摘要：The Japanese Virtual Observatory (JVO) is a web portal to various kinds of astronomical resources distributed all over the world. We have started its official operation of the JVO portal since March 2008. The JVO provides seamless access to the Virtual Observatory (VO) compliant data services, and also access to the reduced data observed with Subaru telescope and on-line data reduction system for Suprime-Cam instrument of the Subaru telescope. The system implements standards of the International Virtual Observatory Alliance (IVOA) to communicate with the VO components in the world.
