Recently there was a very peculiar event with the idol group Nippon Wachacha (formerly known as Nippon no Virus and then you can imagine why they changed the name of the group).
The event had the idols wearing bikinis while singing and dancing with a blouse on top. Those who witnessed the show took pictures and recorded videos that when you look at it it looks like it was a very erotic thing even.
Check out the photos and videos taken by nerdy fans below:
Check out the video of the presentation below, all the idols wear the huge white blouse but apparently only the one in the middle that is in a bikini.
