There is something which is pretty unique to Tokyo Disney parks, and it's what a friend of mine who shot recently the pictures below call "the Disney Couples". Basically, it's Tokyo Disneyland fans, whether they're just friends or lovers ( and they can be more than two ) who come to TDR parks dressed exactly the same way, with the same clothes, same hat, etc... often but not necessarily "Disney" outfits.
It may of course exist in others Disney Parks but in Japan, whether at Tokyo Disneyland or Tokyo DisneySea there are dozens if not hundreds of these "Disney Couples". It's cute, it don't hurt anyone, and it's the kind of thing so deliciously Japanese that we love it!
