After training in the Último Dragón Gym, Senga made his pro wrestling debut in Toryumon Mexico on December 11, 2004, under his real name.

After some events, Senga changed his ring name to Banana Senga and became a member of the salsa-themed heel stable Los Salseros Japoneses (Takeshi Minamino, Pineapple Hanai and Mango Fukuda) along his classmate Passion Hasegawa.

After the fall of Los Salseros, Senga was defeated by Ken45º and forced into his stable Ken Gundan, but the stable dissolved shortly after and Senga turned face, keeping his salsa mannerisms for comedic effect.

Senga also played Shibaten, a kappa-based character, and had a feud with Rei.

The two proved to be a very successful duo, wrestling a high-speed style reminiscent of the Motor City Machine Guns or Paul London and Brian Kendrick.
