Japan is eager to send tourists to the disputed islands for a pilot trip. Why was it suddenly postponed by Russia?

Recently, both Japanese and Russian media reported that the pilot tour of Japanese tourists to the South Kuril Islands, originally scheduled for October 11th to 16th, has been postponed, which may need to be postponed to the end of October or early November. On the other hand, Japan expressed its desire to actively promote the economic and peace treaty of the South Kuril Islands, and has made a lot of efforts with the Russian side at the diplomatic level to actively attract tourists to the South Thousand Islands, but the Russian side decided to postpone it.

So why is Japan in such a hurry to send Japanese tourists to the controversial Nanqian Island for a pilot tour? But also rejected by Russia. In fact, Russia's rejection of Japan is foreseeable, which has a lot to do with things a long time ago. Kuril Islands is located between kamchatka peninsula in the Russian Far East and Hokkaido in Japan, among which Sedan, Queen of the Country, Tooth Dance and Selective Catch are called South Kuril Islands by Russia.

These islands actually belonged to Japan before World War II, but they were occupied by the Soviet Union after World War II, and they were controlled by Russia after the disintegration of the Soviet Union. Russia did not sign a peace treaty with Japan after World War II. In 1855, Japan signed a treaty with Russia, demanding the return of the four islands in the South Kuril Islands, and made the return of these four islands a condition for signing a peace treaty with Russia.

So from the standpoint of Russia, Nanqian Island is Russia's, and Russia has undeniable sovereignty over Nanqian Island. At this time, if Japan wants to find a way to take this South Kuril Islands, it is really a long way to go, so don't worry too much and take your time.
