Overview

Identifies Japanese Pokémon cards on Mercari, Buyee and other Japanese sites, and adds up the full cost to your door.

Yenlens is for people buying Japanese Pokémon cards from Japan. Open a card listing on a Japanese marketplace such as Mercari and a small panel shows two things: which card it is, and what it will cost to get it to your door. Which card it is: Japanese listings rarely say exactly which printing a card is. Yenlens reads the title and the seller's description, picks out the set, card number and rarity, and checks them against 13,451 Japanese cards. When it isn't sure, it says so and lets you pick the right one. What it really costs: The listing price is only the start. Yenlens adds up, line by line: - your proxy service's fees - shipping inside Japan, when the seller doesn't cover it - international shipping by post or courier (an estimate) - import charges where you live: VAT, customs duty and the carrier's handling fee in the UK and 13 EU countries, or duty in the US - your card's currency conversion, at today's exchange rate You can change your country, shipping method and currency right on the panel. It also links to recent sold prices so you can check what the card goes for, and warns you when a listing looks like a fake, a non-Japanese card or an auction. What it doesn't do It doesn't buy or bid for you and doesn't need an account. It only reads the listing page you have open. Figures are estimates from published fee and tax rules; your proxy's quote is the final word on shipping.
