In which country was karaoke invented?

Karaoke originated in Japan, which is one of the three great inventions in Japan (instant noodle drying method, animation, empty ォケーストラ, that is, karaoke). Due to Japanese customs, if a man comes home too early, his neighbors will look down on him and think that he doesn't even have entertainment every day, and he will go home too early every day. Later, they thought they should find something new to kill time. They use simple things such as TV and microphone to drink and sing in the bar. Later, with the development of science and technology, it evolved into today's karaoke.
