List of summer festivals in Eastern Japan held during summer vacation [2025–2026]: Rock festivals and outdoor music festivals

This is an idol festival held in Roppongi, where TV Asahi is located. Since there’s also a popular music program that features idols, you might discover fresh idols before they truly explode in popularity. It’s a recommended festival for fans of idol culture and for fans of “kawaii” culture.

MURO FESTIVAL is a fest hosted by Shibuya O-Crest. At a time when people say audiences are drifting away from live houses, it was launched to create opportunities for bands active in live houses to perform outdoors and give back to the live house scene. This year it will be held indoors, combining the best of Muro Fes with the appeal of live houses.

Nango Summer Jazz Festival. Not only can you enjoy performances by many artists, but Nango, where the event is held, is also a famous tourist destination, and it offers local specialties such as Nango soba and blueberries. It seems you can camp at the venue from the night of the event until the next morning, so it would be nice to enjoy the jazz festival for a full day, stay overnight, and spend the second day sightseeing in Nango.
