During his affiliation with AJPW, he also served as the chairman for the Pacific Wrestling Federation (PWF), which is the governing body for all championships in the promotion.
He then became a teacher of classic Japanese literature in a high school in Ishikawa Prefecture, before pursuing a professional wrestling career in 1985.
In June 1989, Hase and Takayuki Iizuka went to the Soviet Union to be trained in sambo, where he learned one of his signature moves, the uranage.
Hase and Muto won the Super Grade Tag League in November 1993, defeating The Jurassic Powers in the final.
In 2000, he founded the multi-promotional Bad Ass Translate Trading stable with Keiji Muto, Taiyō Kea and Jinsei Shinzaki; Hase and Muto reformed their team to battle Jun Akiyama and Yuji Nagata on October 8, the rising stars of their respective promotions (NOAH and NJPW), and were defeated in a ceremonial passing of the torch match that highlighted the advancement of professional wrestling in Japan.
He tagged with Katsuhiko Nakajima and Satoshi Kojima to face Taru, Suwama and "brother" Yasshi of the Voodoo Murderers.
The match was originally supposed to have Kensuke Sasaki in it to team with Hase and Kojima, but he was replaced with Nakajima following an eye injury.
Sasaki was still a presence in the match, working ringside to keep Voodoo Murders' heelish antics at bay and entering the ring at one point.

[12] In April 2020, Hase was accused of "patronizing, sexist behavior and harassment" at the Tsubomi Cafe in Shibuya, Tokyo.
In the report, it was outlined that, along with fellow constituents of the Liberal Democratic Party, Hase had been using aggressive behavior towards female staff members, many of which had been abused prior to employment with the cafe.
The association aligned with the cafe, Colabo, stated that Hase "touched [a woman's] waist with both his hands when she was working to set up a tent".
