Okinawa’s gubernatorial election concluded on September 13, with independent newcomer Genta Kosa, jointly endorsed by six political parties including the Liberal Democratic Party (LDP) and Nippon Ishin no Kai (Japan Innovation Party), defeating incumbent Governor Denny Tamaki, who had sought a third term.Kosa, 42, won more than 420,000 votes, comfortably ahead of Tamaki’s roughly 270,000 votes. His victory marks a major setback for the “All Okinawa” reformist camp, which has opposed the relocation of U.S. military bases within Okinawa. It also brings a political change in Okinawa for the first time in 12 years, with the pro-central-government camp returning to power.

After his victory, Kosa said voters had chosen a path that would allow Okinawa to continue moving forward. He said his administration would prioritize issues affecting people’s daily lives, including rising prices, industrial development, childcare and support for vulnerable families. Kosa also expressed his respect for Tamaki, who had served as governor for eight years.Tamaki said he respected the election results and accepted the decision made by voters.Kosa’s victory also makes him the youngest governor in Okinawa’s history and the first governor born after Okinawa was returned to Japanese sovereignty in 1972.

Analysts say the focus of Okinawan elections has gradually shifted from the issue of U.S. military bases toward economic and livelihood concerns. Against the backdrop of inflationary pressures and growing regional security tensions, Kosa’s platform of economic revitalization and closer cooperation with the central government successfully attracted younger and moderate voters.Observers believe that with the LDP-backed camp regaining control of the prefectural government, relations between Okinawa and Japan’s central government are likely to improve. This could facilitate security policies such as defense infrastructure development across the southwestern island chain and the deployment of Japan’s Self-Defense Forces, potentially having significant implications for Japan’s regional security strategy and strategic cooperation around the Taiwan Strait.
