Japan in September 2026: the most important developments in politics
In September 2026, Japanese politics centred on the Okinawa governor's election and Prime Minister Sanae Takaichi's reshuffle of her party and cabinet. Genta Koja, backed by the ruling LDP, won the Okinawa governorship by a wide margin in mid-September. He supports relocating the US Futenma air base to Henoko and called for a clearer timeline for Futenma's return. Takaichi said she would work closely with him on economic issues, and the government spoke of promoting a "Nansei shift" after the vote. Incumbent Governor Denny Tamaki stepped down on September 29. Turnout at the end of voting day was 29.65% by 7:30 pm, above the previous race, and warnings were issued about AI-generated misinformation on social media during the campaign.
Takaichi reshuffled LDP executives on September 16 and the cabinet the next day, keeping most key executives and the economy minister, which signalled no change in spending plans. A survey released on September 20 put her approval at 62 percent. Among the opposition, the Democratic Party for the People re-elected Yuichiro Tamaki as leader on September 6 for a third term. On September 9 opposition parties moved to divide contested districts and coordinate candidates after merger talks failed, and a new party was reported at zero percent support in its early phase.
Foreign policy was dominated by relations with the United States, China and Russia. Takaichi met President Trump on September 22 at the UN, ahead of the US-China summit that began on September 24, and the two sides reaffirmed the alliance. In her first UN General Assembly speech on September 23 she called for the removal of the wartime "enemy state" label from the UN Charter and for Security Council reform; China's foreign minister rejected this and said the clauses remain relevant. China repeatedly urged Japan to correct Takaichi's stance on Taiwan, and warned against what it called militarism and historical denialism in Japan. Japan sought a change to a new UN world map over the Northern Territories, and asked Russia to remove a statue; Russia called for removal of US Typhon missile systems and said relations continue to deteriorate.
Domestically, Tokyo wards including Shinjuku and Taito moved to restrict short-term rentals. A Tokyo court ruled that AI cloning of an actor's voice violated his rights, and another ruled that a blanket ban on election campaigning by minors is unconstitutional. Japan said progress was made on a $550 billion investment pact with the United States and pledged $3 million to flood-hit Nepal.
