Step-by-Step Process
Step 1
The House passes a no-confidence resolution
A no-confidence motion against the cabinet requires a simple majority in the House of Representatives. It may be filed by any member and debated on the floor. The vote typically follows a period of intense political pressure on the government.
Step 2
The prime minister faces a binary choice
Under Article 69 of the Constitution, once the motion passes, the cabinet must either resign en masse within 10 days or dissolve the House of Representatives and call a general election. There is no middle ground.
Step 3
Dissolution triggers a snap election
If the prime minister chooses dissolution, a general election for the House of Representatives must be held within 40 days. The existing cabinet continues in a caretaker capacity until the election and the formation of a new government.
Step 4
Strategic context
No-confidence motions are common in Japanese politics but rarely succeed because the ruling LDP coalition has usually maintained a majority. When they do pass, the choice between resignation and dissolution depends on whether the PM believes a new election could return a favourable result.
