This is probably too niche of a hobby, but that's what the seasonal boards are for right?
Anyway, linear television from around the world is available to anyone with a media player that can support playlists and an internet connection. It can be a fun thing to do when you're bored and having nothing to watch.
There's a lot of filler channels run by governments and stuff, but there's some cool and odd stuff as well. For example, even though I know little-to-no Japanese, Fuji TV usually is entertaining enough as the programming is usually positive. The J-sports channel have call-in shows about obscure sports late at night.

https://iptv-org.github.io/iptv/countries/jp.m3u are the Japanese channels, which is what Kissu will probably be most interested in.
https://iptv-org.github.io/iptv/countries/kp.m3u North Korea has some channels available too, as I know there's some interest in that here.
With how saturated mass media is these days, it surprised me that a lot of isolated, remote countries like the aforementioned North Korea or Mongolia actually have all their channels go off the air (or offline, in this case?) and I'm looking forward to seeing what the television in those countries is like.
