NX-Jikkyo is a real-time communication service that allows everyone to comment and share their excitement about currently broadcasting TV programs and events.
Comments posted on Niconico Live will also be displayed in real time.
The past log playback function allows you to play back all past logs from November 2009 to the present by specifying the channel and date/time range.

Alone, but not alone.
Although the TV image will not be played, you can enjoy watching your favorite program on TV and enjoy the comments that are played on the player.
Please feel free to comment and share your thoughts.

To post comments on Honke Niconico Live, you need to link with your Niconico account. You can also post comments to NX-Jikkyo's comment server by switching the comment posting destination in the settings (no login required).
Account information and access tokens obtained during linkage are only saved in the Chrome browser cookie (NX-Niconico-User) and are not saved at all on NX-Jikkyo's servers. Please rest assured.

The past log playback function allows you to play almost all past log comments from November 2009 to the present, which are stored in the Niconico Jikkyo past log API (https://jikkyo.tsukumijima.net).
The huge amount of past log data spanning more than ten years is engraved like a time capsule, with the ``real voices'' of those who lived at that time, which strongly reflect the social conditions at that time.
Why not take a look at old comments once in a while and feel nostalgic, or enjoy recorded programs with comments?
