Japan’s upper house is set to hold the final vote on bills to expand the role of the country’s military abroad.
The changes will allow Japanese troops to fight overseas for the first time since World War Two.
They are expected to pass, despite public protests, as Prime Minister Shinzo Abe’s ruling coalition controls the House of Councillors.
Politicians have first been voting on opposition censure motions brought in an attempt to delay the bills’ passage.
The opposition also plan to file a no-confidence vote in the lower house and may even try walking at an extremely slow pace to some ballots, to use up as much time as possible.
On Thursday, opposition politicians tried to physically delay proceedings ahead of a committee vote on the bills.
