.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 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.[2]

In April 1989, the junet-admin group began formally registering .jp domain names.[3] 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. Registrations are processed via accredited registrars and domain names with Japanese characters (kanji, hiragana or katakana) may be registered at the second level.

Second-level domains

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.[4]

  • ac.jp: higher level academic institutions, such as universities
  • ad.jp: JPNIC members
  • co.jp: most forms of incorporated companies, including foreign companies registered in Japan
  • ed.jp: educational institutions for individuals under 18
  • go.jp: Japanese government ministries and their endeavours
  • gr.jp: groups of two or more people, or groups of registered companies
  • lg.jp: local government authorities

Internationalized top-level domains

Japan has considered registering an internationalized country code top-level domain, .日本.[6] In 2008, a preliminary application was made.[7] As of 2022, no such domain has been registered.[8]

Private companies have registered the following internationalized generic top-level domains using Japanese script:

  • minna (.みんな, everyone)
  • sēru (.セール, sale)
  • fasshon (.ファッション, fashion)
  • sutoa (.ストア, store)
  • pointo (.ポイント, point)
  • kuraudo (.クラウド, cloud)
  • komu (.コム, com), the most used Japanese script top-level domain
