Putin Visits Japan‑Claimed Iturup, Prompting Tokyo Protest

Tokyo has summoned Russia’s ambassador and is weighing diplomatic and economic responses to Moscow’s reassertion of control.

Overview

  • President Vladimir Putin visited Iturup on Thursday, August 13, 2026, touring a fish‑processing plant, a hospital and a school and meeting regional officials and residents.
  • Japan lodged a formal protest through Foreign Minister Toshimitsu Motegi, Prime Minister Sanae Takaichi called the trip “absolutely unacceptable,” and Tokyo summoned Russia’s ambassador while officials discuss possible measures including tougher sanctions or a temporary ambassadorial recall.
  • The trip followed large Pacific Fleet naval exercises that Putin observed and came a day after North Korea fired a ballistic missile, raising regional security concerns about Moscow’s posture in the North Pacific.
  • Moscow presented the visit as a routine assertion of sovereignty and local support, and independent reporting notes Russia has in recent years expanded military infrastructure on the Kurils, including coastal defenses and air assets.
  • The visit revives the long‑running dispute that has blocked a formal post‑World War II peace treaty between Russia and Japan and could complicate trade and energy links Tokyo must weigh when deciding any reciprocal steps.
