What the thing is
Wagyu is a legal and zoological category—not a style of beef. It names four Japanese cattle breeds, not a marbling standard or cooking method.
Where it came from
It emerged from late-nineteenth-century crossbreeding of regional native Japanese cattle—including Mishima and Kuchinoshima—with imported stock, then crystallised as four closed breeds via selective breeding.
What it gets right
It correctly identifies four distinct Japanese cattle breeds developed through documented regional selection and closed breeding. It anchors the term to biological lineage and national rearing—not just taste or texture.
What it gets wrong
It misleads outside Japan by allowing ‘Wagyu’ to label beef from non-Japanese cattle of those breeds—even when raised elsewhere, fed differently, and lacking sashi or aroma. The term is geographically unmoored in export markets.
Why it matters now
Because ‘Wagyu’ is used globally on beef with no Japanese origin, no sashi, and no regulatory oversight—eroding the meaning of terroir, breed integrity, and consumer trust.
Is it worth your time
Yes—if you care about precise language, food labelling, or how global supply chains obscure origin. No—if you assume ‘Wagyu’ guarantees marbling, flavour, or Japanese provenance.
