The parliament opened a 24-day extraordinary session on Thursday as Prime Minister Shigeru Ishiba seeks to enact political reform legislation and a supplementary budget.

He is expected to face intensified pressure from opposition parties after his ruling coalition lost its majority in the powerful House of Representatives in an election last month.

Ishiba, who took office in October, will deliver a policy speech in both parliamentary chambers on Friday, followed by question-and-answer sessions from Monday through Wednesday.
