Is it worth buying in Japan?
The medium soft storage box converts to approx. NT$122 in Japan versus NT$239 in Taiwan, nearly double, but an empty box takes up luggage space, so bringing back one to use as a packing divider works out fine.
- With a 1.5% foreign card fee: Japan comes to about US$3.93, still below the US by US$4.97.
- Break-even rate 0.0151 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
- Verify both official pages show the same barcode 4547315197842; Japan spec 中 約幅２５．５×奥行３６×高さ１６ｃｍ
- The Japan price is the official product page's tax-inclusive list price as of 2026-09-15 (not sold online — must be purchased in-store); the Taiwan page does not state whether tax is included.
- The ranking comes from a snapshot of Taiwan's official bestseller list; being listed on the official online store does not mean it is in stock at a given physical store.
