Japan's recent passage of the secondary capital Bill on July 24 marks a significant step in addressing the country's vulnerability to earthquakes. The legislation allows the Prime Minister to designate a prefecture to handle government functions if Tokyo is incapacitated by a disaster.

Osaka is currently viewed as a frontrunner for this designation, as discussions around decentralizing Tokyo's dominance in governance gain momentum.6

The Bill was narrowly approved by the National Diet, with a vote of 123 in favor and 121 against, reflecting the urgency of enhancing national resilience.7

Japan experiences an average of 2-3 earthquakes daily, with over 1,500 recorded in a year, due to its location at the intersection of four tectonic plates. The government estimates a 70% chance of a major earthquake occurring in the Tokyo area within the next 30 years.5

The Act stipulates that selected prefectures must have adequate infrastructure and population to function effectively as a secondary capital. Additionally, it mandates the central government to develop transport facilities and promote economic deregulation to attract private investment.

Other regions like Fukuoka, Hokkaido, and Miyagi are also in consideration, but the focus remains on Osaka as the potential secondary capital, highlighting the need for a robust framework to ensure continuity of national functions during disasters.
