We live in what is sometimes referred to as a contractual society. Without even realising it our lives are bound by a variety of contracts.
A contract is completed not just by the exchange of contract documents, but also by the declaration of application and consent. However, contracts agreed under the following circumstances are considered invalid and will be cancelled.
(1) contracts completed by a minor without the consent of a parent
(2) the details of the contract have been misunderstood
(3) the contractor knew that the contractee did not truly agree
(4) the contract was completed against that contractee’s will, either using threats or fraud
(5) confusion or misunderstanding occurred during the signing process (as defined in the Consumer Contracts Law)
It is easy for contractual problems to arise because foreign nationals may not
always have completely understood the contract. So, if you are planning to enter
into a contractual agreement, it is a good idea to consult a Japanese friend
and proceed with caution (>>Consumer Affairs).
