National Museum of Territory and Sovereignty

The National Museum of Territory and Sovereignty is located on the first floor of Toranomon Mitsui Building and presents exhibitions about Japan's geographic and territorial matters. The galleries contain maps, written documents, and informational panels that address various regions and their historical connections.

The museum was founded in January 2018 and relocated to its current location two years later. This move significantly expanded the exhibition space and allowed for a broader presentation of documents and materials.

The exhibits present materials related to areas that shape Japan's geographic identity and are displayed in multiple languages. Visitors encounter documents and visual displays that reflect how territorial questions are understood locally.

The museum is easy to reach by public transport and offers free admission. Weekdays are the best time to visit when fewer people are present and you can view the exhibits at a relaxed pace.

An interactive section allows visitors to engage with territorial documents and maps through computer-based systems. This technological approach makes the information more accessible and enables deeper exploration.
