about us

Overview

J-Stream Inc. was established in May 1997. We are the first company in Japan to specialize in streaming.

Not only do we maintain our own lines and infrastructure, but by partnering with broadband xDSL and CATV providers, major ISPs in Japan, data centers, CDNs and others, and supporting such major formats as Adobe®Flash®, Window Media®, QuickTime®, and Real Media®, we promote our line environment and terminals, along with a large-scale streaming infrastructure free of delivery system constraints. And we do more than just deliver content. Through our delivery performance and advanced operation technology, which is the best in Japan, we currently provide a full range of streaming-related services, including Website production.
