What is OCN?
OCN (Open Computer Network) is NTT’s Internet access network, providing dial-up Internet access for ¥2,300/month for up to 15 hours (¥1/minute thereafter), or a dedicated 128 kbps ISDN connection for only ¥38,000/month, including all usage charges. The latter service, called OCN Economy, is ideal for those looking to setup their own e-mail and Web servers, and is the cheapest dedicated Internet connection service in Japan.
