What's inside
🛍️ Shop
How Japanese retail works, a field guide to 12 store types (department stores, depachika food basements, 100-yen shops, drugstores and more), paying at the register, tax-free basics, fitting-room etiquette, store manners, sale seasons and getting it all home — 97 entries in plain English.
📏 Size Decoder
Tap your US, UK or EU size and get the Japanese size to look for — women's and men's clothing and shoes, with the size-culture basics explained. Approximate by design; the fitting room decides.
🏷️ Price Tag Decoder
The kanji on Japanese price tags, made tappable: tax-included and before-tax prices, the fraction-off discount system, half-price stickers, flat-price signs and per-customer limits.
🎁 Souvenir Decoder
36 gifts that actually land — with how to pick a good one, filterable by food, crafts, cute, practical or bulk-friendly. Plus the unwritten rules of omiyage culture.
💬 Phrases
30 sentences for asking, trying on, paying, tax-free and gift wrapping — each with a full-screen version you can simply show at the counter.
