On January 12, the ruling party and government confirmed their plan to pass the 2026 budget proposal through the House of Representatives by holding a vote in the Budget Committee on January 13. Chairman Tetsushi Sakamoto of the Budget Committee, from the ruling Liberal Democratic Party (LDP), pushed through the decision to conclude discussions and conduct the vote, regardless of the objections raised by opposition parties. The ruling party is strongly advocating for the budget's passage within the current fiscal year, which has led to significant reductions in discussion time.

During a Budget Committee meeting on January 12, the ruling coalition proposed concluding discussions and holding the vote on January 13. The opposition, consisting of various parties including the Constitutional Democratic Party and the Japanese Communist Party, expressed strong dissent and even submitted a resolution for Sakamoto's dismissal. Despite their efforts, the resolution is expected to be rejected during the session on January 13, with the ruling party determined to proceed with the budget vote.

The new fiscal year's budget proposal typically undergoes about a month of scrutiny in both houses of the Diet, but this year has seen delays due to the Prime Minister's dissolution of the House of Representatives at the beginning of the regular session in January. Actual discussions have only started in late February, and while the ruling party aims to pass the budget in the House and move to the Senate by January 16, the opposition holds a majority in the Senate, making it uncertain whether the ruling party's agenda will be successfully carried out as planned.
