Youko Tamaoki & Yumi Higuchi is a Japanese collaborative artist credit used for recordings released under both performers’ names. In music databases, release catalogs, and discographies, the shared billing functions as a single entry so the credit can be tracked without separating the two names into different profiles.
Because it preserves the original release credit exactly as it appears, Youko Tamaoki & Yumi Higuchi makes related recordings, appearances, and special projects easier to identify and attribute. As a Japan-based credit, it reflects a common practice in Japanese popular music, where joint billing is used to distinguish one-off partnerships from solo work while keeping both performers visible in one unified profile.
