Hawkish former Tokyo Gov. Shintaro Ishihara, the supreme adviser to Jisedai no To (Party for Future Generations), on Tuesday officially put an end to his nearly 50-year political career after losing his Diet seat in Sunday’s Lower House election.

“I have no regrets. I feel relieved,” Ishihara said during a news conference at the Japan National Press Club in Tokyo, adding that he hopes to now devote his time to supporting young contemporary artists.

Ishihara, 82, said before the snap election that his physical strength was deteriorating. But after pleas from fellow members of the extreme right-wing party, he decided to run to support them. Still, Ishihara appeared to have little appetite to continue in politics, putting his name at the bottom of the party’s proportional representation list for Tokyo.

“I believe I have fulfilled my duties to my fellow members,” he said.

Jisedai no To, which put priority on the creation of a new Constitution, won a mere two seats Sunday, down from 20 prior to the election.

“I believe the public has little interest in the Constitution,” Ishihara said. “Disappointingly, those who really feel the need to change the Constitution have become a rare breed.”

Regarding the icy diplomatic ties between Tokyo and Beijing, Ishihara accused China of stirring tensions over the Japanese-controlled Senkaku Islands, which are also claimed by China and Taiwan.

“I would chase away (the Chinese vessels if I were prime minister),” he said.

Asked about a recent interview with a weekly magazine, Ishihara had even more scathing words on Tuesday.

“They asked me what I wanted to do most, so I told them that it’s to fight a war with China and win. I said that as a Japanese citizen,” he said.

Asked whether he hates China, Ishihara said that he does, adding that he hates communist China.

The outspoken politician, infamous for racist gaffes, triggered the ongoing diplomatic row between Japan and China by announcing in April 2012 a plan by the Tokyo Metropolitan Government to purchase three of the five Senkaku islets.

He initiated a fundraising drive for purchasing the uninhabited islets and sent a group of experts there to conduct research necessary for the planned purchase.

These actions prompted the central government, then led by the Democratic Party of Japan, to intervene and buy the islands from their Saitama-based owner in September that year, further denting ties between Tokyo and Beijing.

Ishihara abruptly resigned as Tokyo governor in October 2012 to run for the Lower House in hopes of making his long-held hope of creating a new Constitution a reality.

Linking up with Osaka Mayor Toru Hashimoto, Ishihara co-headed Nippon Ishin no Kai (Japan Restoration Party) and won a seat in the 2012 general election. But the two went their separate ways earlier this year, splitting the party in two.

Ishihara launched Jisedai no To in August with right-wing lawmakers, including Takeo Hiranuma, the current head of the party.

Despite his split with Hashimoto, Ishihara said he and the Osaka mayor are still on good terms. He said that Hashimoto is an excellent speaker whose oratory skills “rank with Hitler in his youth,” adding that the leader of Nazi Germany, however, later made “stupid” mistakes.

Ishihara entered national politics in 1968 at age 35, winning a seat in the Upper House with an unprecedented 3 million votes. He switched to the Lower House in 1972 and later served as Environment Agency chief and transport minister under the Liberal Democratic Party administrations.

Ishihara, whose late younger brother, Yujiro, was a famous actor, resigned from the Diet in April 1995, and later, in 1999, won the Tokyo gubernatorial race. Hugely popular with conservative voters, he was re-elected three times.

During his years as governor, Ishihara pushed through initiatives such as a new tax system for big banks and strict diesel vehicle exhaust regulations.
