Tokyo is ready to offer Moscow to sign a corresponding document along with a peace treaty, the newspaper Yomiuri Shimbun reported, citing informed sources.
Now, the Japanese government is considering paying the islands' former residents compensation for the damage suffered at the treasury's expense, without demanding compensation from Russia, the newspaper said.
Additionally, the publication did not specify what the compensation claims from the Russian side could be.
In 1956, the two sides signed a Joint Declaration that provided for the restoration of bilateral relations after the war and stipulated that Japan and the Soviet Union would continue to make efforts toward signing a permanent peace treaty and settling the dispute over the islands.
On November 14, Russian President Vladimir Putin and Japanese Prime Minister Shinzo Abe agreed to advance negotiations on a peace treaty based on the 1956 Soviet-Japanese joint declaration, the only document recognised by both countries. This is a serious concession on the part of Japan, since Tokyo's official position previously was to demand the return of the four islands prior to the conclusion of a peace treaty.
