A bill related to the concept of a "sub-capital" that would serve as an alternative to the capital in the event of a large-scale disaster was voted on at the plenary session of the House of Representatives on the 15th, and was passed with a majority of votes from both the Liberal Democratic Party, the Ishin Party, and Team Mirai. The Centrist Reform Alliance, the Democratic Party of Japan, the Participating Parties, the Japanese Communist Party, and the Reiwa Shinsengumi opposed the move.
