He has also competed in professional wrestling, working for the U-STYLE promotion led by his trainer Kiyoshi Tamura.

He spent his next years fighting in GCM and DEEP, where he challenged for the Welterweight Championship, losing an effortful match by TKO at the third round.

This was a notable matchup because both Tokoro and Nakamura both sported similar fighting styles, were trained by former RINGS wrestlers and were seen by Japanese pundits as the heirs of the shoot-style circuit.

Nakamura, however, capitalized to transition the move into an armbar, making Tokoro finally tap out.

Four years departed from his previous fight, Nakamura returned to face Tatsunao Nagakura at DEEP: 97 Impact.

[2] Nakamura then faced the reigning featherweight champion Juntaro Ushiku in a non-title bout at DEEP 100 on February 21, 2021.

[13] Nakamura faced Min Woo Kim at Black Combat 5: Song of the Sword on February 4, 2023.

[15] On July 14, 2024, he faced Rikuto "Dark" Shirakawa at DEEP 120 IMPACT, and although it was a close and heated battle, he lost by split decision.
