Yachi’s statement has angered many Japanese politicians. The country’s Minister of Foreign Affairs Hirofumi Nakasone said that the official position on the issue hasn’t changed and they are demanding the return of all the islands. Prime Minister Taro Aso also stressed the fact that Yachi was just expressing his own opinion.

Following the harsh criticism, Former Administrative Vice-Minister for Foreign Affairs had to explain that the newspaper has misinterpreted his words. However, three years ago Taro Aso himself, who was minister of Foreign Affairs then, mentioned possible options of dividing the islands in half judging by the territory each of them occupies. Later he insisted he was misunderstood.

The disputed islands issue has been paid much attention by both sides recently. At a summit meeting held between the two countries in Sakhalin, the easternmost island in Russia, on February 18, Prime Minister Taro Aso and Russian President Dmitry Medvedev agreed to speed up efforts to resolve the issue of the Northern Territories under a “new, original and non-standard approach.”

Yachi has been a trusted Aso advisor since his days as administrative vice-minister for foreign affairs and accompanied the prime minister on his February trip to Russia.

Why compromise now?

According to Sergey Luzyanin, an expert on oriental studies from MGIMO University, considers this to be a step back towards the policies Japan acted upon in the 1950’s:

“In 1956 the so-called Russian-Japanese declaration identified a new approach to resolving the territorial dispute. The Japanese government, together with Nikita Kushchev decided then that the Soviet Union would give up part of the Kurill islands as a gift for the Japanese side upon signing a mutual declaration of friendship”.

The declaration was never side and the negotiations froze. However, according to Luzyanin, due to mutual interests which tie Russia and Japan together, which push the poignant issue of the disputed territories towards compromise.

First of all, Japan is interested in maintaining a trading and economic partnership with Russia, especially in the light of the global financial crisis.

Secondly, in terms of geopolitical partnership, Japan could be interested in forming a stronger union to balance out the growing importance of China.

Thirdly, it is demonstrative of Japan’s desire to independently resolve its disputes with Russia, without the involvement of the U.S. and global international political players.

All this, according to Luzyanin, could lead to further progress and compromise within the Kurill issues. However, he points out that this territorial dispute is only one of many unresolved questions which separate Russia and Japan from full-scale co-operation.
