Japan: girth as well as weight, and a small tier that ends at 250 g
Amazon Japan bands parcels by girth as well as weight, so on its own card a bulky item and a dense one of the same weight do not pay the same fee: inside the 2 kg band the published figures run from 318 to 430 yen depending on dimensions. The schedule here keeps only the weight bands and takes the top of each dimension range, so a compact parcel may be billed less than it shows here. Treat the fulfilment figure as a ceiling rather than a quote.
The small size tier stops at 250 g, the smallest ceiling of any store in this calculator, against 500 g in Canada, Australia and India and 3,900 g in Britain and the euro stores. An item that is comfortably small standard in London is a standard parcel in Tokyo. Above that ceiling the card is short and steep: ¥288 to 250 g, then ¥318 to 1 kg, ¥430 to 2 kg, ¥472 to 5 kg and ¥532 to 9 kg.
Referral rates band by price, not just by category
Japanese referral rates are quoted tax-inclusive and band by price. Most categories charge 5% on the portion of the referral base up to ¥750 and the headline rate only above it, which is why a cheap Japanese listing pays far less than the 15.4% headline suggests. Clothing is banded four ways rather than two: 5%, then 8.4%, then 12.4% between ¥2,500 and ¥3,000, then back to 8.4% above ¥3,000. Only one other row in any of these schedules rises and then falls again, Indian beauty at 0%, 14% and 10%, and no other store does it in four steps.
The per-item minimum is ¥30, and books, music, video and DVD are exempt from it at a flat 15.4%. Jewellery, watches, sports and automotive do not appear in the Japanese schedule at all, so those listings need their rate checked directly in Seller Central.
Prices include 10% consumption tax, stripped from the referral base for a registered seller.
Figures come from Amazon Japan's published pricing pages and its 2026 FBA fulfilment fee revision, effective 1 April 2026.
