Autumn Music Festivals in Eastern Japan [2025–2026]

Did you know there’s a vast green open field in Tokyo? It was used as a venue for the Tokyo Olympics, and its area is said to be roughly the size of 10 Tokyo Domes. It hosts Tokyo’s largest outdoor festival, packed with things to enjoy—music, camping, gourmet food, fireworks, and Tokyo’s night skyline. As a camp-in festival, you can even bring your pets and spend time together, and if you choose a campsite in the music area, you can enjoy the stage right from your own tent. It’s the kind of event you’ll want to join every year as a summer festival to make family memories.

This event is a long-standing jazz festival that has been held since 1993 under the slogan “The entire city becomes a stage.” Taking place in Yokohama—a historic port city and arguably the birthplace of jazz in Japan—it attracts 100,000 visitors every year, making it one of the largest jazz festivals in the country.
