第四条（消費者契約の申込み又はその承諾の意思表示の取消し）
A consumer may rescind the manifestation of an intention to be bound by the offer of a consumer contract or by the acceptance of such an offer if either of the acts set forth in the following items taken by the trader in soliciting the consumer to enter into the consumer contract caused the consumer to be under the mistaken belief prescribed in the items, and manifested the intention to be bound by the offer of that consumer contract or by the acceptance of such an offer:
conveying something that diverges from the truth with regard to an important matter:a mistaken belief that what has been conveyed is true;
重要事項について事実と異なることを告げること。 当該告げられた内容が事実であるとの誤認
providing a conclusive assessment of future prices, amount of money that a consumer will receive in the future, or any other matters whose changes in the future is uncertain, in connection with goods, rights, services or other things for the purpose of a consumer contract:a mistaken belief that the content of the conclusive assessment provided is certain.
A consumer may rescind the manifestation of an intention to be bound by the offer of a consumer contract or by the acceptance of such an offer if a trader in soliciting the consumer to enter into the contract, conveys to the consumer that an important matter or matters related to the important matter would be advantageous to the consumer, and also fails to convey a fact regarding that important matter that would be disadvantageous to the consumer intentionally or with gross negligence, (limited to a fact that a consumer would normally think to be non-existent based on what has been conveyed), causing the consumer to mistakenly believe that the fact in question does not exist, and therefore the consumer has manifested the intention to be bound by the offer of the consumer contract or by the acceptance of the offer; provided, however, that this does not apply if the trader has attempted to convey the relevant fact to the consumer and the consumer has rejected the attempt.
A consumer may rescind the manifestation of an intention to be bound by the offer of a consumer contract or by the acceptance of such an offer if the consumer manifested that intention as a result of being overwhelmed by any of the following acts taken by the trader in soliciting the consumer to enter into the consumer contract:
preventing a consumer from leaving the place where the trader is soliciting the consumer to enter into the consumer contract, in spite of the consumer's request to leave.
moving to a place together with the consumer and soliciting to enter into the consumer contract in that place while knowing that it is difficult for the consumer to voluntarily leave that place without informing the consumer that they are soliciting to enter into the consumer contract;
in spite of the consumer expressing an intent to contact a person other than the trader by telephone or other means specified by Cabinet Office Order in order to have a consultation on whether or not to enter into the contract, using intimidating words and deeds and preventing the consumer from making said contact in a place where the consumer is being solicited to enter into the consumer contract;
while knowing that a consumer who has little social life experience is overly worried about fulfilling the aspirations regarding the following matters, the trader prompts fears of the consumers and conveys that the goods, rights, services and any other things for the purpose of the consumer contracts are necessary to fulfill the consumer's aspirations although there are no reasonable grounds or rational basis supporting that necessity, in matters such as:
education, employment, marriage, livelihood and other important matters of social life;
進学、就職、結婚、生計その他の社会生活上の重要な事項
physical appearance, body type and other important matters related to physical characteristics or conditions;
容姿、体型その他の身体の特徴又は状況に関する重要な事項
a consumer who has little social life experience develops romantic feelings or other favorable feelings toward a trader who solicits consumer contracts and knowing that the consumer may mistakenly believe that the trader has romantic or favorable feelings toward the consumer, the trader takes advantage of this situation, conveys to the consumer that the relationship between them will break down unless the consumer enters into the contract;
while knowing that a consumer is overly worried about maintaining their current life with respect to livelihoods, health and other matters because their decision-making capacity is extremely low due to aging or mental and physical disorders, the trader takes advantage of the situation, prompts their fears and although there are no reasonable grounds for supporting solicitation nor any other rational basis, the trader states that it will be difficult for the consumer to maintain their current life unless the consumer enters into the contract;
the trader indicates to the consumer, in order to fuel their fear, that supernatural senses or other special abilities that are difficult to reasonably verify have shown that it would be impossible to avoid a serious disadvantage that could happen in the present or future to the life, person, property, or other important matter of the consumer or a relative of the consumer unless the consumer takes certain measures, or takes advantage of the fact that the consumer holds such fear, and informs the consumer that entering into the consumer contract is indispensable for avoiding those serious disadvantages;
before a consumer makes a manifestation of intention of an offer for a consumer contract or acceptance of such an offer, the trader implements, in whole or in part, the obligations that are supposed to be fulfilled when the consumer enters into the contract, or changes the state of the subject matter of the consumer contract, thus making it extremely difficult to restore the situation to the original status before the implementation or change;
in addition to what is provided for in the preceding item, when the trader performs investigations, provides information, procures goods, or performs other business activities aiming at concluding a consumer contract before the consumer makes a manifestation of intention of an offer for a consumer contract or acceptance of such an offer, tells the consumer that the business activities have been performed in particular for the consumer, and also requests compensation for losses caused by the implementation of those business activities despite the fact that there was no special request from the consumer for those business activities, nor any reasonable grounds in light of other business social norms.
A consumer may rescind the manifestation of an intention to be bound by the offer of a consumer contract or by the acceptance of such an offer if the trader knew in soliciting the consumer to enter into the consumer contract, that the quantity, the frequency, or the duration (hereinafter referred to in this paragraph as a "quantity, frequency, or duration") of the goods, rights, services or other things for the purpose of the consumer contract greatly exceeded the normal quantity, frequency, or duration for a consumer (meaning the quantity, frequency, or duration that would normally be presumed to be that of the purpose of such a consumer contract in light of the transaction conditions and the content of the purpose of the contract, the consumer's situation in life at the time of the trader's solicitation to enter into the contract, and the consumer's awareness of this; hereinafter the same applies in this paragraph), and if the consumer manifested the intention to be bound based on that solicitation. The same applies if a trader knew in soliciting a consumer to enter into a consumer contract, that the consumer had already entered into another consumer contract whose purpose was of the same type as the purpose of the consumer contract the trader was soliciting (hereinafter referred to in this paragraph as the "contract of the same type") and the total quantity, frequency, or duration of the purpose of the contract of the same type and that of the consumer contract in question greatly exceeds the normal quantity, frequency, or duration for a consumer, and the consumer manifested the intention to be bound based on that solicitation.
