Attribution matters.

Nine working Japanese breeder dossiers are recorded for source-by-source review. Inclusion is not a ranking, endorsement, or verification of any claimed creation. A broader 50-breeder candidate list is not a verified top-50 list.

Additional detailed breeder dossiers and unverified genealogies remain unpublished while source and photo-rights reviews are incomplete. A seller listing never proves a strain was created by that seller.
