Past events

Tama Music FestivalSat, Jan 17 — Kanagawa Prefecture

The cozy, community-driven music festival created by Tama Ward residents began in 2011. It’s held to provide a stage for artists active around Tama Ward and to boost local vitality and交流 through music. Participating artists cover a wide range of genres—jazz, brass band, dance, rock, pop—offering programs that people of all ages can enjoy. It’s a wonderful environment where local children can grow up familiar with music and have the chance to perform on stage. We hope you’ll join with your family!

The lineup features buzzworthy artists from a variety of genres, including dance music and rock—not only from Japan but also special guests from overseas. It promises to be a special experience that makes you feel as if you’re at an international event while staying in Japan.
