Kpop, from what I've gathered, is pretty popular in Japan. But will the rise of Niziu, an all-Japanese group with a kpop sound cause it to explode in popularity?
Niziu is everywhere over there. That means even non-kpop Japanese fans probably have heard at least one of their songs and if enough people are interested in the sound, could it cause an even bigger Hallyu wave?
Warning, I am not Japanese, I am just speculating as a fan of Niziu. This could be a total reach. If a Japanese fan would like to add something, please feel free.
