JapanRequirements for state redress from facility defects?
In Japan, state redress for facility defects is governed by the State Redress Act, which requires proof that a public facility was defective, that the defect caused harm, and that the state failed to maintain it properly.
What the Law Says
The State Redress Act sets out the conditions under which individuals may seek compensation from the Japanese government for harm caused by defective public facilities.
Under Japanese law, the state is liable for damages arising from defects in public facilities—such as roads, bridges, parks, or government buildings—if the defect resulted from inadequate maintenance or management. This liability arises not from negligence alone but from the state’s duty to ensure public facilities are safe for ordinary use.
The claimant must prove three elements: (1) the existence of a defect in the public facility; (2) causation between the defect and the damage suffered; and (3) that the defect stemmed from the state’s failure to fulfill its duty of proper maintenance or management.
Claims must be filed within two years from the time the injured party becomes aware of both the damage and the identity of the responsible public entity. This deadline is strictly enforced.
Statutory TextThe State shall compensate any person who has suffered damage as a result of the infringement of his rights or interests by an unlawful act of a public official in the course of his duties.
— State Redress Act, s. 1 — General Principle of Liability
Statutory TextWhere damage is caused by a defect in the installation or management of a public facility, the State or a public entity shall compensate any person who has suffered damage thereby.
— State Redress Act, s. 2 — Liability for Defects in Public Facilities
What to Do
Confirm the facility qualifies as a 'public facility' under the State Redress Act (e.g., roads, schools, municipal buildings).
Gather evidence of the defect (photos, inspection reports, witness statements) and its causal link to your injury or loss.
File a written claim with the responsible public entity (e.g., national ministry or local government) within 2 years of discovering the damage and responsible party.
If the claim is denied or unanswered after 60 days, you may file a lawsuit in district court.
