In 2010, Ishikawa was embroiled in a political funding scandal involving Ichirō Ozawa. He allegedly failed to record 400 million yen he and other secretaries borrowed from Ozawa to buy land in Tokyo.[3] After he was indicted in February 2010, he resigned from the DPJ and sat in the House as an independent. Ishikawa retained his seat during the appeal process. He joined New Party Daichi in 2011 and contested the 2012 election under their banner. He was defeated in his seat by Shōichi Nakagawa's wife Yūko, but was returned to the House though the NPD's PR list. His legal issues led him to resign from his seat in May 2013, when he decided to fully focus on his appeal to the Supreme Court. He was replaced by NPD leader Muneo Suzuki's daughter Takako, who was next in line in the PR list.[4] His appeal was rejected by the Supreme Court in September 2014 and he was sentenced to 2 years in prison, suspended for 3 years.[5]

Ishikawa has limited involvement in politics since then. He returned to the DPJ in 2015. He also completed a master's course in Hosei University in 2016, majoring in political science. As part of the degree, he conducted a comparative study between the New Labour reforms of British Prime Minister Tony Blair and the DPJ.

In the 2017 election, Ishikawa's wife Kaori was elected to his former 11th district seat, defeating Yūko Nakagawa.
