The Yomiuri Shimbun A huge water tank called Sony Aquarium 2019 is showcasing fish such as those from Okinawa for the enjoyment of shoppers at Ginza Sony Park in Ginza, Tokyo. The floor of the tank measures 5 meters by 1.8 meters, and the water is 1.5 meters deep. There are about a thousand fish of 30 different species swimming around, including a 90-centimeter-long humphead wrasse — commonly known as the Napoleon fish — that was brought from Okinawa Churaumi Aquarium in Okinawa Prefecture. “It looks cool and beautiful,” said 7-year-old Aoi Katakura, who came from Maebashi. The exhibition runs from 10 a.m. to 10 p.m. daily through Aug. 18.
