Denny Tamaki leads trader pricing in the September 13, 2026 Okinawa gubernatorial election at 66.5 percent implied probability as the two-term incumbent backed by the “All Okinawa” coalition. His consistent opposition to relocating U.S. Marine Corps Air Station Futenma to Henoko remains the central campaign issue, reinforced by his August 12 policy announcement emphasizing local dialogue with Tokyo and economic priorities. The Liberal Democratic Party’s selection of Genta Koja as challenger at 27.5 percent reflects post-February 2026 national election shifts that weakened the prefectural opposition bloc and introduced coalition uncertainty around base policy. Lower odds for other listed candidates align with limited organized support and the race’s effective two-way structure heading into the final campaign month.
