Don't worry about it. Kobe beef, the real stuff, is awful. Typically 40-50% fat. I couldn't eat it.
I've had it. The real stuff, in Osaka, Kobe's neighbor city. My wife's uncle Akio (dear, dear man, may he RIP), took us and all the gaijin relatives to all the most expensive restaurants in Osaka. $300 a plate places, where he'd take us and his own Japanese extended family, at least 20 people total. Uncle Akio had some money
And he took a liking to me, and me to him. He really was a dear man. So I had a place of honor at the table next to him. When he noticed that I was less than enthusiastic for items like raw soft-shell crab, still in the shell, he asked me what I liked. My dear wife piped up with "he loves beef". So I got a plate full of genuine Kobe beef. Tender? Yes, very. But as I said, about 1/2 fat. I'm one who, for health reasons, trims all the fat off any steak or piece of beef I'm served. That's kinda hard to do with just chopsticks
So I had to eat it as is. It wasn't terrible, but I would have preferred a nice lean piece of steak.
I also saw it in raw form, in boutique grocery stores in Osaka. Broad range of prices, depending on quality, up to $100 for 200 grams. In raw form too, you can see it's nearly 1/2 fat. The more expensive, the more fat.
If you've had "Kobe" beef and it wasn't 1/2 fat, you haven't had Kobe beef.
