Japan was an early participant in the Internet. JUNET (Japanese University Network) was established in 1984 to interconnect Japanese universities, and in 1985, network connectivity tests began. In 1986, JUNET became connected with CSNET and USENET. <a href="/Jun_Murai" title="Jun Murai">Jun Murai</a> was the key person during this process. On 5 August 1986, soon after deployment of the current domain-name system in 1984 and 1985, the .jp <a href="javascript:void(0);" class="mw-lingo-term" data-lingo-term-id="a7bd4b3f417b16c430afe50d4c8ecff3">ccTLD</a> was delegated by <a href="/Jon_Postel" title="Jon Postel">Dr. Jon Postel</a> (then in charge of the <a href="javascript:void(0);" class="mw-lingo-term" data-lingo-term-id="7a11d20162183065066be0792416c70b">IANA</a> function at the Information Sciences Institute) to Jun Murai. </p><p>Jun Murai began at first to manage and administer the .jp <a href="javascript:void(0);" class="mw-lingo-term" data-lingo-term-id="a7bd4b3f417b16c430afe50d4c8ecff3">ccTLD</a> from within the "junet-admin" group, which was responsible for the operation of JUNET. Initially, JUNET had been using the top-level domain name ".junet," but it was suggested by Jun Murai that the Japanese Internet community should instead use .jp, as international rules concerning top-level domains were being established. In April 1989, junet-admin began registration of .jp domain names. Transfer from .junet to .jp was completed in approximately three months, and .junet domain names were replaced with such domains as .ac.jp and .co.jp. </p><p>Considering the accelerating Internet development, it became difficult to quickly respond to the needs of the Internet users in Japan. After extensive discussion among various Japanese academic societies the JCRN (Japan Committee for Research Networks) was established, which made the decision to create JNIC (Japan Network Information Center) in December 1991 to provide an institutional framework for the management and administration of the .jp <a href="javascript:void(0);" class="mw-lingo-term" data-lingo-term-id="a7bd4b3f417b16c430afe50d4c8ecff3">ccTLD</a>. In April 1993, with Jun Murai's consent, JNIC reorganized itself as JPNIC (JaPan Network Information Center).<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> </p><p>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.
