The new additions include Tokyo Ska Paradise Orchestra (commonly known as Skaparadise), the legendary ska band that's been a cornerstone of Japan's music scene since 1988. Solo artist Hiroji Miyamoto, former frontman of The Elephant Kashimashi, also joins the bill alongside rock band Queen Bee (Jyoou-bachi), known for their theatrical performances and unique sound.

The festival will also feature boy group M!LK, the six-member unit under Stardust Promotion, and newer acts iLiFE! and ME:I. ME:I, the girl group formed through the survival show "Produce 101 Japan The Girls," represents the current wave of Japanese idol groups making their mark.

JAPAN JAM has established itself as one of Japan's premier music festivals, consistently bringing together established veterans and rising stars across multiple genres. The Chiba venue provides ample space for the festival's ambitious four-day format, allowing fans to experience a wide range of Japanese music acts.

With this diverse mix of ska legends, rock veterans, idol groups, and emerging artists, JAPAN JAM 2026 continues its tradition of showcasing the breadth of Japan's music scene. The festival promises to offer something for every type of music fan, from long-time followers of Japanese music to those just discovering the country's rich musical landscape.
