About This Site

Hello! Lab is an unofficial database for exploring Hello! Project members, groups, and generation relationships.

It separates “same generation” into group generation, audition cohort, trainee generation, and debut year so that the result does not hide important differences.

The site uses member-color circles instead of photos. Data is compiled from public information, and unverified fields are clearly marked. Please check each group’s official website for the latest information.
