[2] Outside of pro wrestling, he is also a politician, as he's a member of the Tokyo Bunkyo Ward Assembly as a food education instructor.

Nishimura joined the New Japan Pro Wrestling dojo in April 1990, while a senior in high school.

In August 1993, he went overseas to Florida for a extensive training excursion under B. Brian Blair, Hiro Matsuda and Don Jardine.

On August 26, 1994, he went to the Global Wrestling Federation and defeated Alex Porteau to win the GWF Light Heavyweight Championship; he would be its final champion before the promotion folded a month later.

He would be brought back to NJPW for one match in October 1994, before Nishimura returned to the States to resume his excursion.

In March 1995, he had a couple shots at the NWA World Heavyweight Championship, now held by Dan Severn, but lost both times.

First, he went to Canada to train under Tokyo Joe Daigo for a month, before going to Europe for Catch Wrestling Association.

In February 2006, he and old MUGA comrade Katsushi Takemura took part in Chikara's 2006 Tag World Grand Prix, where they made it to the semi-finals, before being defeated by Milano Collection A. T. and Skayde.

He was immediately paired with Keiji Muto for the annual Super Grade Tag League; they tied for third with the team of Shiro Koshinaka and Tatsutoshi Goto.

Nishimura's star was bright enough to warrant an earnest push, and he won the IWGP tag team titles with Fujinami.

Nonetheless, the bi-promotional duo of Mutoh and All Japan Pro Wrestling's Taiyō Kea were on the rise, and the two teams clashed over both the IWGP title and AJPW's World Tag Team Championship, both of which ended up around the waists of Mutoh and Kea.

On October 20, 2007, Nishimura announced that he and trainee Manabu Soya have signed with All Japan Pro Wrestling (AJPW) as full-time wrestlers, citing unhappiness with the erratic MUGA World scheduling.

In January 2011, he announced his candidacy for the Tokyo Bunkyo Ward Assembly, representing the People's New Party.

His cancer scare inspired his political career as a food education instructor, as his top priority was how to make the world healthier and how to direct it to preventive medicine.

The cancer had already spread to the lymph nodes outside the esophageous and the entire upper left side of his body, except his head.
