Japanese lawmakers are currently debating a bill to establish a secondary capital to distribute key political, economic, and administrative functions outside Tokyo [1, 2].

The proposal aims to create a critical backup for government operations during disasters and correct the extreme concentration of population and wealth in the Tokyo metropolitan area [1, 3].

The ruling coalition, consisting of the Liberal Democratic Party and the Japan Innovation Party, is pushing the legislation forward during a parliamentary session that has been extended through July 25 [1, 2]. Mitsuki Takayanagi of TBS NEWS DIG said the concept focuses on granting important functions to regions other than the current capital [1].

Opposition parties have criticized the bill, describing it as a contract without a blueprint. Some critics argue that the government has already implicitly decided on Osaka as the location, despite official claims that no specific site has been chosen [1, 4].

Takahito Aoki of the TBS News Department political bureau said the ruling party is primarily considering two main scenarios [1]. While the official position remains that the location is undecided, the tension between the government's desire for flexibility and the opposition's demand for transparency continues to stall the proceedings [1, 4].

Separate from the capital debate, the current session is also addressing the House of Representatives seat reduction bill, which proposes a cut of 45 seats [5].

The concept focuses on granting important functions to regions other than the current capital.

The push for a secondary capital represents a strategic shift in Japan's national security and urban planning. By decentralizing power, Japan seeks to mitigate the risk of a total government collapse during a major earthquake in Tokyo, while simultaneously attempting to revitalize regional economies that have suffered from decades of urban migration.
