Description
You don’t have to live in Japan to have the full hanko experience! Through the World Hanko Registration Center (WHRC), you can register your Hanko that you acquired from Hanko Square. Our process is similar to the multi-factor authentication local Japanese governments use to register and verify name stamps (called “Jitsu-in”) for the most important official documents and large transactions an individual can sign. Learn more about Jitsu-in here.
Protecting and Authenticating your stamp is as easy as 1, 2, 3!
- Register your Hanko with the World Hanko Registration Center
- Request Verification Certificates (purchased separately)
- Receive Certificates on special copy-proof paper

Disclaimers:
The World Hanko Registration Center is a private entity, and is not a governmental agency. We do not claim the same level of authority as a municipal office. Registering with us does not confer the official status of jitsu-in to your hanko in Japan; you will still need to register with your local municipality if you need a jitsu-in.
The maximum liability of any claim against the veracity of a WHRC certificate is the value of the registration itself: 3,000 Japanese yen.
To avoid abuse of the Hanko Registration System, we are only able to register hanko purchased directly from Hanko Square online, or Hankoya21 stores in Japan. Only the original owner may register their hanko.
If you wish to transfer ownership of your registered hanko such as to pass on an heirloom or to choose a successor for your martial arts dojo or organization, please use the contact form on this page to get in touch.
