Go if you're a resident, wait if you're a tourist

I have never been to another Disneyland, so I don't have anything to compare Tokyo Disneyland to, but the experience was very good.
One thing that can really be appreciated about the developers is that they are very English-inclusive. Almost everything in the park is translated into English - rarely do you see an American park where signs flip every 15 seconds to display Spanish text. The only thing that isn't translated into English is audio, which may lead to English-speakers being confused on the Pirates story, but it shouldn't be expected - they've done so much already to cater to Americans, you can't complain about things not being translated.
The major downside is that it was very, very crowded when I went. The line for Splash Mountain lasted about 2 hours. Nevertheless, all of the rides are very well-maintained and very fun.
No matter what language you speak, you will have no problems at all in Tokyo Disneyland, but I would only recommend it if you live in Japan as I did. If you're just visiting, wait until you return to the U.S. to go to Disneyland or Disneyworld - take the time to visit actual Japan while you're there.
