Nosawa spent most of his early career training and wrestling in Mexico, most notably with Consejo Mundial de Lucha Libre (CMLL).

Along with Mitsunobu Kikuzawa, Kazuhiko Masada, Minoru Fujita and Katsushi Takemura, Nosawa created the group "Tokyo Gurentai".

[5] On October 6, 2007, Corporal Robinson, Scott Hall, and Violent J formed the Juggalo World Order (JWO) at Evansville Invasion.

Nosawa would go on to make sporadic appearances on the early episodes of TNA Impact, usually teaming up with fellow Japanese rookie Kazushi Miyamoto.

The duo even challenged for the NWA World Tag Team Championship at TNA's second Anniversary show in June 2004, but ultimately came up short against America's Most Wanted.

The duo's last in-ring appearance for the company would be at Victory Road '04, where both Nosawa and Miyamoto competed in the X-Division Gauntlet match, which was won by Hector Garza.

Nosawa would originally find little success after arriving in All Japan Pro Wrestling (AJPW) in the mid-2000s, losing as many matches as he won.

Soon after that, he would reappear as a masked wrestler named Space Lone Wolf (Keiji Mutoh's old alter-ego), finding more success than his previous character.

[11] The following month, Dragon Gate wrestler Eita, who had previously worked in Mexican wrestling promotions and met Rongai in 2017, was revealed to be the newest member of the group.

[12] On June 27, at Muta The World, the stable's name was revealed to be dubbed Los Perros del Mal de Japón, as a tribute to the Mexican stable Los Perros del Mal after Eita, Rongai and Yo-Hey won against Stinger (Yoshinari Ogawa, Seiki Yoshioka and Yuya Susumu).

[15] At Grand Square 2021 In Osaka, Eita and Rongai defeated Atsushi Kotoge and Hajime Ohara to win the GHC Junior Heavyweight Tag Team Championship.

[16] At Noah The New Year 2023 on January 1, Rongai teamed up with Hiroshi Hase and Sugiura-gun members Kazuyuki Fujita and Kendo Kashin to defeat Kongo (Katsuhiko Nakajima, Masakatsu Funaki, Manabu Soya and Hajime Ohara).

[17] At The Great Muta Final "Bye-Bye" on January 22, Nosawa Rongai and Eita teamed up with Yoshinari Ogawa in a losing effort against Junta Miyawaki, Alejandro and Yasutaka Yano.

[18] On February 21, 2023, Rongai would have his retirement match where he teamed with Mazada in a losing effort against Bullet Club (Taiji Ishimori and Gedo).

[21][22] On July 9, Mexico-based Japanese wrestler Takuya Sugi held a press conference and confessed to planting the drugs on Shirai and Nosawa.
