A total of 315 people as of Wednesday are preparing to run in this summer's election for the House of Councilors, the upper chamber of parliament, according to a survey by Jiji Press.
The focus will be on whether Prime Minister Shigeru Ishiba's ruling coalition will secure an Upper House majority of 125 seats, including seats that are not up for grabs in the upcoming race.
