Selling on Amazon Japan: FBA Entry Guide for Taiwan Brands

Japan is the third-largest e-commerce market globally, and Amazon Japan accounts for approximately 20% of Japanese online retail. The market is underserved by global brands compared to the US — Japanese consumers are premium buyers who pay for quality, precision, and reliability.

Taiwan has strong cultural and geographic proximity to Japan. Taiwanese manufacturers already supply many Japanese OEM brands. Entering Japan under your own brand captures margin that currently goes to Japanese trading companies acting as intermediaries.

The challenge: Japan has strict product safety standards, Japanese-language listing requirements, and buyer expectations around packaging and communication quality that differ from Western markets. Shortcuts that work on US Amazon often fail on Amazon Japan.

You can open an Amazon Japan seller account through Amazon Global Selling. Go to sell.amazon.co.jp and register. You can link your existing US Seller Central account — Amazon's unified account system allows one seller account to manage multiple marketplaces.

Required documents: business registration certificate, identity verification (passport for individual or representative), bank account for JPY payouts (a Japanese bank account is ideal but not required — Amazon's Hyperwallet service can route payouts to Taiwan or international accounts), and tax information.

Monthly fee: ¥4,900/month (approximately $33) for a Professional seller account. Amazon Japan charges a referral fee of 8–15% depending on category, similar to US rates.

Fulfillment options: FBA Japan (ship inventory to Amazon's Japanese fulfillment centers in Narita, Osaka, etc.), or Amazon Global Logistics which offers a streamlined Taiwan-to-Japan FBA pipeline.

PSE (Product Safety of Electrical Appliances and Materials Act): required for electrical products sold in Japan. Two tiers: Diamond PSE mark (high-risk appliances like irons, air conditioners — requires third-party certification) and Circle PSE mark (lower-risk appliances like chargers, batteries — self-certification against technical standards with required testing).

PSC (Consumer Product Safety Act): covers specific non-electrical products with injury risk. Products in PSC categories (pressure cookers, helmets, etc.) require inspection and a PSC mark.

Food products: require Japanese Food Sanitation Act compliance — ingredient labeling in Japanese, additive regulations, and potential import notification to Japan's Ministry of Health.

Many Taiwan manufacturers already hold PSE/PSC for their OEM clients. If your factory's product is already PSE-certified for a Japanese buyer, verify whether that certification can be transferred to your brand or whether new certification is required (it usually requires new paperwork but not new testing if the product is identical).

Amazon Japan listings must be in Japanese. Machine translation (Google Translate, DeepL) produces technically correct but unnatural Japanese that Japanese consumers immediately recognize as foreign-origin copy — this reduces conversion rates significantly.

Hire a native Japanese copywriter with e-commerce experience for your top ASINs. Key elements requiring professional translation: product title (keep under 60 characters), bullet points (5 points, each under 100 characters), product description, and A+ Content.

Japanese buyers read all the bullet points before purchasing. They expect specificity: exact dimensions in millimeters (not centimeters), specific material grades, country of origin, and compatibility specifications. Vague descriptors common in US listings ("premium quality," "durable material") are less persuasive to Japanese buyers than precise technical specifications.

Main image standards are identical to Amazon US (white background, product fills 85% of frame). Additional images should include size comparison shots with common reference objects (a hand, a 500ml water bottle) — Japanese buyers consistently respond to scale context.

Packaging quality matters enormously in Japan. Even if the inner product is identical, Japanese buyers expect outer packaging to be pristine — no printing misalignments, no scratches, proper Japanese-language labeling. Products that arrive with visibly factory-sealed but imperfect packaging generate disproportionate negative reviews in Japan.

Customer service expectations: Japanese buyers expect fast, polite, detailed responses. Response time of over 24 hours is considered slow. Use a Japanese-speaking virtual assistant or CS service for Japan marketplace messages — automated English responses are not acceptable.

Returns: Japan has a 30-day return window on Amazon. Japanese return rates are typically lower than US rates (Japanese buyers research more before purchasing), but returns that do happen are often due to packaging damage or spec mismatches — both preventable with careful quality control.

Pricing: Japan is a premium market. Do not underprice relative to your Japanese competitors. Japanese buyers associate low price with low quality. If your product is priced below established Japanese brands, test raising the price — conversion rates sometimes improve.
