Wagyu vs 'wagyu' — the trademark and provenance question
Globally, the term 'wagyu' is widely used and not consistently protected. Japan's 'JAPANESE WAGYU' logo (operated by the Japanese Wagyu Beef Export Promotion Council) is the official mark for genuine Japanese-origin wagyu. Australian wagyu, US wagyu, and other crossbreeds are different products — F1/F2/F4 crosses with Angus or other breeds, with different fat profiles and pricing.
Buyers should be specific about provenance: 'Japanese-origin certified wagyu' (Kuroge Washu / Akage Washu / Mukaku Washu / Nihon Tankaku Washu, the four official breeds) vs 'wagyu-influenced' Australian/US product. The price differential is substantial — Japanese A5 is multiple times the Australian A5 equivalent.
