- Genta Koja, backed by PM Sanae Takaichi, won Okinawa's gubernatorial election, ending 12 years of opposition to the US military presence and likely easing Tokyo's military plans.
- Koja's win may allow the relocation of US Marines and expanded military use of civilian facilities, supporting Japan's planned defence build-up amid rising China tensions.
- Takaichi's administration aims to boost defence spending in response to China's actions near Taiwan and Okinawa, with new security strategies set for 2026 implementation.

TOKYO – A candidate backed by Japanese Prime Minister Sanae Takaichi’s government won Okinawa’s gubernatorial election on Sept 13, ousting an opponent of Tokyo’s military build-up across the strategically important island chain near Taiwan and China.
Genta Koja, 42, defeated two-term incumbent Denny Tamaki, 66, with 59 per cent of the vote in a result announced early on Sept 14.
His victory, after a campaign dominated by concerns over rising prices, ends 12 years of rule by governors frequently at odds with the central government.
Tamaki’s defeat could weaken local efforts to halt the relocation of some US Marines from the busy Futenma airbase to a more remote facility at Henoko on Okinawa’s main island.
Opponents want the troops moved out of the prefecture instead. Japan’s government said on Sept 14 it would press ahead with the relocation.
Koja’s victory may also make it easier to expand military access to airports and ports, according to Masaaki Gabe, a professor emeritus at the University of the Ryukyus.
“Koja could reasonably be expected to approve their designation, opening wholly civilian facilities to military use,” Gabe said.
The Okinawa election result comes as Takaichi prepares to unveil a new national security strategy in 2026, which is expected to accelerate Japan’s biggest military build-up since World War II.
Her administration says increased defence spending is necessary to deter China from using military force to advance its territorial ambitions in East Asia.
Okinawa forms part of what military planners call the first island chain, a string of territory stretching from Japan through the Philippines that constrains China’s access to the Western Pacific.
Okinawa’s Yonaguni island lies just 110km east of Taiwan. Beijing claims Taiwan as its own territory and has stepped up military activity around the democratically governed island.
Tensions between Tokyo and Beijing have risen since Takaichi said in 2025 that a Chinese attack on Taiwan that also threatened Japan could trigger a military response by Tokyo.
