The arrival of Japanese tourists on the Southern Kuril Islands, which are held by Russia but claimed by Japan, represents a significant development in the countries' long-standing territorial dispute.

In general, little ever seems to change in Japan's dispute with Russia. For seven decades, Japanese governments have claimed that, in the final days of the second world war, the Soviet Union illegally occupied the four islands off the northeast coast of Hokkaido.
