaugural title.[7]

Okubo vacated his Krush flyweight title on April 14, 2023, in order to move up in weight.[8] Okubo made his debut at 53 kg on June 3, 2023, at K-1 World GP 2023 in Yokohama against Ryunosuke Saito. He lost the fight by extension round decision.[9]

On October 21, 2023, Okubo returned to krush to face Eito Kurokawa at Krush 154. He won the fight by unanimous decision.[10]
