The fun part of this aquarium in southwestern Tokyo is walking through an underwater glass tunnel while some 450 species of fish swim around and above you. There are no pamphlets or explanation panels in English, however, and do your best to avoid Sunday, when the dolphin and sea lion shows draw crowds in impossible numbers. Take the local Keihin-Kyuko private rail line from Shinagawa to Omori-kaigan Station. Turn left as you exit the station and follow the ceramic fish
on the sidewalk to the first traffic light; then turn right.
