TOKYO - Japanese Prime Minister Shigeru Ishiba on Thursday ruled out dissolving the House of Representatives for now, ensuring that elections for both chambers of parliament will not take place on the same day in July, Kyodo News reported.

The decision came as Yoshihiko Noda, leader of the main opposition Constitutional Democratic Party of Japan, said he will not submit a no-confidence motion against Ishiba's cabinet.

After talks with Noda, Seiji Maehara, co-head of the opposition Japan Innovation Party, quoted him as saying that a political vacuum should be avoided amid concerns over higher US tariffs and intensifying tensions in the Middle East, the report said.

Ishiba has previously expressed readiness to dissolve the powerful lower house for a snap election if Noda's party submits a no-confidence motion during the ordinary Diet (parliament) session.

With criticism growing that postponing the no-confidence motion showed weakness, Noda said at a press conference later in the day, "This is about crisis management," adding, "It is not about appearing fragile, but about acting responsibly," the report said.

Noda's party is the only opposition force with the numbers to independently submit such a motion, but it would need support from others for it to pass. Some parties have been reluctant to face a general election as they are not fully prepared.

The ruling coalition led by Ishiba's Liberal Democratic Party currently lacks a majority in the lower house. A no-confidence motion, if passed, would require the prime minister to dissolve the 465-member chamber or the cabinet to resign en masse within 10 days.

Meanwhile, the election for the House of Councillors, or upper house, is expected to be held on July 20, following the end of the current 150-day regular parliamentary session on June 22.
