Click on the subject below to open the dropdown for more information.

Successful domain registration via RCP or API requires:

  • The domain's contact handles (owner, administrative, etc.)
  • Local presence required - local presence service available (not for .co.jp requests)
  • Two or more nameservers or a nameserver group
  • First and last name required

This registration is real time
If you provide a Japanese address for one of the contacts, the "state/province" field is mandatory and must contain the 2-digit prefecture code.
A list of prefecture codes is available here; be sure not to include the "JP-" prefix, just the number.

co.jp: In case of a co.jp, additional documents are required (business license or ID card + registration form). You will receive an email with instructions after the registration.

Successful domain transfer via RCP or API requires:

  • authorisation code
  • the domain's contact handles (owner, administrative, etc.)
  • Local presence required - local presence service available (not for .co.jp requests)
  • two or more nameservers or a nameserver group
  • The current owner contact information is required, a change of registrant is NOT possible during the transfer

Authorisation code for .jp is also called "REG-ID" and can be provided by the current registrar

If the current registrar can't provide you a valid REG-ID, please send us an email to support@openprovider.com informing us about it, we will request a transfer without code. After requesting the transfer the owner will receive an email requesting transfer approval. After approval is given the transfer takes a few more days to complete.

Additional notes on a .jp transfer

Transfers are NOT possible, if the domain is expiring within the next 30 days.

Authorization code required yes
Method of confirmation authcode,email
Registration period after transfer unchanged
Average transfer time Max 7 days
Advanced and simple transfers available Contact our Sales department to check if easy transfer of 100 or more .jp domains is available.

Once a transfer has been initiated from the gaining registrar, please contact Openprovider Support
to approve the transfer manually.

If the owner contact does not have a Japanese address, you need to set a new owner contact with a Japanese address or otherwise it is not possible to transfer away. This is required due to the usage of a proxy address for non Japanese registrants, which has to be updated with an own one prior to the transfer out.
