Happy Music Project is a Japan-based project organization founded in September 2011 with the aim of filling the world with enjoyable music. Bringing together professionals from diverse fields, it develops music, video, and event projects, generally taking a concept-led approach while also creating projects for clients. Its work includes participatory music events, concerts, workshops, music video production, and film production.

A central initiative is Gospel Festival, a community-participation event open to anyone who loves gospel music. The project also organizes Gospel College, offering vocal and gospel workshops focused on learning in greater depth and enjoying the music; Gospel Koshien, a nationwide gospel music competition open to public applications; and Gospel Music Info, a site sharing news about gospel groups, events, and related topics. Its festivals include the long-running Yokohama Gospel Festival and Ebisu Gospel Festival. Happy Music Project develops and produces engaging music-related experiences and welcomes inquiries from people interested in its activities or potential collaborations.
