Japan activity score
No. 220 of 241 groups with recorded activity in Japan (top 91%)
- 0Japanese releases
- 0Japan-related tracks
- 1Members 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.
