Five opposition parties met with Speaker Eisuke Mori on Tuesday to demand the withdrawal of two controversial bills and the return of the prime minister to budget deliberations [1], [2].

The move signals a deepening rift between the government and opposition forces over the management of the Diet. If the standoff continues, it could paralyze legislative functions and further erode public trust in parliamentary procedures.

Leaders from the five parties, including the Centrist Reform Coalition, met with Speaker Mori in his office [1]. They requested the immediate withdrawal of the bill to reduce the number of parliamentary seats and the "secondary-capital" bill [2]. The opposition groups also called for a concentrated budget committee session that requires the attendance of Prime Minister Sanae Takayoshi [1].

Opposition representatives described the current state of the legislature as a crisis. Shigenori, the diet affairs committee chair for the Centrist Reform Coalition, said the situation is the worst crisis for parliamentary democracy since the postwar era [1]. He said the government and ruling coalition have continued to refuse deliberations since the initial budget was presented [1].

In a joint statement, the committee chairs of the five opposition parties said the Diet has become abnormal due to unilateral and authoritarian management [2]. They said that this environment is shaking the very foundation of parliamentary democracy [2].

The opposition parties are pushing for a normalization of diet operations to ensure that legislative debates are not bypassed by the ruling majority. They argue that the current approach by the Takayoshi administration ignores the essential role of opposition scrutiny in a democratic system [1], [2].

“the worst crisis for parliamentary democracy since the postwar era”

This escalation reflects a systemic conflict over the balance of power in the Japanese Diet. By framing the government's legislative tactics as a threat to postwar democracy, the opposition is attempting to move the debate from specific policy disagreements to a broader critique of Prime Minister Takayoshi's governance style. The demand for a concentrated budget session is a strategic effort to force the prime minister into a high-visibility public forum where the administration must defend its agenda under direct questioning.
