Abstract: We developed the first prototype toward a Japanese Virtual Observatory (JVO) by using the Globus Tool Kit 2 (GTK2). We found that the system worked as we had expected, including the functionality of JVO Query Language. However, it took a very long to initiate each Grid process. Thus we replaced the GTK2 with a tool distributed by NSF Middleware Initiative, and shortened the polling interval of the job-manager from 30 seconds to 3 seconds. As a result, the serious problem was partially resolved, and the elapsed time for a query reduced to about half of the previous one.
