Wet day so lazed around the hotel and checked our emails. Went to the aquarium and saw spectacular fish from all over the world including porpoises, a whale shark and huge Japanese crabs. We were also entertained by otters, dolphins and penguins, all of which were well practised at playing to the crowds. The aquarium was very well designed and we went deeper under water as we walked round. After the aquarium we had some lunch in an italian cafe and then went to watch a 3d film at the Imax cinema. The 3d effect made me rather queasy.

Went to look around Den Den Town which is the electronics district and saw millions of tiny devices on sale in a bizarre jungle of overcrowded shops. Some had as many as six floors of electronics on show all piled on top of each other haphazardly. Found some interesting Bowie bootleg CDs in a tiny shop but little else.

Very wet night so stayed in hotel and eat Chinese food and watched TV and wrote our postcards.
