Is it worth buying in Japan?
This entry's ranking comes from MUJI Taiwan's own bestseller list; the Japan price is the same-day tax-included listed price for the same barcode item on Japan's official online store. Japan shipping, tax refunds, and card fees are not included, and the Taiwan page does not state its tax basis.
- With a 1.5% foreign card fee: Japan comes to about US$0.80, still below the US by US$1.60.
- Break-even rate 0.0200 USD/JPY: above it the the US sticker is the cheaper one (this check used 0.0066, cross-converted from the Bank of Taiwan yen and dollar rates).
Before you buy
- Confirm the barcode 4550344872703 matches on both sides, and the spec (Japan: 0.3mm, black).
- The Taiwan price is MUJI Taiwan's official online store list price; the page does not state whether tax is included.
- Being listed on the official online store does not mean it is in stock at a given physical store; check availability again before buying.
