Kanto’s Popular Music Festivals [2026]: A Complete Guide to Spring, Summer, Autumn, and Winter Outdoor Events

Gojappe Music Festival is a circuit event held in Hitachinaka City, Ibaraki Prefecture. “Gojappe” is a dialect term from the northern Kanto region that roughly means “careless” or “slapdash,” and the idea is that on this day, people forget their everyday burdens and let themselves be gojappe to have fun. The venues are bars, cafes, and similar spots.

Six artist acts will perform live across six venues in five bars of the GULLIVER Group. Unlike a typical circuit event, each artist stays at a fixed venue and plays two to three sets with breaks in between. Attendees move from venue to venue to enjoy the shows. The event runs from 6:30 p.m. to 11:30 p.m., so you can relax and enjoy food, drinks, and music at your own pace.

This is a music event organized by Animax, famous for the catchphrase “If you watch anime, watch Animax.” The lineup is impressively far-reaching, featuring not only popular anime voice actors but also bands and idol units connected to anime. The event began in 2009 and has been held annually at Yokohama Arena since 2010. Watching fans wave glow sticks creates an undeniable sense of unity!
