At the establishment of the .jp domain the domain was administered by the JPNIC, as part of their role as an overseeing technical body for the Internet in Japan. However, due to the growing importance and size of the .jp registry, it was decided at the 11th General Meeting of JPNIC in December 2000 to create a new corporation that would manage the .jp domain. Thus, the Japan Registry Service was created, and on June 30, 2003, officially assumed the duties of the .jp registry.
.jp registrations are only allowed if the registrant has a physical address in Japan.
While any party with a Japanese mailing address can get a second-level domain (example.jp) there are several restricted-use second-level domains, listed below.
- ac.jp: higher level academic institutions, such as universities
- ad.jp: JPNIC members

Internationalized country code top-level domain
Japan has considered registering an internationalized country code top-level domain, .日本. As of 2016, no such domain has been registered. But in 2014 an internationalized generic top-level domain using Japanese script was introduced. This is .みんな, meaning "everyone".
