Yoshiaki Fujiwara
Despite the build-up of several injuries, Hashimoto continued to wrestle on and off in Zero-One, including teaming with Yoshiaki Fujiwara to get the NWA Intercontinental Tag-Team Titles for a third time, defeating Takao Omori and Shiro Koshinaka in June 2004. The two remained the champions until before Omori found a new partner in Shinjiro Otani to win the championship in August 2004. Going into 2005, Hashimoto left Zero-One and placed Otani in charge, citing financial problems as the reason for his departure.
