As a new festival organized by Ibaraki Broadcasting, the LuckyFM Green Festival has been held since 2022.

Featuring local ingredients and a wide range of art and music genres, it’s also recommended as a family-friendly event. It’s sure to become one of your favorite summer memories!

This jazz festival is held under the concept of preserving and nurturing the local jazz culture, focusing on jazz musicians living in Hokkaido who are active in the local scene year-round. The venue is Otaru, an excellent location that perfectly matches the atmosphere of jazz.
