O.Y.Z NO YAON (Oyaji no Yaon) | Music Festival / Event
Since this event is called “O.Y.Z NO YAON” (= Oyaji no Yaon) and held at Osaka Castle’s open-air stage, the lineup consists only of adult male groups. Even though they’re ‘oyaji’ (middle-aged men), I’m sure each group will show off a mature coolness that won’t lose to the younger crowd.
