Japan is the third-largest ecommerce market in the world, with over $150 billion in annual online spending and 90 million active shoppers (Statista, 2025). For Shopify merchants wondering how to sell on Shopify in Japan, the opportunity is massive but comes with a distinct set of requirements. Japanese consumers have exceptionally high standards for product quality, translation accuracy, delivery speed, and legal transparency. This guide breaks down what you need to know before entering this market.
Japan’s Ecommerce Market: Scale and Expectations
Japan’s ecommerce market is growing at approximately 9% year over year, driven by high smartphone penetration and a mature digital infrastructure. Electronics, fashion, and health and beauty products lead the top categories, with Amazon Japan and Rakuten dominating the marketplace landscape (ecommerceDB, 2025).
What makes Japan unique is the level of detail shoppers expect. Product pages on Japanese ecommerce sites are famously thorough - long-form descriptions, detailed specification tables, multiple product images from every angle, size charts with precise measurements, and extensive FAQ sections are standard. A sparse product page that works in Western markets will feel incomplete to Japanese buyers.
Japanese consumers also place extraordinary trust in brands that invest in proper localization. A store that reads naturally in Japanese signals commitment to the market. A store with awkward machine translation, missing honorifics, or inconsistent terminology signals the opposite. In Japan, the quality of your translation is a direct proxy for the quality of your products.
Legal Requirements: The Specified Commercial Transactions Act
The most important legal requirement for selling online in Japan is the Tokutei Sho Torihiki Ho - the Specified Commercial Transactions Act (SCTA). This law requires every online seller targeting Japanese consumers to prominently display specific business information on their website.
Required disclosures include:
- Seller’s legal name and representative - Your business entity name and the name of the person responsible
- Address and contact information - A physical address and phone number (not just email)
- Product pricing - Including consumption tax (JCT, currently 10%)
- Payment methods accepted - All options must be listed clearly
- Delivery timeline - Expected shipping and arrival dates
- Return and refund policy - Conditions under which returns are accepted
- Additional fees - Shipping costs, handling charges, or any other costs
This information must be easily accessible, typically on a dedicated disclosure page linked from your footer. While the law does not technically require the page to be in Japanese, targeting Japanese consumers with an English-only disclosure page would undermine both compliance intent and customer trust.
Consumption Tax (JCT) Display
Japan’s consumption tax (currently 10%) must be included in displayed prices. Since April 2021, the total amount including tax must be shown to consumers - displaying pre-tax prices alone is not sufficient. Your Shopify store’s pricing for the Japanese market needs to reflect this.
Act on Protection of Personal Information (APPI)
Japan’s data privacy law, the APPI, requires businesses handling personal data of Japanese residents to follow specific collection, storage, and transfer rules. You need a privacy policy explaining how customer data is used, and cross-border data transfers require either consent or adequate safeguards.
Payment Methods: Beyond Credit Cards
While credit cards are the most common online payment method in Japan, limiting your checkout to cards alone means missing a significant portion of the market.
- Credit cards - Visa, Mastercard, and JCB (Japan’s domestic card network) are all widely used. JCB support is particularly important since many Japanese consumers carry JCB cards.
- Konbini payments - Customers receive a payment code and pay in cash at a convenience store (7-Eleven, Lawson, FamilyMart). This is popular with younger shoppers and those who prefer not to enter card details online.
- PayPay - Japan’s largest mobile payment platform with over 60 million users. It has become a mainstream checkout option for online purchases.
- Rakuten Pay - Leverages the massive Rakuten ecosystem. Shoppers can use Rakuten points for purchases.
- Bank transfers (furikomi) - Still used for higher-value purchases, though declining in favor of digital methods.
Shopify supports Japanese payment methods through various payment gateway integrations. Verify your configuration covers at least credit cards (including JCB), konbini, and one or more mobile payment options.
Shipping: Next-Day Is the Baseline
Japanese logistics infrastructure is among the best in the world, and consumer expectations reflect that. Yamato Transport (Kuroneko) and Sagawa Express handle the majority of ecommerce deliveries and offer features that shoppers consider standard, not premium.
Expected shipping standards in Japan:
- Next-day delivery for domestic orders placed before a cutoff time
- Precise delivery time windows - often 2-hour slots that customers select at checkout
- Redelivery scheduling - if a delivery is missed, easy online rescheduling is expected
- Gift wrapping options - particularly around holidays and gift-giving seasons
- Free shipping thresholds that vary but commonly sit around 3,000-5,000 JPY
If you are shipping from outside Japan, you will not match domestic delivery speeds. The key is transparency: clearly state estimated delivery times on your product pages and at checkout, and offer tracked international shipping so customers can monitor their orders. For guidance on configuring Shopify Markets for international shipping, see the Shopify Markets translation guide.
Translation Quality: The Bar Is Higher in Japan
Translating a Shopify store into Japanese is not the same as translating into a European language. Japanese uses three writing systems - hiragana, katakana, and kanji - each with specific use cases. Product names might use katakana for foreign brand terms, kanji for category descriptions, and hiragana for grammatical particles, all in the same sentence.
Beyond script complexity, Japanese business and commerce language requires keigo - honorific language that conveys respect toward the customer. Product descriptions, checkout instructions, customer service emails, and policy pages all need to use appropriate levels of formality. Casual or overly direct language reads as unprofessional or even rude in a commercial context.
This is where generic machine translation often fails. It may produce grammatically correct Japanese that nonetheless sounds unnatural or inappropriately casual. Japanese shoppers will notice immediately.
LocaleFlow handles these nuances automatically. The AI translation engine produces natural Japanese with appropriate keigo formality for commercial contexts. It covers product titles, descriptions, metafields, navigation, checkout flows, and legal disclosure pages - everything a Japanese shopper expects to see in their language. Auto-sync ensures new products and updates are translated without manual intervention. For the full walkthrough on translating to Japanese, see our Japanese translation guide.

Entering a Market That Rewards Excellence
Japan’s ecommerce market rewards merchants who meet its high standards. The legal framework is clear, payment diversity is essential, delivery expectations are demanding, and translation quality is non-negotiable. But at $150 billion in annual revenue with 90 million online shoppers, the prize for getting it right is enormous. Start with a fully translated, legally compliant store, and you build the foundation for long-term success in one of the world’s most valuable ecommerce markets.
