Autumn Music Festivals in Eastern Japan [2025–2026]

@JAM, which began with its predecessor event WotaJAM and has been sharing a variety of Japanese cultural phenomena—centered on idols and spanning anime, Vocaloid, and more—and Idol Yokocho, which started as a goods shop in Akihabara, both celebrate the 10th anniversary of their inaugural events in 2021. To commemorate this, the Akihabara Idol Circuit will be held as a collaboration event! Held in a circuit format, this modern live style lets you enjoy the performances at a relaxed pace without being overly crowded—perhaps a bit of a luxury these days. Since it’s a collaboration with the comprehensive official idol goods shop, be sure to check out the merchandise lineup too!

This music festival, held in Atsugi City, Kanagawa Prefecture—also known as a city of music—is a popular event drawing attention for featuring today’s hottest artists. It also hosts a newcomer discovery audition designed to support local performers, and the stage by the Grand Prix winner is a highlight. After the event, we recommend enjoying local gourmet specialties like Atsugi’s famous “Shirokoro” horumon (grilled pork offal). Since the lineup’s genres change every year, it’s an event that will make you want to come back again next time.

This is a city jazz event that makes the most of Yokosuka’s character as an international city—home to a naval port, surrounded by the sea, and with many foreign residents. With the aim of bringing everyone together in a friendly atmosphere while listening to music, it’s a music festival where participants can get excited as one through music, the common language that transcends borders.
