ELI5: What is so special about kobe beef, and why european or american herds can't produce it?

A cow is a cow?

Just like there are different breeds of dogs, there are different breeds of cows.  Kobe beef comes from a Wagyu cow.  European or American farms can't produce it because Kobe beef comes from Kobe.  If it doesn't come from Kobe, it's not Kobe beef.  Same thing applies to Champagne.  Champagne is a region in France.  Sparkling wine from other regions is simply called "sparkling wine".  Also similar is Scotch.  If it's not from Scotland, it can't be called scotch.  Other places produce the exact same thing, but they call it whiskey or bourbon.

American and European farms DO produce beef from Wagyu cows.  But they can't call it Kobe beef because it's not from Kobe, so they call it Wagyu beef.

Wagyu cows are known for high amount of marbling on the meat.
