The main sale has ended (it ran from Fri, Oct 16, 2026, 0:00 to Mon, Oct 19, 23:59 JST). Prices and discount rates are taken from each product's Amazon.co.jp page.

How the Sale Works, and Tips to Use It Well

The Prime Appreciation Sale included a "points bonus campaign." After signing up during the entry period (Sept 24, 14:00 JST to Oct 19, 23:59 JST) on Amazon's official site, spending 10,000 yen (tax included) or more during the purchase period (Oct 13, 0:00 JST to Oct 19, 23:59 JST) earned bonus points, up to 10,000 time-limited points depending on how much you spend. Some products, including Apple products, are excluded. Check Amazon's official page for the full conditions.

During the main sale (Oct 16-19), there was a "daily featured deal" (厳選日替わりセール) where the discounted products changed each day. Amazon's official page notes that the comparison price is based on the same product's Amazon.co.jp price since January 1, 2026, not a promise about future prices. For anything you're considering, it's worth checking the product page itself before buying to see whether the deal is actually worth it.

Daily goods are things you use at a fairly steady pace, so it's worth thinking about storage space and how fast you'll actually use something up before buying more than you need just because it's on sale.

If you're not a Prime member yet, a 30-day free trial lets you try Prime perks too.

Checks Before You Buy in a Sale

Basic checks that apply to any product you buy in a sale.

  1. Check the brand, size and count match. Compare the brand, pack size and count on the product page with what this article lists. Refill packs, starter sets and different sizes often sit side by side.
  2. Compare the price on both Amazon and Rakuten Ichiba. Along with the listed price, look at shipping and points, which also change what you actually pay.
  3. Check expiry dates where they apply. For things like bottled water, check the product page or reviews for freshness information.
  4. See who is selling it. On Amazon check the seller and shipper; on Rakuten Ichiba check the shop name.
  5. Think about storage space and how fast you'll use it. A bulk pack can be cheaper per unit, but only order what you have room for and will actually use.

How We Chose These Products, and Sources

Selection basis
We chose from daily goods that were genuinely discounted on Amazon.co.jp at the time (a real price cut from the usual price), focusing on bulk packs and large multi-packs.
Amazon and Rakuten check
For each product we looked at the product pages on Amazon and Rakuten Ichiba and listed it only if the brand, size and count match. Products we could confirm on only one of the two are not listed.
Sources of specs and photos
Key specs come from the pages listed under each product's sources (manufacturer's official site, Rakuten Ichiba product pages and so on). Photos are product images from Amazon.co.jp.
Prices
Prices, reference prices and discount rates are taken from each product's Amazon.co.jp page (with the delivery address set to Japan). Prices change often, so please check the current price on each product's Amazon page.
About medicines
Over-the-counter medicines are not covered in this article.
About protein (a dietary supplement)
Protein powder is a dietary supplement, not a medicine. We describe only facts -- brand, flavor, volume -- and make no efficacy or health-effect claims.
