This is stated in a message published on the website of the Russian Foreign Ministry.

The Foreign Ministry reported that during the conversation, the Japanese diplomat drew attention to the opening in Tokyo on January 21 with the support of the country's authorities a permanent exhibition “Territory and Sovereignty”, “including propaganda materials allegedly demonstrating the validity of Japan’s territorial claims to the southern Kuril Islands”.

It is noted that the department pointed to the indisputability of the legitimate sovereignty of Russia over this territory.

The Foreign Ministry emphasized that such actions by the Japanese side are contrary to the agreement of the leaders of Russia and Japan on creating a positive atmosphere in bilateral relations.

"We see in this also another evidence of the unwillingness of the Japanese partners to fully recognize the results of the Second World War," the report said.

In December, the leader of the Communist Party of Japan, Kazuo Shi, called for the declaration of all the Kuril Islands as part of Japan.

State Duma Speaker Vyacheslav Volodin responded to this call, stressing that such statements "undermine the confidence of countries in each other."
