Diplomatic Crisis: Tokyo Demands Protest After Putin's Visit to Iturup

On August 13, 2026, diplomatic relations between Russia and Japan reached a critical point. Japanese Prime Minister Sanae Takaichi made a sharp statement condemning the visit of Russian leader Vladimir Putin to the island of Iturup. In her address, Takaichi emphasized that the island is an integral part of Japan, and the Russian Prime Minister's trip to this territory is a gross violation of Tokyo's sovereignty. According to the head of the Japanese government, Moscow's actions are "incompatible with Japan's consistent position" and pose a threat to international law.

Official Protest and Summons of Ambassador

In response to the visit by the Russian leader, the Ministry of Foreign Affairs of Japan initiated emergency diplomatic procedures. The Russian Ambassador to Japan, Nikolai Nozdrev, was urgently summoned to the country's MFA to receive a note of protest. Japanese Foreign Minister Toshimitsu Motegi personally met with the Russian diplomat, urging him to convey Tokyo's firm protest to the leadership of the RF. According to sources, Nozdrev, answering journalists' questions in Japanese, refrained from commenting, which only heightened the tension in the diplomatic corridor.

Historical Context and Legal Arguments

In her statement, Sanae Takaichi did not limit herself to merely condemning the visit but also returned to the roots of the territorial dispute. She reminded that the chain of islands, including Iturup, Kunashir, Shikotan, and the Habomai group, was, in Tokyo's view, illegally seized by the Soviet Union at the end of World War II. The Japanese leadership insists that these territories were never transferred to the USSR by a peace treaty, and their occupation is illegal. At the same time, the Russian side traditionally refutes these claims, citing the outcome of the war and subsequent international agreements.

Contradictory Data

The question of the status of the Kuril Islands remains one of the most acute in modern geopolitics, with the parties holding diametrically opposite points of view. Japan officially considers Iturup and other islands its "Northern Territories," illegally occupied by Russia. In turn, Moscow insists that these islands were legally incorporated into the USSR in 1945 and are an integral part of the Russian Federation. Putin's visit to Iturup, which Tokyo calls "uncoordinated," is viewed by Moscow as a visit to its own territory, making the summons of the ambassador to the Japanese MFA, in the opinion of Russian diplomats, an unfounded demarche.

Consequences for the Peace Treaty

The escalation of the conflict around Iturup once again threatens the possibility of concluding a peace treaty between the two countries. Sanae Takaichi emphasized that the dispute over the ownership of the islands remains the main reason why Russia and Japan have not yet formally ended the state of war that arose during World War II. The visit of the Russian leader to the disputed territory, in the opinion of the Japanese side, demonstrates Moscow's lack of political will to resolve the issue. This could lead to further cooling of relations and freezing of any negotiations for an indefinite period.
