Japan's Prime Minister vows to stay on after election defeat

TOKYO,  Japan

Japanese Prime Minister Shigeru Ishiba's ruling coalition has failed to secure a majority in Sunday's election for the 248-seat upper house of parliament, Japan's public NHK TV outlet said.

The Liberal Democratic Party (LDP), already in a minority in the lower house since last October's snap election, faced mounting public discontent over inflation, political scandals, and a surge in anti-immigration sentiment.

The LDP and its junior partner Komeito needed to win 50 of the 125 contested seats, on top of the 75 seats they already have. 

They fell short, however, getting only 46 of the seats up for grabs. 

In recent years, such an electoral defeat has usually led to a prime minister's resignation. 

Ishiba, however, vowed to stay on in order to lead Japan through the difficult terrain of striking a trade deal with the US in the face of looming tariffs.

"We are engaged in extremely critical tariff negotiations with the United States...we must never ruin these negotiations," he told a press conference after vowing to stay on as party leader through the trade talks.

The loss is another blow to Ishiba's coalition, making it a minority in both houses following its October defeat in the lower house election.

It is the first time the LDP has lost a majority in both houses of parliament since the party's foundation in 1955.

The poor performance in the election will not immediately trigger a change of government because the upper house lacks the power to file a no-confidence motion against a leader. 

Despite his determination to stay on, Ishiba could face calls from within his party to step down or find another coalition partner.
