Youko Tamaoki & Yumi Higuchi is a Japan-based collaborative artist credit used for recordings released under both performers’ names. In discographies and music databases, the shared billing works as a single entry, making it easier to track releases, appearances, and special projects without splitting the credit into separate artist profiles.
By keeping the original joint billing intact, Youko Tamaoki & Yumi Higuchi reflects a common practice in Japanese popular music: one-off partnerships are listed under a shared name while still crediting both performers in one unified profile.
