Naomi Tamura and Himawari Gasshoudan is a Japanese group credit used for releases that present Naomi Tamura together with the Himawari Gasshoudan name. As a collaborative artist billing, it functions as a distinct catalog entry rather than a solo Naomi Tamura credit, which helps separate this material from other releases in discographies and music databases. The name is therefore best understood as a stable identifier for work issued under this combined artist presentation.
