NHK Plus is a video streaming service offered by NHK, allowing users to watch NHK's terrestrial broadcast programs online. The service offers a catch-up feature, allowing viewers to watch General TV and E-TV programs for up to 7 days after they have been broadcasted. This means that users can easily catch up on their favorite shows if they missed them when they originally aired.

In addition to the catch-up feature, NHK Plus also provides a playlist feature, which organizes TV programs by genre and theme. This makes it easier for users to find the programs they are interested in watching. The service also offers subtitles, bilingual broadcasts, and commentary broadcasts, providing a more inclusive viewing experience for users.

It is important to note that NHK Plus does not provide VOD service, simultaneous broadcasting, or rewinding play through the TV app. Some local programs may be available for up to two weeks, but not all programs can be provided through the service. The availability of NHK Plus is limited to Japan, as it is determined based on the customer's internet connection's IP address. It is also important to consider that charges may apply depending on the user's internet service contract. NHK Plus should not be confused with one-seg broadcasting, which is a different terrestrial digital broadcasting service.
