5. NMB48
One more sister theater idol girl group. Ok, this will be probably hard to repeat more times than one. The group follows the same concept of “idols you can meet”, releasing two albums that topped the charts.
Overall score:9
4. Momoiro Clover Z
This girl band holds a record of nearly a half a million people attending their concerts in 2014, which the highest record for all female performers in Japan. After their number one album in 2013, they are currently working on a two-part follow up to be released in 2016.
Overall score:12
