On the 21st local time, the House of Representatives and Senate of Japan will hold elections named by the Prime Minister. Given that the Liberal Democratic Party and the Japan Reform Council have reached an agreement on joint governance, and that the opposition parties have not formed a unified candidate, it is likely that the Liberal Democratic Party President Saharami Takashi will become Japan's new prime minister and form a cabinet.

In accordance with the relevant regulations, in the elections for the nomination of the Prime Minister, parliamentarians can cast blank votes. If no candidate obtains a majority of the total votes, including blank votes, the winning rounds will be held by the first two. In addition, according to the relevant laws of Japan, although in principle the Senate and the House of Representatives have equal powers, the House of Representatives has the priority to decide on legislation, the appointment of the Prime Minister, and so on.
