NEWSAR · AI

Genta Koja has won the Okinawa gubernatorial election, defeating incumbent Denny Tamaki. Koja, who was backed by Prime Minister Sanae Takaichi's Liberal Democratic Party, secured 59 percent of the vote. Tamaki, who advocated for the relocation of a major U.S. military base out of Okinawa, has been governor for two terms. Koja's victory may signal an end to Okinawa's opposition to the relocation of U.S. Marines from Futenma air base to Henoko and could facilitate increased military access to civilian facilities. This outcome aligns with the Japanese government's plan to accelerate military build-up amid concerns over China's territorial ambitions.

Genta Koja beat two-term incumbent Denny Tamaki, who wants a major US military base to be moved out of Okinawa.Genta Koja has defeated two-term incumbent Denny Tamaki in the race for governor of Japan’s southernmost prefecture, potentially ending more than a decade of opposition to a United States military build-up in the region.He won 59 percent of the vote in Sunday’s election, officials announced on Monday.Recommended Stories list of 3 itemslist 1 of 3Japan protests as Russia’s Putin visits disputed Kuril Islandslist 2 of 3Japan builds up its ‘southern shield’ as faith in US security cover falterslist 3 of 3What is Japan’s new intelligence agency, and why is Tokyo building it?end of listKoja, a former deputy mayor of Okinawa’s capital, Naha, was backed by Japanese Prime Minister Sanae Takaichi’s Liberal Democratic Party. He beat Tamaki, 66, who has long pushed for a major US military base to be moved out of Okinawa.The 42-year-old will become the youngest Okinawa governor since the prefecture was returned to Japan from US rule in 1972. He will also become its first governor born after the reversion.His election could end Okinawa’s legal efforts to block the relocation of US Marines from the Futenma air base to a new facility at Henoko on the prefecture’s main island, according to Masaaki Gabe, a professor emeritus at the University of the Ryukyus.Gabe also said it may make it easier to expand military access to airports and ports.“Koja could reasonably be expected to approve their designation, opening wholly civilian facilities to military use,” Gabe added.Koja’s victory comes as Takaichi prepares to unveil a new national security strategy this year that is expected to accelerate Japan’s biggest military build-up since World War II.Her administration said increased defence spending was necessary to deter China from using military force to advance its territorial ambitions in East Asia.
