Abstract: The Japanese Virtual Observatory (JVO) is a web portal for astronomical data and analysis system, and utilizes the standards developed by the IVOA to communicate with the VO-compliant resources in the world. We started official operation of the JVO in March 20087. The JVO provides the following web-based services: 1. search for VO-compliant data services in the world, 2. search and access to astronomical data through standard VO interfaces, 3. use of on-line astronomical analysis tools, 4. on-line data reduction for the Subaru telescope, 5. use of data storage on the JVO system. We also operate several VO data services (SkyNode, SIA, SSA) and a publishing registry. As of 22 January 2009 over 1,900 resources in the world are registered to the JVO portal. More than 40,000 pages are requested from the JVO system every month. 1.6TB of data have been downloaded since the start of the official operation. A GRID computing system was introduced to provide a massive computing resource for reducing the data obtained by the Subaru telescope. In the initial operation, we offer 48 CPU cores, 4GB memory per core, 1TB of locally attached hard disk and 100TB of NFS storage area in the GRID computing system.
