Is it worth buying in Japan?
The gray 3-pack has the same barcode in both Taiwan and Japan; it's ¥299 per pack in Japan and NT$129 in Taiwan. It's fine to pick up while you're already there; for a small-ticket item, paying extra shipping can easily wipe out the price gap, so it's not worth a special trip just for a pack of sponges.
- With a 1.5% foreign card fee: Japan comes to about US$1.99, still below the US by US$2.91.
- Break-even rate 0.0164 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
- Fixed at the gray 3-pack, JAN 4550512975038; do not compare against the white version or the bath sponge.
- The Japan page has a separate discount for a 5-pack bundle; this entry uses the single-pack price of ¥299.
- The Taiwan price of NT$129 is for a 3-pack; neither side adds separate shipping.
- The Taiwan page showed "add to cart" and "buy now" at the time of verification; stock can still change.
