Is it worth buying in Japan?
This comparison is fixed to a single 300mL bottle, cross-checking the JAN on both the Japan and US official pages. The Japan listed price is ¥1,590 incl. tax and the US price is $19.90; this doesn't apply Japan's 4-bottle bundle or US multi-buy promotions. Shipping and luggage space for bottled skincare should also be factored into your purchase planning. (The Taiwan price is from the PChome 24h retail channel, not MUJI's official Taiwan pricing.)
- With a 1.5% foreign card fee: Japan comes to about US$10.59, still below the US by US$9.31.
- Break-even rate 0.0125 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

- The Japan source's list price is tax-inclusive; the US source does not state its tax basis.
- Both pages showed "add to cart" available at the time of verification; check shipping cost and live stock separately.
