The corresponding statement was published on the official website of the Russian Foreign Ministry.
"Such actions, carried out with the connivance of the Japanese authorities, once again testify to the reluctance of official Tokyo and a number of political and social forces of the country to look directly into the eyes of history and draw the proper lessons from it," the publication says.
The Russian Foreign Ministry expressed serious concern about Japan's attempts to ignore the recognized results of World War II and its unwillingness to give an objective assessment of the country's past.
According to TASS, several dozen people are taking part in the action near the Russian embassy in Tokyo in at least 10 cars with ultra-right slogans written on the bodies.
Demonstrators make calls for the Kuril Islands.
The Russian authorities have repeatedly spoken about the indisputability of Russia's sovereignty over the Kuriles.
