Outspoken nationalist Shintaro Ishihara, supreme adviser to Jisedai no To (Party for Future Generations) and a former longtime governor of Tokyo, lost his Lower House seat in Sunday's snap election..

The 82-year-old veteran lawmaker had said he would retire from politics if he was unsuccessful this time around.

After stepping down as Tokyo governor in October 2012, Ishihara was elected to the Lower House that December, returning to the Diet for the first time in 17 years.
