He graduated from the Department of Political Science at
Takushoku University in 1970, and before he graduated he began working for
Ichirō Nakagawa, a Japanese member of the House of Representatives. Nakagawa committed suicide in a hotel in January 1983 for unknown reasons. Suzuki hoped to run for his seat, but Ichirō's son
Shōichi Nakagawa, a Tokyo native, moved to Hokkaido to run for his father's seat, and Suzuki successfully ran for a seat in a neighboring district. He was elected in December 1983 as a member of the
Liberal Democratic Party (LDP). He left the LDP in 2002 and was arrested later that year for suspicion of accepting bribes from two Hokkaido companies. He did not run for reelection in the 2003 elections on the stated grounds that he was undergoing surgery to treat stomach cancer. His secretary
Akira Miyano was convicted of bribery in 2003, and Muneo was convicted of taking the bribes, failure to declare political donations, and perjury and sentenced to two years in prison and fined ¥11 million in November 2004. He remained free and in office as he appealed the conviction. Muneo ran for the
House of Councillors in 2004. He was defeated, but ran successfully for the
House of Representatives of Japan in the 11 September 2005 elections after forming the
New Party Daichi. He is the only elected member of the party. On 7 September 2010, the
Supreme Court of Japan unanimously upheld Suzuki's conviction and sentence. In response, Suzuki stated that he would file a complaint against the ruling. As the complaint was rejected, Suzuki was removed from office and the fine and prison sentence took effect. He was also banned from running for public office for five years after completion of the prison sentence. Suzuki was paroled on 6 December 2011 after serving one year in prison in
Tochigi Prefecture. == Later career ==
