How to buy Amazon JP Books

Amazon JP account

To buy books on the Japanese Amazon site, you will an Amazon account on that is separate from your local one. It is recommended to use a different email address to register for the Japanese account.

You can switch to the English interface if you are not used to the Japanese one.

The display language does not affect the book selection or recommendations on the site.


Check the address bar to make sure the web address still uses the domain in case you have been redirected to the global site.

Japanese address

A Japanese address is required for account registration.

You will get an error if you fill in random numbers since it checks against real Japanese post codes.

You can use services like DANKEBOX to get a free Japanese address and P.O. box.


The P.O. box can also come in handy if you plan on buying physical goods on Amazon or other websites like Rakuten and Mercari.

You will have to pay for the shipping cost for DANKEBOX to mail you the items, but it's still great to have access to a much larger Japanese market of new and second-hand items that do not offer worldwide shipping.

Other similar services: Tenso, White Rabbit Express

Japanese VPN

A Japanese VPN is usually not required for shopping on, but some people have experienced regional issues.

If you see the following message, simply changing your account's region will not resolve the problem.


In this case, consider purchasing a VPN service or hosting your own VPS using tools like Outline VPN.
