New to buying from Japan?
Most Japanese online stores ship only within Japan. Two reliable workarounds:
Option A — A proxy buys it for you (easiest)
- Sign up free with Japan Rabbit, Buyee or ZenMarket.
- Paste the store link — they purchase the item for you (no Japanese account or card needed).
- They receive it in Japan and ship it to your country.
Option B — Get your own Japanese address
- Register with a forwarding service like tenso.com or Blackship — you get a personal Japanese address (ID verification required).
- Order on the Japanese store yourself, entering that address as the delivery address.
- When the parcel reaches their warehouse, pay international shipping and they forward it to you.
Heads-up: some Japanese stores decline non-Japanese credit cards — if payment fails, Option A avoids the problem. Always follow each shop's purchase limits and terms.
