JapanHow long can rescission rights be exercised?
In Japan, rescission rights generally must be exercised within 5 years from the time the right arises, or within 10 years from the time the contract was concluded — whichever comes first.
What the Law Says
Japanese civil law sets strict time limits for exercising rescission rights to ensure legal certainty and protect parties from indefinite uncertainty.
Under the Civil Code of Japan, the general rule is that a party must exercise the right to rescind a contract within 5 years from the time the right arises — for example, from when fraud, mistake, or duress is discovered. However, even if the right has not yet arisen or been discovered, rescission is barred absolutely after 10 years from the date the contract was concluded.
Special rules apply in consumer contexts: the Act on Specified Commercial Transactions provides that consumers may rescind certain contracts (e.g., door-to-door sales, telephone solicitation) within 8 days — or up to 6 months if the seller failed to provide required written notice.
For contracts involving fraud or mistake, Article 126 of the Civil Code allows rescission within 1 year from the time the aggrieved party becomes aware of the fraud or mistake — but again, no later than 10 years from contract formation.
Statutory TextThe right to cancel… shall be extinguished if it is not exercised within five years from the time when the right could have been exercised.
— Civil Code of Japan, Art. 126 — Cancellation due to Fraud or Mistake
Statutory TextIn any case, the right to cancel… shall be extinguished if it is not exercised within ten years from the time when the contract was concluded.
— Civil Code of Japan, Art. 126 — Cancellation due to Fraud or Mistake
Statutory TextA consumer may cancel a contract… within eight days from the day on which the consumer receives the written notice… If the notice is not provided, the cancellation period shall be six months.
— Act on Specified Commercial Transactions, Art. 9 — Door-to-Door Sales
What to Do
Confirm the type of contract and whether consumer protection rules apply.
Identify when the rescission right arose (e.g., date of discovering fraud or mistake).
Calculate both the 5-year (or 1-year) period from discovery and the 10-year absolute deadline from contract formation.
If applicable, check whether the Act on Specified Commercial Transactions extends or shortens the period (e.g., 8 days or 6 months for door-to-door sales).
Send written notice of rescission before the earliest deadline expires.
