What is a .JP domain?

.JP is the country-code top-level domain (ccTLD) for Japan.

It is widely used by businesses, organizations, and individuals connected to Japan, and is a strong choice for establishing a local presence in the Japanese market.

Who can register a .JP domain?

Anyone can register a .JP domain. If the registrant does not have a local Japanese address, a local presence service may be provided automatically to meet registry requirements.

Registration restrictions

While .JP domains are generally accessible, the registry enforces specific contact and formatting requirements:

• A local Japanese address is required
  • If the registrant does not provide one, it may be supplied automatically through a local presence service
• If Japan (.JP) is selected as the country for any contact (Owner, Admin, Tech, or Billing), the following applies:
  • The “State” field becomes mandatory
  • It must include the correct 2-digit prefecture code based on the JIS X 0401 standard (ISO 3166-2:JP)

Domain requirements

.JP domains must follow standard naming rules:

• Domain length must be between 1–63 characters
• Allowed characters: letters (a–z), numbers (0–9), and hyphens
• Hyphens cannot be used at the beginning or end of the domain name
• No spaces or special characters
