Okinawa votes on Futenma and a 12-year conservative return

Voting opened at 313 polling stations across Okinawa Prefecture on Sunday, 13 September. By 11:00 local time turnout stood at 8.14 percent, 0.95 points above the same hour in 2022. The prefectural election board listed 1,175,905 registered voters as of 3 September. Early voting through 11 September reached 273,584 ballots, or 23.26 percent of the roll, almost identical to the last race.

Six candidates filed. The contest is a two-person fight between Governor Denny Tamaki, 66, who wants a third term, and Genta Koja, 42, a former deputy mayor of Naha. The other four, all newcomers, are IT company president Shun Kaneshima, 48; medical corporation officer Masahiro Sueyoshi, 73; magnetic-survey company president Takashi Higa, 49; and Cho-suke Yara, 74, head of the Ryukyu Independence Party.

Henoko is the line that splits the two campaigns

Tamaki opposes the relocation of U.S. Marine Corps Air Station Futenma from Ginowan to the Henoko coast in Nago. The transfer rests on a 1996 Japan-United States agreement that was meant to reduce the risk the busy airfield poses to the city around it. Reclamation on the Henoko shore has already begun. Soft seabed under the fill has stretched the timetable and the cost. Tamaki is running without a party endorsement. He is backed by the All Okinawa grouping, which includes figures from the Constitutional Democratic Party, the Japanese Communist Party, the Social Democratic Party, the Okinawa Social Mass Party and Inochi no To, the former Reiwa Shinsengumi.

Koja accepts the Henoko plan. He is recommended by the Liberal Democratic Party, Nippon Ishin, the Democratic Party for the People, Sanseito and the Conservative Party of Japan. Komeito, which left the national coalition with the LDP, still recommended him at the prefectural chapter level. Prime Minister Sanae Takaichi's government is treating the race as a test of whether Tokyo can put a cooperative administration in Naha after twelve years of All Okinawa governors.

Koja was born in 1983, after reversion. He has put youth and child-rearing at the front of his campaign and has promised to raise prefectural income by expanding the use of returned base land and by pressing for a larger Okinawa promotion budget. Tamaki, born in 1959 under U.S. administration, points to record prefectural tax receipts and has proposed a fund for households in hardship. Inflation and wages have shared the stage with the bases.

Why Sunday's count will travel beyond Naha

This is the 15th gubernatorial election since Okinawa reverted to Japan in 1972. The last contest, in 2022, produced a turnout of 57.92 percent. Results are due the same night. The winner takes office as the national government continues work at Henoko and as the United States keeps the bulk of its Japan-based Marines on the island chain.

Futenma sits in a dense part of Ginowan. Accidents and noise around the field have driven local politics for three decades. A governor who refuses the landfill can slow permits and court fights. A governor who accepts it can accelerate both. That is the practical difference on the ballot, whatever the speeches say about income doubling or hardship funds.

The race also sits in front of unified local elections in spring 2027. Polls published in the final week described Tamaki and Koja as close, with the other four well behind. A conservative win would be the first since 2014. A Tamaki win would keep the prefecture on the same collision course with the defence ministry that has defined his two terms.

Stations close in the evening. The election board will report a trend once enough boxes are open. The number that matters is not the raw vote. It is whether the next governor signs, delays or fights the next set of Henoko papers that Tokyo already has on the desk.
