'''.jp''' is the [[Internet]] [[country code]] [[top-level domain]] ([[ccTLD]]) for [[Japan]]. It was established in 1986 and is administered by the [[Japan Registry Services]].

==History==
At the establishment of the .jp domain, the domain was administered by the [[Japan Network Information Center|JPNIC]], as part of their role as an overseeing technical body for the Internet in Japan. It was originally proposed by [[Jun Murai]] for the [[Information Sciences Institute]] at the [[University of Southern California]] on August 5, 1986. Handling of the domain was first managed within the "junet-admin" admin group, which was responsible for the operations of [[JUNET]], an early computer network in which Murai was a part of.<ref>{{cite web |title=IANA Report on Request for Redelegation of the .jp Top-Level Domain |url=https://www.iana.org/reports/2002/jp-report-08feb02.html |website=IANA |access-date=October 21, 2020}}</ref>

In April 1989, the junet-admin group began formally registering .jp domain names.<ref name="jp1">{{cite web|title=A New Phase for JP Domain Name Registration and Administration|url=https://www.nic.ad.jp/en/pressrelease/2002/20020228-01.html|access-date=September 18, 2020|quote=Since their introduction in 1989, JP domain names have been registered and managed under such rules as "one domain name per organization" and "prohibition of domain name transfer."}}</ref> 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 [[Domain name registry|registry]].

.jp registrations are only allowed if the registrant has a physical address in Japan. Registrations are processed via [[accredited registrars]] and [[domain name]]s with Japanese characters ([[kanji]], [[hiragana]] or [[katakana]]) may be registered at the second level.
