The sea serpent topiary above sits to the right of Cinderella's Castle, approximately in the same spot as Anaheim's Snow White Grotto. Tokyo does have a Snow White Grotto, but their's is located to the left of the castle, approximately in the same spot as Anaheim's Plaza Gardens.
It's difficult to tell from just looking at the photo above, but the grotto and wishing well sit between the castle and Westernland (Frontierland). As an interesting side note.....neither Tokyo Disneyland or Disneyland in Anaheim list their Snow White Grotto as attractions. Hong Kong Disneyland however, does list their grotto as an actual attraction. My guess is that they do this because they are SO lacking in real attractions (their only "E" ticket-type attractions are Space Mountain, Jungle Cruise and It's A Small World) that they have to really stretch to come up with some way of making people think there is actually more to do in that park than there really is. After all, Hong Kong Disneyland also lists their "island" attraction and their "rafts to the island" as two separate attractions. To me that just WREAKS of desperation. Poor Hong Kong Disneyland! As an additional side note....neither Disneyland Paris or Walt Disney World have a "Snow White Grotto."
