The Democratic Party of Japan-led ruling coalition passed bills and treaties at several House of Representatives committee sessions Friday that were boycotted by two opposition parties.
The bills and treaties included one on compensation for people who suffer side effects from vaccinations for H1N1 and another to revise a law regulating payments and allowances for court judges.
The Liberal Democratic Party and its smaller ex-ruling bloc partner New Komeito boycotted all of the committee votes.
The DPJ, which holds 308 of the 480 seats in the powerful lower chamber, aims to get through the bills and treaties in plenary sessions next week.
The committee votes came just after the Lower House early Friday passed a bill to encourage lenders to freeze debt repayments by small and midsize companies as the ruling parties forced a vote, increasing tension with the opposition camp.
In the morning, Prime Minister Yukio Hatoyama criticized the opposition parties for refusing to participate in Diet deliberations.
"Neither of us (the ruling or opposition camps) should do something like boycotting Diet proceedings," he told reporters.
