Hashimoto led the former Takeshita faction until refusing to stand in the 2005 general election due to a fundraising scandal, and died shortly thereafter. The remnants of the faction, formally known by this time as Heisei Kenkyūkai (Heisei Research Council), remained active under the leadership of Yūji Tsushima, who resigned prior to the 2009 general election, passing control to Fukushiro Nukaga. The faction raised much less in donations during the 1990s and 2000s than it did under Tanaka and Takeshita in the 1980s, as electoral reforms enacted in 1994, coupled with new campaign finance regulations and the ongoing economic slump that followed the Japanese asset price bubble, weakened the power of factions in Japanese politics.
