KPOP DISCOVER's JO1 note

With JO1 the roles of the 11 members read better from the performance videos than from the music videos alone. Moving from INFINITY through Born To Be Wild, SuperCali and Tiger shows a group changing expression from song to song while holding the density of its formations.

Because the Japanese releases are numerous, there is no need to follow everything from the start. Fixing four points first, the debut, a signature piece of group choreography, the singing, and the fifth-anniversary period, then widening into the special editions and albums that hold a song you liked, is the shortest route.

Editors' take The group choreography of 11 members shows its development the more the performance videos are followed in sequence.

Japan activity score

KPOP DISCOVER original metric
No. 1/ 241 groups

No. 1 of 241 groups with recorded activity in Japan (top 0%)

  • 50Japanese releases
  • 167Japan-related tracks
  • 11Members from Japan
  • 0Official Japanese accounts

The denominator is the 241 groups, out of 564 covered by KPOP DISCOVER, whose raw score reaches at least one point. The score adds 10 points per Japanese-market release, 3 per Japan-related track, 12 per member from Japan, and 8 per official Japanese account. Japanese-market releases carry the most weight because they are the most direct evidence of activity; related tracks add track-level detail; members from Japan stand for Japanese-language communication and continuity; official accounts stand for a permanent point of contact. The weights are an editorial judgement, not a statistical optimisation, and the ranking tracks release volume in Japan closely.
