- Sanae Takaichi called Putin's visit to the disputed Kuril Islands 'absolutely unacceptable,' saying the islands are Japan's both 'historically and under international law' and calling the trip 'incompatible with Japan's consistent position.'
- Japan's Foreign Minister Toshimitsu Motegi summoned Russian ambassador Nikolay Nozdrev in protest, the most pointed diplomatic step Tokyo has taken in response to Putin's actions on the disputed chain.
- Vladimir Putin made his first visit to the islands — touring Etorofu (Iturup) and inspecting navy drills on nearby Sakhalin — and declared the four disputed islands 'recognised as Russian in international documents,' framing Japan as the party making territorial claims against Russia.
- Putin called Japan's recent sanctions 'unprovoked' and said Tokyo has 'identified Russia as a major source of threats' while 'we are not threatening Japan,' sharpening the rhetorical standoff.
- The Kuril dispute dates to August 1945, when the Soviet Union declared war on Japan in the closing days of WWII and seized the islands; about 17,000 Japanese were deported and roughly 20,000 Russian citizens now live there.
- The four islands — Etorofu, Kunashiri, Shikotan and the Habomai islet group, just off Hokkaido — offer rich fishing grounds and mineral deposits alongside their strategic value, and have blocked a formal Japan–Russia peace treaty for decades.
- Late PM Shinzo Abe's entente with Putin — including resumed visits by former Japanese residents to family graves — collapsed after Japan's 2022 sanctions on Russia over the Ukraine invasion, leaving bilateral relations at a post-war low.
Why it matters: With Putin personally touring the islands and declaring them Russian in international law, the Kuril dispute — frozen for years under Abe's diplomacy — is now actively re-escalated. Takaichi's unusually sharp language and the summoning of Russia's ambassador signal Tokyo is closing off any near-term path to a peace treaty, while Japan's alignment with Western sanctions on Moscow over Ukraine keeps it firmly in the anti-Kremlin camp on this second front.
