The Japanese government, in a recent policy shift, has opened up the possibility of establishing a sub-capital in multiple locations. The move comes as part of wider local revitalization efforts aimed at moving away from Tokyo-centric administrative structures. Specific locations have not been announced yet, but the government's decision has spurred an enthusiastic response from various prefectures bracing for strategic socio-economic development.

Japan's administrative structure has been largely Tokyo-centric, which has led to overpopulation and economic saturation in the capital. Decentralization efforts such as the sub-capital plan are critical for balanced regional development. The Japanese public is largely supportive of this, viewing it as an opportunity for regional revitalization and a chance to alleviate the administrative burden on Tokyo.

The U.S. might handle a similar issue by decentralizing federal agencies across different states. In the E.U., Brussels and Strasbourg share major institutional bodies to ensure balanced development. Thus, Japan's strategy mirrors global efforts in decentralization and regional equity.
