Along with Hi-Vision, described in other pages, data broadcasting is one of the most useful services made possible by the digitalization of broadcasting. Data broadcasting allows viewers to access news, program listings and other information on-demand. As a public broadcaster, NHK developed this service around the core concepts of "lifestyle convenience and enrichment" and "emergency preparedness."

NHK General TV data broadcasting carries not only local news and weather, but events and traffic conditions. It provides a valuable source of information to enrich the lives of members of the community.

Data broadcasting on NHK Educational TV provides useful information related to health, lifestyle and nursing care, while offering fun-to-use quiz functionality for kids.

For BS satellite data broadcasts, national news and weather, sports and business news are featured, along with in-depth information about drama and other series to enhance viewers' enjoyment of programming.
