The people of Japan live in a society that's under the dictatorship of Manbushi Masaji. Most songs and music genres are banned because song is merely a way to force the people to worship the leader and their family. Music isn't created with heart or soul. This ban on music was struck down more than a decade or so ago.
A third world war happened recently as well, ending only twenty years ago. Japan seemingly came out victorious, benefitting from the war. Who they fought against is not stated. Due to the war, the technology of Japan rapidly advanced, leading to where it is now in 2025, where humanoid robots roam the land.
