An aquarium in Tokyo will offer visitors the chance to view penguins in an overhead tank on the rooftop of a nine-story building.

The new attraction, opening at Sunshine Aquarium in the Ikebukuro district on July 12, will allow visitors to view surrounding high-rise buildings through the tank.

An official said no other aquarium in the world offers such an overhead penguin tank, adding, "We hope the view of penguins swimming in the city sky will help visitors to forget the summer heat."
