You probably know Actor’s School Hiroshima (ASH) from their stellar alumni. The performing arts school figures big in the idol community with graduates including PERFUME, Morning Musume’s Sayashi Riho, Babymetal’s Nakamoto Suzuka, Nogizaka46’s Nakamoto Himeka, and new idol unit Manaminorisa. “Japan GOOD!” looks like a very polished student group exploring their options by sending their product out in the world through their school’s connections. Other than this, precious little about this quartet can be gleaned without further investigation … which feels weird to me. If you want to learn more, here’s the ASH website. Otherwise, enjoy this promotional video.
