is a Japanese politician and current governor of Shimane Prefecture.
He ran for office as an independent during the Shimane gubernatorial election in 2019, winning 43.58% of the vote.[1]
In February 2020, he criticized South Korea over territorial disputes in the Liancourt Rocks, which Japan claims is as a part of Shimane Prefecture.
