Overview

or.jp is a second-level domain under Japan's country code top-level domain (.jp), reserved exclusively for non-profit and organizational entities. It is managed by Japan Registry Services Co., Ltd. (JPRS), the authoritative registry for all .jp domains.

Eligible Registrants

Registration is restricted to Japanese non-profit organizations, including:

  • Foundations (่ฒกๅ›ฃๆณ•ไบบ) and associations (็คพๅ›ฃๆณ•ไบบ)
  • Medical corporations, audit firms, and religious organizations
  • NPOs (็‰นๅฎš้žๅ–ถๅˆฉๆดปๅ‹•ๆณ•ไบบ) and special corporations
  • Agricultural and consumer cooperatives
  • International organizations and their Japanese branches
  • Foreign government embassies and consulates in Japan

Generally, each organization may register only one or.jp domain.

DNS Infrastructure

The or.jp zone is served by Japan's robust DNS infrastructure:

  • Nameservers: a.dns.jp through h.dns.jp (8 anycast servers)
  • Primary SOA: z.dns.jp
  • DNSSEC: Fully signed with validated chain of trust from root
  • Registry: JPRS (Japan Registry Services)

The domain hosts hundreds of subdomains for Japanese nonprofits, NGOs, professional associations, and public-interest organizations.
