Shinagawa Aquarium しながわ水族館
The ward's own aquarium since 1991: tunnel tank, dolphin shows, 1,350 yen
Opened in 1991 by Shinagawa Ward inside the public park facing the sea (しながわ区民公園), it is a municipal facility distinct from the newer and better-known Maxell Aqua Park in Takanawa, which is in another part of the city with a different private operator. The stated theme is ‘encounters with the sea and rivers’: the underwater tunnel tank and the daily shows of dolphins, sea lions and seals have remained the main attraction for more than thirty years. In 2026 the aquarium turns 35 (5 October).
