Japanese citizensf right of petition is guaranteed by the Japanese Constitution.
A petition must be presented in writing to the presiding officer of either House through the introduction of a Member of that House, and then it is considered by a Committee.
If its contents are deemed appropriate, it is adopted in a Plenary Sitting. If it is considered appropriate for the Cabinet to take measures relating to any petition among those adopted, it is then sent to the Cabinet. The Cabinet has to report every year to the House which sent the Cabinet that petition how it handled it.
