Japan cries foul as Russia moves missiles into Kuril Islands
- Tokyo files protest with Moscow after it deploys battery of air-defence missiles on islands off Hokkaido
- The escalation in military tensions comes as Japan is already involved in bitter sovereignty disputes with China and South Korea

The battery of S-300V4 missiles was deployed on Iturup, one of the Southern Kuril archipelago. Japan refers to the island as Etorofu, part of the Northern Territories.
Russian television has broadcast images of exercises using the weapons system, which is designed to target enemy aircraft and inbound missiles, since it was installed. The missiles have an effective range of 400km.
“The deployment contributes to the Russian military build-up on the Northern Territories and conflicts with our country’s position that the islands are our inherent territory,” Chief Cabinet Secretary Katsunobu Kato said at a press conference in Tokyo on Wednesday.
There were some very significant differences between the three different disputes, said Toshimitsu Shigemura, a professor of international relations at Waseda University in Tokyo.
