japanese pop culture in general is a great reminder that the world isn't as culturally flattened out as you think. To western eyes/ears the logic of it is pretty unfathomable
Yeah I guess it is the extremeness of it - mainly that I can't understand how a video like that one is the video for a smash chart hit. It's so far from anything that would be considered acceptable in the UK or US. Obviously that kind of intensely surreal sensory overload thing is familiar to us, but not in the mainstream
