The story
JPRS came into existence out of a resolution at the 11th General Meeting of JPNIC, who had until then been managing the.jp domain. It was decided that due to the growing importance and complexity of the.jp domain, a separate corporation should be created with the purpose of running the registry.
In the period following the resolution, details were worked out, a structure was set up, and then on 2003-06-30, JPNIC, in co-operation with ICANN, transitioned the.jp domain to JPRS.
