Regular TV in Japan has a variety of shows and movies broadcast every day.
From American movies, Korean dramas, variety comedy shows and language lessons.
If the show was originally from overseas they often have Japanese dub and subtitles.
Another cool feature is the ability to change the audio back to the original while watching it.
And that’s not just on paid services or cable, your ordinary TV channels and remote have this function.
It’s called 音声切り換え・おんせいきりかえ・onsei kirikae.
It literally translates as audio or voice change.
