NAHA, Okinawa — A growing sense of insecurity over China is reshaping one of Japan’s most closely watched regional elections, as Okinawan voters head to the polls with questions about national defense, U.S. military bases and the island’s economic future increasingly intertwined.
The Okinawa gubernatorial election is scheduled for Sunday, September 13, with incumbent Gov. Denny Tamaki seeking a third term against former Naha Deputy Mayor Genta Koja, who is backed by Japan’s ruling Liberal Democratic Party. Official Okinawa government election records confirm the Sept. 13 voting date.
For decades, opposition to the heavy concentration of U.S. military facilities dominated Okinawan politics. But that political landscape is shifting as security concerns surrounding China, Taiwan and Japan’s southwestern islands become harder for voters to ignore.
The Japan Times reports that a stronger Japanese defense posture is gaining greater acceptance among parts of the Okinawan electorate, even as the long-running dispute over U.S. bases remains unresolved.
China factor enters an old political battle
Okinawa has historically carried a disproportionate share of Japan’s U.S. military presence, making the issue of American bases one of the most politically sensitive subjects in the prefecture.
But the security environment surrounding the islands has changed significantly.
Chinese military activity around the region, tensions surrounding Taiwan and the presence of Chinese government vessels near Japanese-administered islands have intensified concerns about whether Okinawa could find itself closer to a potential regional conflict.
A separate report noted that Chinese Coast Guard vessels have been operating intermittently inside Japan’s exclusive economic zone south of Yonaguni Island, an Okinawan island located close to Taiwan. Tokyo has described Beijing’s actions as unacceptable.
The geographic reality is increasingly important: Okinawa sits along the southwestern edge of Japan’s island chain, close to Taiwan and areas where Chinese and Japanese security interests increasingly overlap.
Voters are not necessarily focused only on security
Despite the heightened security debate, the election is not simply a referendum on China or U.S. military bases.
Economic concerns remain extremely important.
A recent survey cited by Stars and Stripes found that nearly 47% of respondents identified the economy, employment and measures addressing rising prices as their most important election issues, compared with 16.6% who cited U.S. bases and security.
The same reporting described the race between Tamaki and Koja as extremely close, with a substantial share of voters still undecided at the time of the survey.
That makes the election more complicated than a simple pro-base versus anti-base contest.
A notable shift on military expansion
Another survey conducted by the Okinawa Times and Asahi Shimbun found 45% support for strengthening Japan’s defense presence in the Okinawa region, compared with 34% opposed, according to reporting summarized by Infobae.
That represents a significant political development in a prefecture where resistance to an expanded military footprint has historically been strong.
The change is particularly noticeable among younger voters, with security concerns increasingly competing with the traditional anti-base narrative.
Still, the numbers should not be interpreted as blanket support for U.S. military bases. Support for strengthening Japan’s own defense capabilities and opposition to the concentration of American bases are not mutually exclusive positions.
Tamaki vs. Koja: Two very different approaches
Tamaki, 66, has long opposed the relocation of the U.S. Marine Corps Air Station Futenma from the densely populated city of Ginowan to the Henoko area of Nago.
Koja, 42, takes a different position.
He supports the relocation plan, arguing that moving Futenma to Henoko is the fastest route toward closing the existing Futenma facility. At the same time, he has argued that other parts of Japan should take on a greater share of the burden of hosting U.S. military facilities.
The difference could have consequences beyond Okinawa.
The Japan Times reported that Koja’s potential victory could strengthen Prime Minister Sanae Takaichi’s political position and potentially influence the future of the Futenma relocation project and Japan-U.S. relations.
The base issue is losing some of its political dominance
The transformation of the election debate is perhaps most evident in how the candidates themselves are campaigning.
The Japan Times reported earlier this month that the Futenma relocation issue had faded somewhat into the background, while the relationship between Okinawa and the central government in Tokyo became a more prominent campaign issue.
Tamaki has emphasized his willingness to challenge Tokyo when he believes Okinawa’s interests are being ignored.
Koja, meanwhile, has promised a less confrontational relationship with the national government while emphasizing economic revitalization.
That approach appears to resonate with voters concerned about household finances and employment.
The United States remains central to Okinawa’s security dilemma
The changing debate does not mean Okinawans have forgotten the decades of controversy surrounding the U.S. military presence.
The Wall Street Journal reported that concerns about U.S. bases remain deeply rooted, particularly among older residents, but that some voters increasingly see the American military presence as an established reality while paying more attention to economic conditions and the changing security environment.
That generational shift could be crucial.
For younger Okinawans, the central question may increasingly be less about the historical argument over whether Okinawa should host U.S. forces and more about how Japan should respond to a rapidly changing security environment while improving the region’s economic prospects.
A vote with implications far beyond Okinawa
The stakes of Sunday’s election therefore extend well beyond the prefectural government.
A Koja victory would give the national ruling camp a potentially important political breakthrough in Okinawa and could make it easier for Tokyo to advance its preferred security and base policies.
A Tamaki victory, meanwhile, would demonstrate that opposition to the national government’s approach remains powerful despite the changing regional security environment.
The election comes at a particularly sensitive moment for Japan, as Tokyo strengthens its defense posture across the southwestern island chain and continues to monitor China’s military and maritime activities in the region.
Japan’s government has increasingly emphasized deterrence and defense capabilities along the islands stretching toward Taiwan, while the U.S.-Japan alliance has also been adapting its military posture.
The Japan Times has reported that U.S. and Japanese forces are moving toward a more distributed missile and air-defense network across the southwestern island chain as both countries seek to strengthen deterrence against China.
The bigger question facing Okinawa
Sunday’s vote may ultimately reveal whether Okinawa’s political priorities are undergoing a fundamental transformation.
The old debate—U.S. bases versus no U.S. bases—is increasingly being joined by a new set of questions:
How much defense does Okinawa need?
How much military burden should the prefecture carry?
How should Japan respond to China’s growing military presence?
And can Okinawa improve its economy while remaining at the center of Japan’s national security strategy?
With the race still described as close in recent media polling, the answer will come from Okinawan voters themselves.
And whatever the result, the election is likely to send a message not only to Tokyo and Washington—but also to Beijing.
Why this story matters
The key development is not that Okinawa has suddenly abandoned its opposition to U.S. bases. The more accurate story is that China’s growing military and maritime presence is changing the context in which Okinawans debate security.
At the same time, polling shows that economic issues remain a major priority, meaning the election cannot accurately be reduced to a China-versus-America security contest.
That distinction is important for accurate reporting.
