ChainCatcher news, according to Jinshi reports, the Japanese House of Representatives and the House of Councillors will hold a prime ministerial nomination election. Since the ruling coalition formed by the Liberal Democratic Party and Komeito did not obtain a majority of seats in the previous House of Representatives election, this brings uncertainty to the upcoming prime ministerial nomination election.According to the rules and procedures, the prime ministerial nomination election is conducted in the order of the House of Representatives first, followed by the House of Councillors. The person who receives more than half of the valid votes in the first round of voting wins. Many Japanese media outlets predict that it may not be possible to directly determine the winner in the first round of voting in the House of Representatives.The decisive round of voting is expected to take place between Liberal Democratic Party President Shigeru Ishiba and the leader of the largest opposition party, the Constitutional Democratic Party, Yoshihiko Noda. In the decisive round of voting, the person with the highest number of votes wins. This will be the fifth time in Japanese history that the House of Representatives prime ministerial nomination election has entered a decisive round of voting.
