The agreement between Prime Minister Sanae Takaichi and Japan Innovation Party (JIP) leader Hirofumi Yoshimura on revisions to a bill establishing a backup capital is a step toward fulfilling an October 2025 pact between the Liberal Democratic Party and the JIP. That deal gave LDP President Takaichi the needed votes to become prime minister and form a ruling coalition.

The parties submitted the bill to parliament Wednesday evening.

With the move, Takaichi has signaled she will continue to listen closely to the JIP, also known as Nippon Ishin no Kai, despite concerns within her own party over not only the backup capital concept, but also other controversial bills pushed by Yoshimura and his party that the LDP agreed to, including one to slash the number of seats in the lower chamber by 10%.
