Kazunari Murakami

Big Mouth Loud (2005–2006) Having both left New Japan, Murakami and Katsuyori Shibata announced the formation of a new promotion, Big Mouth Loud in January 2005. Backed by Fumihiko Uwai, the promotion was set to focus largely on shoot-style, and would use talent from other promotions as well as their own contracted wrestlers. At Big Mouth Loud's first show in September 2005, Murakami defeated Shibata in the main event. Murakami reignited his feud with Enson Inoue at the next show in December 2005, defeating him in a singles match. Murakami continued to compete for BML until the promotion's closure in mid-2006.

Freelance (2006–2007)

After Big Mouth Loud folded, Murakami went freelance and began working for Pro Wrestling Zero1 in the summer of 2006. Murakami took part in ZERO1's 2006 Fire Festival tournament, making it to the semi-finals before losing to Shinjiro Otani. In the first match of the 2007 Fire Festival, Murakami suffered a severe brain injury against Shinjiro Otani, which forced him to leave professional wrestling effective immediately to undergo brain surgery.

Return (2010–2014) In February 2010 Murakami returned to pro wrestling, as Big Murakami, losing to Kensuke Sasaki in a match for Sasaki's Kensuke Office promotion. He also returned to Pro Wrestling Noah, and on March 26 teamed with Katsumi Usuda to challenge Takeshi Rikio and Muhammad Yone for the GHC Tag Team Titles but they came up short.
