Japanese Prime Minister Sanae Takaichi has formally moved to designate Osaka as a secondary capital to ensure governmental continuity during a catastrophic natural disaster. The proposal, a cornerstone of the ruling coalition’s legislative agenda, aims to establish an administrative backup capable of assuming control if Tokyo is incapacitated by a predicted major earthquake, according to government legislative reports.
Why is Japan planning a secondary capital?
The primary driver for the “second capital” initiative is the long-standing risk of a “megathrust” earthquake in the Nankai Trough or directly beneath the Tokyo metropolitan area. Seismologists have warned for years that a major seismic event could paralyze the nation’s political, economic, and administrative core, all of which are currently concentrated in Tokyo. By establishing Osaka as a functional duplicate, the government intends to maintain core state operations—including the parliament, key ministries, and the imperial court—within hours of a disaster. This strategy is designed to prevent the total administrative collapse that experts fear would follow a direct hit on the capital.
Japan’s current administrative structure is highly centralized. The proposed Osaka facility would be the first to legally mirror the 23 special wards of Tokyo, granting it unique status to manage national emergencies.
What is the status of the legislation?
The project is currently advancing through the Japanese parliament with a target completion date of July 17, 2026. Prime Minister Takaichi’s Liberal Democratic Party (LDP) is working closely with the Japan Innovation Party (JIP) to secure the necessary legislative support. The JIP, which maintains its political stronghold in the Kansai region and Osaka, views the proposal as a vital step in decentralizing Japanese governance. Recent negotiations between Prime Minister Takaichi and JIP leader Hirofumi Yoshimura resulted in the removal of a contentious clause regarding the administrative merger of Osaka, clearing a significant hurdle for the bill’s passage.
How will the backup infrastructure function?
According to the draft legislation, Osaka would receive a special legal status that allows it to operate as a functional twin to Tokyo. This involves creating an administrative framework capable of absorbing the duties of the central government during a crisis. Unlike previous disaster-preparedness plans, this initiative focuses on structural duplication rather than mere evacuation protocols. The goal is to provide a “hot-standby” government center that can transition into active service immediately following an emergency, ensuring that the decision-making apparatus of the state remains intact.
Comparison of Administrative Planning

| Legal Status | Capital City | Special Administrative Zone |
| Primary Goal | Daily Governance | Disaster Resilience |
Frequently Asked Questions
- Why was the Osaka merger clause removed?
The clause regarding the “Metropolis Osaka” merger faced strong opposition from the local wing of the LDP. To ensure the broader project could pass, the coalition agreed to remove it. - What triggers the use of the secondary capital?
The facility is specifically designed for deployment during large-scale natural disasters that render Tokyo’s infrastructure non-functional. - Is this the first time Japan has considered a second capital?
While discussions on decentralization have occurred for decades, this is the first time the initiative has been integrated as a key priority in a formal coalition agreement with a specific deadline.
Monitor the legislative sessions leading up to July 2026 for updates on the specific funding allocations for the Osaka infrastructure, as these will indicate the scale of the government’s commitment to the project.
