O.Y.Z NO YAONSun, 10/19, Osaka Prefecture

This event, “O,” which will be held at Osaka Castle Open-Air Music Hall.

Since it’s “Z NO YAON” (= Oyaji no Yaon), the lineup consists exclusively of adult male groups. Even though they may be “oyaji,” I’m sure each group will showcase a mature coolness that won’t lose out to the younger crowd.

Schedule	Sunday, October 19, 2025
place	Osaka-jō Hall (Osaka Castle Music Hall), Osaka City, Osaka Prefecture
