After over a year of training (including a dark match for Fighting Network RINGS in May 1991), he joined Wrestling International New Generations (W*ING) in August 1991.

In 1992, he left W*ING and joined the Takano Brothers' Pro Wrestling Crusaders, under the ring name Benkei.

As PWC did not run regular shows, he transferred to Frontier Martial-Arts Wrestling (FMW) a year later.

Hosaka made his debut for FMW in 1993, siding with his W*ING friends Mr. Pogo and Mitsuhiro Matsunaga.

In 2000, he won three WEW Hardcore Tag Team Championships with Mammoth Sasaki, before leaving FMW in 2001 in an exodus that also included Masato Tanaka, Jado, Gedo, and Kaori Nakayama.

After fully recovering from his knee injury, Hosaka returned to the ring as a freelancer in November 2006, which included stints in Wrestling Marvelous Future, Team Vader, and Ice Ribbon, before retiring from active competition in February 2008.
