Moscow says it rejects Japanese protests over the country's military deployments on the disputed island territories.
Such moves damage bilateral ties, hinder their development, according to the Russian Foreign Ministry.
"We firmly reject such demarches, since Russia has the sovereign right to any activity on its territory, including measures to strengthen national defense. These actions are in no way directed against neighboring states and are exclusively an internal affair of our country," the statement says.
The ministry is convinced that any concerns that arise should not be removed with the help of "ritual protests", but through the existing mechanisms for bilateral dialogue on confidence-building measures in the field of security.
The islands of Habomai, Shikotan, Iturup and Kunashir are claimed both by Russia and Japan and remain the subject of a long-standing dispute between the countries. It has prevented the two sides from signing a permanent peace treaty after World War II, despite the fact that over 70 years have passed since the end of the conflict.
