South Korea has recently expressed opposition to the expansion of Japan's 'Territory Pavilion'. This museum, which supports Japan's territorial claims, has sparked controversy between the two East Asian nations. The matter, which remains unresolved, has led to heightened tensions and disputes. The South Korean government has not disclosed how they plan to respond.

Within Japan, territorial disputes such as this one carry historical and nationalistic significance. The issue of the 'Territory Pavilion' is a key example of this. The museum asserts Japan's territorial claims, which are deeply contested by neighboring countries like South Korea. For many Japanese citizens, these disputes relate to national pride and identity.

Territorial disputes are common globally, though the manner of handling them varies widely. In the US or EU, similar issues might be addressed through diplomatic negotiation and recourse to international courts or treaties. The use of museums or similar institutions to assert claims, as seen in Japan, is not as prevalent in the US or EU.
