Japan Specified Commercial Transactions Act Compliance Guide for Taiwan Ecommerce Sellers

The Act on Specified Commercial Transactions (Tokutei Shoutorihiki-hou), originally enacted in 1976 and substantially amended multiple times including significant updates in 2021 and 2022, is Japan's primary consumer protection law governing ecommerce transactions, mail-order sales, door-to-door sales, and telemarketing. For Taiwan ecommerce sellers targeting the Japanese market through platforms like Amazon Japan, Rakuten, Yahoo Shopping Japan, or independent Shopify stores, this law imposes mandatory requirements on business disclosures, transaction terms, advertising content, and return policies. The law is enforced by the Consumer Affairs Agency (CAA, Shouhisha-chou) and violations can result in administrative orders, business suspension, fines up to JPY 3 million (approximately USD 20,000), and imprisonment up to 2 years.

The Act categorizes commercial transactions into seven types: door-to-door sales, mail-order sales (tsushin hanbai), telemarketing sales, chain marketing transactions (multi-level marketing), specified continuous service offers, business opportunity sales, and visit purchases. Taiwan ecommerce sellers primarily fall under the mail-order sales category, which encompasses all transactions where the consumer places an order through the internet, catalog, television, or other remote means. The mail-order sales provisions require specific disclosures before the consumer makes a purchase and impose restrictions on advertising claims and business practices.

Foreign sellers are not exempt from the Specified Commercial Transactions Act when selling to Japanese consumers. The CAA has explicitly stated that the Act applies to any seller, regardless of location, that directs commercial activities toward Japanese consumers through Japanese-language websites, Japanese marketplace platforms, or marketing specifically targeting Japan. Taiwan sellers listing products on Amazon Japan or advertising through Japanese social media channels are subject to the full scope of the Act's requirements. Ignorance of the law or being based outside Japan is not a valid defense against enforcement actions.

The 2021 amendments to the Act introduced new provisions specifically addressing digital commerce, including requirements for final order confirmation screens that clearly display the total price, quantity, payment timing, and cancellation conditions before the consumer clicks the purchase button. These amendments were prompted by increasing complaints about subscription traps and hidden charges in online shopping. Taiwan sellers must ensure their checkout flows, whether on marketplace platforms or independent stores, comply with these enhanced disclosure requirements. Amazon Japan and Rakuten automatically handle some of these disclosures through their platform checkout systems, but sellers with independent stores must implement compliant checkout flows themselves.

The Specified Commercial Transactions Act requires mail-order sellers to display specific business information prominently on their website or marketplace storefront. The required disclosures include the seller's legal name (corporate name for companies or full name for sole proprietors), physical address, telephone number, name of the person responsible for the business, product prices including tax, shipping fees and any other charges, payment methods accepted, delivery timeframes, and return and cancellation policies. For foreign sellers including Taiwan companies, the address must include the overseas address of the seller's principal business location. If the seller has appointed a representative in Japan, that representative's name and address must also be disclosed.

The disclosure must be displayed in a location that is easily accessible to the consumer before they make a purchase decision. On marketplace platforms like Amazon Japan, seller information is displayed in the seller profile section, and the platform provides structured fields for entering this information. On independent ecommerce stores, the disclosure is typically placed on a dedicated "Specified Commercial Transactions Act Disclosure" page (Tokutei Shoutorihiki-hou ni Motozuku Hyouji) linked from the website footer. This page must be written in Japanese, and all monetary amounts must be displayed in Japanese yen.

Taiwan sellers must be particularly careful about the return and cancellation policy disclosure. Under the Act, mail-order sellers may establish their own return policy, but this policy must be clearly stated before the purchase. If the seller does not clearly disclose a return policy, the default rule under the Act applies: the consumer has the right to return the product within 8 days of receipt at the seller's expense. This 8-day period functions similarly to a cooling-off period for mail-order transactions, though technically the Act distinguishes between the cooling-off rights (applicable to door-to-door and telemarketing sales) and the mail-order return rights. Many Taiwan sellers are unaware of this default and fail to establish a clear return policy, inadvertently giving consumers broad return rights.

The Act also requires sellers to provide an email address for order confirmations and inquiries. Automated order confirmation emails must include the seller's name, the product ordered, the total price, the payment method, the expected delivery date, and the seller's contact information. For Taiwan sellers using Amazon Japan's FBA service, Amazon handles order confirmation emails, but sellers using Merchant Fulfilled shipping must send their own compliant confirmation emails. LNH31 Global recommends creating a standardized Japanese-language email template that includes all required disclosures and having it reviewed by a Japanese regulatory consultant before deployment.

The cooling-off period under the Specified Commercial Transactions Act varies by transaction type. For door-to-door sales and telemarketing sales, consumers have an unconditional right to cancel within 8 days of receiving the contractual document, even if the product has been delivered and opened. During this cooling-off period, the consumer does not need to provide any reason for cancellation, and the seller must bear all costs of the return including shipping. For mail-order sales, which covers most ecommerce transactions, the Act does not mandate a fixed cooling-off period but establishes the 8-day default return right when the seller has not clearly disclosed a return policy.

Taiwan ecommerce sellers can limit or modify the default 8-day return right by clearly disclosing their return policy before the purchase. For example, a seller may state that returns are accepted only for defective products, or that the consumer must bear return shipping costs. However, these limitations must be conspicuously displayed, written in clear and understandable Japanese, and brought to the consumer's attention before the order is placed. Hiding the return policy in fine print or requiring consumers to click through multiple pages to find it may be deemed insufficient disclosure under CAA enforcement guidelines.

The 2021 amendments added specific requirements for subscription and recurring purchase models that are particularly relevant to Taiwan brands selling consumable products like supplements, beverages, or skincare items. If a product is sold on a subscription or automatic replenishment basis, the seller must clearly disclose the total amount the consumer will pay over the subscription period, the number of deliveries, the cancellation method, and any conditions or penalties for early cancellation. The CAA has issued administrative orders against multiple ecommerce sellers who advertised low "initial purchase" prices for subscription products without clearly disclosing the total commitment, a practice known as "subscription traps" in Japanese consumer protection enforcement.

For Amazon Japan sellers, the platform's default return policy generally allows returns within 30 days of delivery for most product categories, which is more generous than the Act's 8-day default. Amazon's return policy supersedes the seller's own policy for FBA products, as Amazon processes returns directly. However, for Merchant Fulfilled products, the seller's disclosed return policy applies, and sellers must ensure it meets the Act's requirements. Taiwan sellers should familiarize themselves with Amazon Japan's return policy by product category, as some categories (such as food, beverages, and personal care items) have different return rules due to hygiene and safety considerations.

The Specified Commercial Transactions Act prohibits misleading advertising in mail-order sales. Sellers must not make false or exaggerated claims about product quality, performance, price, or terms of sale. The Act works in conjunction with the Act Against Unjustifiable Premiums and Misleading Representations (Keihin Hyouji-hou) to create a comprehensive framework for advertising regulation. Specific prohibitions include bait-and-switch advertising (advertising products at low prices with the intention of selling more expensive alternatives), unauthorized use of endorsements or certifications, and failing to disclose material conditions or limitations associated with advertised offers.

The penalties for violating the Specified Commercial Transactions Act are substantial and escalating. The CAA may first issue an instruction (shiji) ordering the seller to correct the violation, which is an informal administrative action. If the seller fails to comply or if the violation is serious, the CAA can issue an administrative order (gyousei shobun) requiring specific corrective actions within a set timeframe. For the most serious violations, the Act provides for criminal penalties: fines of up to JPY 3 million (approximately USD 20,000) for individuals, up to JPY 3 million for corporations, and imprisonment of up to 2 years for responsible individuals. Administrative orders are published on the CAA's website, creating reputational damage in addition to legal consequences.

The 2022 enforcement trends show increased CAA attention to cross-border ecommerce sellers, particularly those operating through Japanese marketplace platforms. The CAA has collaborated with platform operators including Amazon Japan and Rakuten to identify non-compliant sellers and has issued warnings to foreign sellers through the platforms' seller communication systems. In several cases, platforms have suspended seller accounts at the CAA's request before formal enforcement action was taken. Taiwan sellers should view platform compliance requirements not just as marketplace rules but as extensions of Japanese law enforcement.

LNH31 Global recommends that Taiwan sellers conduct a comprehensive compliance audit of their Japanese ecommerce presence at least annually. This audit should review all product listings for advertising claims, verify that the Specified Commercial Transactions Act disclosure page is current and complete, confirm that the checkout process meets the 2021 amendment requirements for final order confirmation screens, and check that return policy disclosures are conspicuous and compliant. Hiring a Japanese regulatory consultant for an annual compliance review typically costs JPY 100,000 to JPY 300,000 (approximately USD 670 to USD 2,000) and is a worthwhile investment compared to the potential fines and account suspensions resulting from non-compliance.

Taiwan sellers should also be aware of the Act's provisions regarding unsolicited commercial emails. The Act prohibits sending commercial emails to consumers who have not opted in to receive them, and requires all commercial emails to include the sender's identity, contact information, and an unsubscribe mechanism. Violating the email marketing provisions can result in fines of up to JPY 1 million for individuals and up to JPY 30 million for corporations under the 2008 amendments. If your Japanese marketing strategy includes email campaigns, ensure full compliance with both the Specified Commercial Transactions Act and Japan's separate Act on Regulation of Transmission of Specified Electronic Mail.
