The Japanese government is reportedly considering the creation of a new ministerial post to oversee the development of a "secondary capital". This initiative appears to be a part of ongoing efforts to decentralize power from Tokyo and distribute it more evenly across the country. Specifics about the location and timetable for implementing this plan are yet to be disclosed.

In Japan, there has been a long-standing concern about the overcentralization of power in Tokyo. This has led to significant regional disparities and issues such as population decline in rural areas. The plan to create a second capital is seen as a potential solution to these problems.

In contrast to the US or EU, where power is distributed among various states or countries respectively, Japan has been traditionally centralized with Tokyo holding the majority of power. The issue of decentralization is thus unique to Japan, comparatively less discussed in contexts like the U.S or EU.
