Have you tried Kobe beef?  And if you have, are you sure it was real?  According to this story in Debonair magazine, you probably had American Wagyu. 

Apparently, the next big “beef” is Matsuzaka which is “produced from virgin female Wagyu cows, in a serene area along the Miyagawa river not too far from Kobe. They are fed plenty of fodder, tofu lees and ground wheat. When they have no appetite, they are fed beer to stimulate their eating, and they also receive regular massages with straw brushes after being sprayed with shōchū and are taken for daily afternoon walks. “
