Nights of Wonder (2015)

The aquarium at Kasai Rinkai Park extends its opening hours for four days over the Obon holidays, letting visitors take a look at the nightly activities of marine creatures from giant tuna to penguins. The aquarium lighting will be toned down, making for a mysterious atmosphere, and special guided tours will also be taking place. Finally, as is customary when it comes to summer events, a beer garden will be on hand to entertain easily-bored adults.
