Japan to hold Upper House election on July 10

Japan's Cabinet has decided to schedule an Upper House election for July 10.

Half of the seats come up for grabs every three years in the upper chamber, where members have six-year terms.

In the upcoming election, 125 seats will be contested -- 74 in prefectural constituencies, one to fill a vacancy in Kanagawa Prefecture and 50 under the proportional representation system.

Campaigning will officially kick off on Wednesday, June 22. The main issues are likely to be the country's economic measures, diplomacy, security and social welfare.

Japan's Upper House will have 248 seats in total, three more than in the previous election, with 148 seats allocated to constituencies and 100 to proportional representation.
