Chubbiness

 was a group under Avex.

The group was created following the Avex x CanCam fashion magazine collaboration audition held in Summer 2013. They picked all 10 members from 3500 applicants from all over Japan to create Japan's first "marshmallow" idol group, Chubbiness.

Their motto and catchphrase were "Chubbiness, be happy!". Their goal is to help people to accept and like their body as it is, and show Japan's very strict body type standards that girls (and everyone else) can be chubby, cute and happy.

All members graduated on March 9, 2019.
