A former student activist and freelance writer, Hosaka has consistently championed progressive causes, including opposition to nuclear power, support for selective married-surname systems, and the implementation of the 'Setagaya Model' for COVID-19 testing. He is known for his independent political stance, having left the Social Democratic Party prior to his first mayoral election.
