Generation Checker
Select two members to compare their group generation, audition cohort, trainee generation, and debut year.
It is common for only one or two axes to match.

Not selected
“Same generation” can mean joining the same group generation, entering through the same audition, joining the same trainee generation, or debuting in the same year. Hello! Lab shows all four separately.
The audition axis includes people selected for a group or recruited as trainees through the same audition. Existing trainees who formally passed the same public audition are included; members selected through a separate trainee track or added outside it are not.
The result reflects the data currently available. An unavailable axis is not treated as proof that two members are from different generations.
