hoshiotoSat, 5/23 Okayama Prefecture

Hoshioto is held in Okayama Prefecture. Taking place in the nature-rich city of Ibara, Okayama, as the event title suggests, once night falls you can enjoy a collaboration of beautiful starry skies and music. At hoshioto in 2016, it’s said that a very beautiful starry sky was visible during Sawagi’s headlining set. We’re praying for good weather again this year!

KITASAN ROLLINGSunday, 5/24, Ibaraki Prefecture

This rock festival started in the spring of 2023 to energize the North Kanto area. It brings together must-see and supportive artists who fire up the crowd with their performances—an essential part of any music festival. It’s a new-style event that rotates its venue each year among Ibaraki, Tochigi, and Gunma prefectures, and we’re also focusing on the market aspect so it can become an event cherished by the local community. As with any great fest, you can indulge in popular local foods and take part in workshops—unique experiences you can only enjoy here.
