Japan secondary capital race expands with regional alliances

Overview

In late July 2026, Japan’s Diet passed a law establishing a “sub‑capital” framework to decentralize functions from Tokyo and provide a disaster backup. The legislation, which passed the upper house by a narrow 123-121 vote, addresses a roughly 70% chance of a magnitude-7 earthquake striking the Tokyo area within 30 years. The law aims to ensure governance continuity during disasters while providing tax incentives and new facilities to the chosen region.

Osaka Prefecture quickly announced its intention to apply, with Governor Yoshimura Hirofumi advocating an “Osaka Metropolis” model to reorganize the city into special wards. Within days, Gunma and Kyoto prefectures joined the contest, citing low disaster risk and historical precedent. In mid-August, Hokkaido and Sapporo announced a joint proposal, with Governor Naomichi Suzuki noting the region’s geographic distance from Tokyo poses an “extremely low risk of simultaneous disaster.” Sapporo Mayor Katsuhiro Akimoto added that the city possesses the necessary functions to serve as an ideal location.

By late August, the competition intensified through unexpected regional alliances. Hokkaido Governor Naomichi Suzuki and Osaka Prefecture Governor Hirofumi Yoshimura signed a cooperation agreement to jointly pursue designation as “sub-capitals.” This marks the first instance of two prefectures entering such an agreement to work toward the goal. The leaders discussed transitioning toward a “multi-polar, decentralized economic zone” and are considering making joint appeals to the national government to secure simultaneous designation.

While proponents highlight urban revival and disaster preparedness, opponents have criticized the plan as a political maneuver intended to benefit allies of Prime Minister Sanae Takaichi. Critics have called for clear criteria that prioritize geological stability and disaster resilience over regional political interests.
