Fullblood Wagyu

100% genetically pure wagyu cattle with traceable Japanese lineage.

Fullblood wagyu have both parents registered as 100% wagyu with documented Japanese ancestry. This is the only way to achieve Japanese-level marbling outside Japan. Fullblood is distinct from "purebred" (93.75%+) and "percentage" (F1, F2, etc.) wagyu.
