During a rally commemorating Northern Territories Day, Japanese Prime Minister Sanae Takaichi highlighted the long-standing issue of not having a peace treaty with Russia to formally conclude the hostilities of World War II. She described the situation as 'really vexing and regrettable', emphasizing Japan's ongoing claims over the Kuril Islands, which are regarded by Russia as part of its sovereign territory following their incorporation into the Soviet Union in 1945.

The Kuril Islands dispute has persisted for decades, centered on the southernmost islands of the archipelago, which Japan refers to as the 'Northern Territories'. This historical conflict represents not only a territorial claim but also an important aspect of national identity for Japan. Takaichi's comments reflect a renewed focus on the issue, calling for dialogue and negotiations to address the longstanding tensions.

Takaichi's remarks come amidst broader geopolitical dynamics in the region, where Japan seeks to maintain its national interests while navigating diplomatic relations with Russia. The absence of a peace treaty has implications for both countries' security and diplomatic engagements in the Asia-Pacific region, marking a critical point in their post-war relations and territorial integrity discussions.
