He served as the governor of Nagano Prefecture from 2000 to 2006, became president of New Party Nippon, and has been elected to Japan"s legislatures. He initially failed the university entrance exams in 1975 and spent the next year studying in Tokyo to retake them. In 1976 he entered the Faculty of Law at Hitotsubashi University.
Tanaka married after graduating from university but divorced 11 months later.
Soon after, Tanaka became a focus of public attention in Japan for policies that represented a radical departure from the priorities of the Japan"s bureaucratic establishment. These included his policy of halting dam building, campaigning for environmental issues and abolishing the Nagano Press Club.
These policies were designed to address ruinous public development projects that had left Nagano and many other prefectures burdened by debts. Japan is one of the most heavily dammed countries in the world with more than 3,000 dams and virtually no unobstructed rivers.
In 2002, conservative assemblymen who were upset by Tanaka"s challenge to decades of pork-barrel politics forced him from office by passing a vote of no-confidence.
But in the ensuing election, Tanaka made a successful comeback, thanks to overwhelming popular vote. In August 2009 he relinquished his seat in the House of Councillors in order to contest the Hyogo 8th district in the House of Representatives general election, in which he defeated Tetsuzo Fuyushiba, who had held the seat for 23 years. As president of New Party Nippon, he served in the House of Representatives of Japan in the Democratic Party and People"s New Party parliamentary groups before becoming an independent (in terms of parliamentary group) in 2012.
In the 2012 House of Representatives election, he lost his seat representing Hyōgo"s 8th district to Kōmeitō newcomer Hiromasa Nakano – before 2009, the seat had been held by Kōmeitō"s former secretary-general, Tetsuzō Fuyushiba.
In 2000, Tanaka was elected governor of Nagano Prefecture, a rural prefecture in Japan, standing as an independent without the support of any major Japanese political party. He regained political office in the July 2007 election for the House of Councillors of the national Diet, the only successful New Party Nippon candidate in the election. He was replaced in the House of Councillors by Makoto Hirayama, who had placed third on the party"s ballot in the 2007 election.
In August 2005, Tanaka formed the New Party Nippon with a handful of reform-minded members of the House of Representatives.
