Russia has deployed the Bastion coastal missile system on Paramushir island, which is a part of an island chain called Kuril islands, stretching between the Japanese island of Hokkaido at its southern end and the Russian Kamchatka Peninsula at its northern end.
Before Vladimir Putin launched a full-scale invasion of Ukraine, he was actually planning to attack Japan, according to an alleged letter from a whistleblower at Russia’s Federal Security Service (FSB).
Tokyo is aggressively asserting its territorial claims to the Kuril Islands in its longstanding dispute with Moscow, while accusing China of preparing to invade Taiwan.
