Overview
- President Vladimir Putin traveled to the island of Iturup on Thursday, August 13, 2026, after attending Pacific Fleet exercises and was shown visiting a fish‑processing plant, a hospital and a school in footage released by the Kremlin.
- Tokyo responded by summoning Russia’s ambassador Nikolai Nozdriev and filing a formal, “energetic” protest through Foreign Minister Toshimitsu Motegi while Prime Minister Sanae Takaichi called the visit “absolutely unacceptable.”
- The Russian government defended the trip, with Kremlin statements and Foreign Ministry spokeswoman Maria Zakharova rejecting Japan’s complaints as legally unfounded and framing the visit as an affirmation of Russian sovereignty based on post‑World War II arrangements.
- No military clash has been reported, but the visit further narrows diplomatic space for a treaty because Russia’s 2020 constitutional ban on ceding territory and Tokyo’s 2022 sanctions have already frozen substantive negotiations, and international bodies including the EU and UN urged restraint.
- The dispute concerns four southern Kuril islands claimed by Japan and administered by Russia since 1945, home to about 20,000 Russian residents and valuable fishing and mineral resources, making the visit both symbolic for domestic audiences and consequential for regional security and local livelihoods.
