宮崎俊博物館 tickets need to be purchased in advance. In HK I bought it at JAL travel - Select Travel. It is located at Harbour City TST.
Another place I would recommend is an aquarium located just a JR stop before Disneyland. It is known as 葛西臨海公園. The environment is pleasant since it is by the bay and able to see Disneyland from a distance.
