Hiroshima, a group whose music falls between R&B, pop, world music, and jazz, has long had its own niche. The band integrates traditional Japanese instruments into their musical blend and has generally been both commercial and creative within its genre. Hiroshima's founding members are keyboardist Dan Kuramoto (who also played shakuhachi), June Okida Kuramoto on koto (a key part of the group's sound), Johnny Mori on taiko drums, and Danny Yamamoto on drums, percussion, and taiko.
