It may be very tender and moist, but the way the Japanese produce Kobe beef is absolutely "cruelty to animals" to the lowest degree. The cow is never allowed to take one step in it's entire life. It kept penned up so that it can't move. Instead, the caretakers massage the legs, and body of the cow to maintain muscle tone, but not enough to cause the muscle to become tough. I would not buy Kobe beef if it were a dollar a pound. I can't see anyone treating an animal that way just for the purpose of satisfying rich people palates with tender, moist beef.
As long as you are not some PETA type with an attitude, the beef producers are proud to show you how pampered these animals are. The "can't move" stuff is total poppycock-- moderate exercise is a must for developing muscle tone. While it is true that their living quarters and pastures are rather cramped compared to their American counterparts, they are also smaller and stouter than their American counterparts.
I've also toured Japanese dairy farms and the situation is similar-- smaller pastures (in some cases, individual paddocks), top quality feed (one load of grain rejected for impurities was actually sent to another country for human consumption) and individual records of health check-ups, milk production, etc.
