I’ve noticed something in instrument but seems I cannot edit myself
in japanese, it should be 和太鼓 sortname ワダイコ
It’s called taiko only outside of Japan. In Japan they call it wadaiko (taiko is too general for them , wa daiko is for Japanese taiko, wa is generally for Japanese stuff).
In french maybe I would have expected taïko (with i trema), taiko was not yet in my dictionnary (Robert, 1979)
