In an escalating territorial disagreement, Russia has reacted strongly to Japan's decision to rectify maps showing the disputed islands, known as the Northern Territories in Japan, as Russian-controlled. The territories, viewed from Japan's perspective, are showing the changes that were made without their approval, leading to this diplomatic ripple. The issue dates back to post-World War II and remains an unresolved matter between the two countries.

In Japan, the Northern Territories dispute is a deeply emotional issue that stirs up nationalistic feelings. Resolving it is seen as a matter of national pride. Most Japanese citizens express strong support for the government's stance on the issue, which maintains that the territories are an inherent part of Japan. Furthermore, the issue is tied to Japan's relations with Russia, affecting diplomacy and trade.

This issue can be somewhat compared to the territorial disputes in the US or EU, albeit very few in modern times, but the intensity of such conflicts and the diplomatic tension they create are indeed comparable. The US and EU have also had historical territorial disputes, with the occupation of territories after the war often remaining contentious. However, their approach is more grounded in diplomacy, international law, and multilateral negotiations.
