How to buy American products in Japan
Missing Home?
Welcome to our quick shopping guide for buying American products in Japan.
If you’ve moved here for work or study, chances are you’ve already felt it — that moment when you realize you can’t find your favorite American snacks, creamy peanut butter, or the body wash, shampoo, deodorant, and supplements you use every day.
Japanese supermarkets are fantastic, but the exact U.S. brands we grew up with are surprisingly hard to find.
In this guide, we’ll show you the easiest and safest ways to get American products in Japan — especially on Rakuten Japan, one of the country’s largest marketplaces.
