①An offerer or purchaser may withdraw an offer to enter into a sales contract or a service contract that falls under the category of any of the following contracts, or may cancel the sales contract or the service contract (hereinafter referred to as "withdrawal of an offer or cancellation" of a contract in this Article); provided, however, that this does not apply if there are special circumstances that make it necessary for the offerer or purchaser to enter into the contract:

②An offerer or purchaser must exercise the right under the provisions of the preceding paragraph within one year from the time of entry into the sales contract or the service contract.

③The provisions of paragraphs (3) through (8) of the preceding Article apply mutatis mutandis to the withdrawal of an offer or cancellation of a contract under the provisions of paragraph (1). In this case, the term "the preceding paragraphs" in paragraph (8) of that Article is deemed to be replaced with "paragraphs (1) and (2) of the following Article and paragraphs (3) through the preceding paragraph as applied mutatis mutandis pursuant to paragraph (3) of that Article".

①If the offerer or purchaser was under a misconception specified in one of the following items as a result of the seller's or the service provider's having engaged in the conduct listed in that item in soliciting the offerer's or purchaser's entry into a sales contract or a service contract connected with a door-to-door sale, because of which the offerer or purchaser indicated the intention to offer to enter or accept a sales contract or a service contract, the offerer or purchaser may retract the manifestation of that intention to offer to enter or accept the contract:

②The retraction under the provisions of the preceding paragraph of the manifestation of the intention to offer to enter into or accept a sales contract or a service contract connected with a door-to-door sale may not be duly asserted against a third party in good faith that is free from any negligence.

③The provisions of paragraph (1) do not preclude the application of the provisions of Article 96 of the Civil Code (Act No. 89 of 1896) to the manifestation of intention to offer to enter into or accept a sales contract or a service contract connected with a door-to-door sale prescribed in the paragraph.

④The right to a retraction under the provisions of paragraph (1) extinguishes by prescription if it is not exercised within one year from the time that a contract can be ratified. The same applies once five years have passed after the time that the relevant sales contract or the service contract was entered into.

⑤Notwithstanding the provisions of Article 121-2, paragraph (1) of the Civil Code, if an offerer or purchaser to whom a benefit has been conferred through the performance of an obligation under a sales contract or a service contract connected with a door-to-door sale retracts the manifestation of the intention to offer to enter into or accept the contract pursuant to the provisions of paragraph (1), but the offerer or purchaser did not know that the manifestation of the intention could be retracted when the benefit was conferred, the offerer or purchaser bears the obligation to return up to the extent of the actual benefit received based on the sales contract or the service contract.

①If a seller or a service provider has entered into a sales contract or a service contract falling under any of the items in Article 5, paragraph (1), but the sales contract or the service contract is canceled, the seller or the service provider may not demand that the purchaser or the service recipient pay an amount of money that exceeds the aggregate of the amount specified in the cases stated in the relevant items among the following items for the cases listed in them and the amount of the relevant damages for delay based on the statutory interest rate, even if there is a provision for liquidated damages or a provision for a penalty:

②If a seller or a service provider has entered into a sales contract or a service contract falling under any of the items in Article 5, paragraph (1), but the obligation to pay the charges under the sales contract or the consideration under the service contract is not performed in whole or in part (excluding cases where the sales contract or the service contract has been canceled), the seller or the service provider may not demand that the purchaser or the service recipient pay an amount of money that exceeds the aggregate of the amount equal to the sales price of the goods or rights or the consideration for the services less the already-paid amount of the charges for the goods or rights or the consideration for the services plus the amount of any damages for delay based on the statutory interest rate, even if there is a provision for liquidated damages or a provision for a penalty.

When a seller or a service provider advertises the terms and conditions under which the seller or the service provider sells goods or specified rights or provides services through mail order sales, the seller or the service provider must indicate the following information concerning the goods, rights, or services in the advertisement pursuant to the provisions of order of the competent ministry; provided, however, that the seller or the service provider is permitted not to indicate a portion of this information, pursuant to the provisions of order of the competent ministry, if the seller or the service provider indicates in the advertisement that upon request the seller or the service provider will deliver a document or provide an electronic or magnetic record that gives this information without delay:

When a seller or a service provider advertises the terms and conditions under which the seller or the service provider sells goods or specified rights or provides services through mail order sales, the seller or the service provider must not make a representation regarding the performance of the goods or the details of the rights or services, regarding information on the withdrawal of an offer to enter into a sales contract for the goods or the rights or a service contract for the service or the cancellation (if there are special provisions as prescribed in the proviso to Article 15-3, paragraph (1), this information includes the details of those special provisions), or regarding any other information specified by order of the competent ministry with respect to mail order sales, that differs significantly from the truth or could mislead people into believing that conditions are significantly better or more advantageous than they are in reality.

On finding that it is necessary to do so in order to determine whether a seller's or service provider's representation falls under the category of representations provided in the preceding Article, the competent minister may ask the seller or the service provider that made that representation to submit materials showing reasonable grounds to support it within a specified period. In this case, if the seller or the service provider fails to submit those materials, with regard to the application of the provisions of Article 14, paragraph (1) and Article 15, paragraph (1), the representation is deemed to fall under the category of representations provided in the preceding Article.
