LOL, I think it depends on what nationality you are. For most Americans - including myself - I would disagree. Which is not to say TDR is not an incredible experience. It is just TDR was built more skewed to the locals just like DLR and WDW were built more skewed to Americans.
For diehard Disney fans a trip to TDR should be high on your list!
I would say once you are at the TDR you are going to do pretty good no matter what nationality you are or language you speak.
Sure language may be a slight issue, but I never felt uncomfortable about it when I was there. Even when staying in Tokyo itself.
Plus the parks are surprisingly cheaper than they are in the states.
Personally, I am a local to Disneyland, been to the TDR 3 times, been to WDW 8 times in my life, twice in the past 4 years. After my last trip to WDW my wife and I agreed we would give WDW a long break and just go to Tokyo again because the Disney and overall experience was way better.
TDR, things I took away from my visit
Cheaper prices than in the U.S. parks
Old Attractions that look like they are brand new because the upkeep is terrific
Parades and Shows that are better than anything they have here. However, the fireworks were pretty bad, but I hear they have a new night show.
Best Cast Members in all of Disney Parks
Great food
Great guests. You will barely hear a child cry, people yelling at each other, and strollers or wheel chairs being abused. Respect for yourself and others is huge in Japan. Plus they LOVE Disney
Tokyo DisneySea. Greatest theme park Disney has ever created
