With less than a month left in the parliamentary session, Prime Minister Sanae Takaichi is accelerating efforts to pass key legislation, pushing forward controversial policies that include a revision of the Imperial Household succession law, a reduction in the number of parliamentary seats and a backup capital plan that is a key goal for the ruling Liberal Democratic Party¡¯s coalition partner.

Takaichi and Japan Innovation Party (JIP) head Hirofumi Yoshimura agreed Monday to work to have the backup capital bill passed by the end of the parliamentary session on July 17.

¡°This initiative is framed as a secondary capital plan that encompasses the Osaka merger plan,¡± Takaichi told reporters after the meeting,

¡°It¡¯s a truly unprecedented reform of the nation¡¯s governance structure. It¡¯s immensely significant for enhancing national resilience for establishing an economic hub outside the Tokyo metropolitan area,¡± the prime minister added.

The plan has long been sought by the JIP, also known as Nippon Ishin no Kai, which agreed to join the LDP ruling coalition last year in exchange for passing legislation in the 2026 regular session of parliament that establishes a secondary capital that would take over Tokyo¡¯s functions in the event of a disaster and also help decentralize the capital¡¯s functions.

Takaichi and Yoshimura must now convince members of their own parties to accept the bill. But with less than a month remaining and other legislation still pending, it¡¯s unclear as to whether sufficient time remains to debate what remains a controversial measure.

Their meeting was followed Tuesday by the LPD¡¯s approval of a bill establishing a secondary capital as a backup to Tokyo in the event of an emergency. But following the Takaichi and Yoshimura meeting Monday, the bill now lacks a clause allowing for an Osaka city merger referendum to be voted on by all of Osaka Prefecture.

The Osaka-centric JIP had long sought passage with the clause intact. It wanted to expand the eligible voters to all of Osaka Prefecture in the hope of securing approval for its merger plan. Some legal scholars warned that allowing non-city residents to vote on a city merger may violate Article 92 of the Constitution, which guarantees local autonomy.

The backup plan also faced opposition from many within the LDP because it would entail abolishing the current structure of Osaka city and reorganizing it into more autonomous wards, along the lines of Tokyo, through a local referendum, meaning the end of the current city assembly.

In separate remarks to the media Monday, Yoshimura said he and the prime minister agreed the merger plan was highly significant and that the provision that would expand the Osaka merger referendum to prefectural voters outside city limits was...
