This 15-member idol group was started by Shintaro Yabu, chairman of the prestigious “West Japan Hamburger Association”. So, it only makes sense that he would start a group based around something he’s clearly passionate about, hamburgers. Yes, they sing and dance and it is all based around hamburgers. In fact, each group member represents a hamburger ingredient and wears it on their head during the performance. These range from the mundane, pickles and tomatoes, to the more bizarre, Awajishima fish and eggplant.
