For some, it’s hard to think of AKB48 without thinking of their iconic music video for “Heavy Rotation”, which at the time of this writing has 140 million views on YouTube alone. The video shows the members of the time wearing lingerie in a slumber party setting. There’s also the yearly music videos taken on beaches with the members in bikinis such as “Everyday Kachuusha” and “Ponytail to Shushu”. But now the rumor is that AKB48 will be limiting these types of outfits for their younger members, at least as far as gravure goes.
Themed idol groups are nothing new, as a matter of fact they make up much of the idol scene as we know it today. Let us not forget that arguably the biggest idol group right now, BABYMETAL, is the product of a theme on paper put into real life. With this in mind we now have "Kaso Tsuka Shojo" or "Virtual Currency Girls", a cryptocurrency-themed idol group.
