Amazon.co.jp is the second-largest Amazon marketplace globally, with over 2.5 billion annual visits and ¥2.5 trillion in annual GMV. It is also one of the most detail-oriented marketplaces — Japanese buyers read the listing thoroughly, check specifications precisely, and rely on the bullet points to make purchase decisions. Conversion on Amazon.co.jp is lower than on Amazon.com, but customer lifetime value is higher when you win trust.
Japanese search behavior is structurally different. Japanese search terms use kanji compounds (スマホケース for phone case, 防水 for waterproof), and buyers often search by use case (一人暮らし for single-person household, プレゼント for present) rather than just by product category. AMZ Lingo generates both category keywords and use-case keywords, so the listing ranks for both buyer intents.
Compliance marks are heavily weighted. PSE (electrical safety) is required for any product with a plug. TELEC is required for wireless products (Bluetooth, Wi-Fi, RFID). 食品衛生法 (Food Sanitation Law) applies to food-contact products. AMZ Lingo detects the relevant compliance category and weaves the right language into the bullet points — not as a footnote, but as a primary trust signal.
Gift-readiness is a unique Japanese pattern. Over 70% of Amazon.co.jp purchases involve gift packaging, gift wrapping, or message cards. Listings that explicitly support 'ギフト対応' (gift-ready) rank higher in gift-related searches and convert at higher rates. AMZ Lingo adds this language where the product is actually giftable, with a flag to confirm packaging before publishing.
Japanese bullet point logic is more formal and information-dense than English. Bullets lead with specifications (耐熱 230°C), include compliance marks (PSE 認証取得), and end with use case (ギフト包装可能). AMZ Lingo applies this pattern automatically for every category, with the right level of formality (敬語 for product claims, polite for descriptions).
Finally, dimensions and units. Amazon.co.jp buyers expect cm/mm for size, g/kg for weight, and °C for temperature. AMZ Lingo converts units from your source listing and outputs in the format Japanese buyers expect. The description is structured to be skimmable, with the key spec at the top of each paragraph.
A successful Amazon.co.jp listing is not a translation — it is a restructure around the Japanese buyer's search, decision, and gift logic. AMZ Lingo is built to produce that restructure in 60 seconds, with the same input as a US listing.
