Chiba Festival Calendar [2026]: A Roundup of Music Festivals and Outdoor Events

We’ve put together a list of music festivals in Chiba Prefecture, including summer festivals, rock festivals, and outdoor festivals.We look forward to welcoming you again this year at exciting events like PUNKSPRING, JAPAN JAM BEACH, and SUMMER SONIC!

Chiba Prefecture

JAPAN JAMSat 5/2–Tue 5/5, Chiba Prefecture

This event had been held as JAPAN JAM BEACH until 2016, but due to facility constraints at Makuhari Seaside Park, the venue, we relocated starting in 2017. The new venue spans roughly 50 hectares, and the grounds where the stages are set up are adjacent to each other, allowing for a compact layout. What’s more, it has become a truly groundbreaking urban festival, just an 8-minute walk from the nearest station!
