Japanese voters will be able to trigger political turmoil as they go to the polls on Sunday, in an election to the High House of Parliament, which will be widely disputed, with the increase in prices and concerns about immigration threatening to weaken the control of Prime Minister Shigeru Ishiba over power.
Opinion polls suggest that Ishiba’s Democratic Liberal Party (PLD) and its coalition partner, Komeito, may fall short of the 50 seats needed to maintain control of the Parliament High House, which has 248 seats, in an election where half of the seats are in dispute.

As the worst PLD result in 15 years, the result stirred the financial markets and left the prime minister vulnerable to motions of distrust that can overthrow his government and provoke a new overall election.
Government governed by PLD for most of the postwar period, Japan has so far avoided the social division and fragmentation of politics observed in other industrialized democracies.
The vote ends at 8 pm (local time, 8 am on Sunday in Brasilia), when local media are expected to project results based on the river-mouth research.
