48th Sony Aquarium

Ginza's Sony Building again plays host to this annual pop-up aquarium, which will see tropical fish and even a couple of tawny nose sharks brought to the capital all the way from Okinawa. When you're done admiring the strange specimens, head over to the exhibition floor for a look at a life-sized whale shark model and related video, or just hang out at the ground-floor Pub Cardinal and enjoy the tropically inspired food with some Okinawan beer.
