PlayStation 4 owners will receive a one month trial membership, after which they will need to update their accounts to the premium niconico account if they wish to continue using the service to live stream their games. For those unfamiliar, niconico is a popular streaming service in Japan which some have likened to Twitch and YouTube. It is mostly populated by gaming content, although in the past publishers have used the platform to stream events and announcements. In fact Nintendo even has some shares in niconico. Of course given that it is a Japanese service, chances are most of the content will be streamed In the Japanese language as well, meaning that unless you speak the language, chances are you might not understand what is being said.
