The world's second largest aquarium - 沖縄美ら海水族館 Okinawa Churaumi Aquarium.

Measuring 8.2 by 22.5 metres with thickness of 60 centimetres, capacity of 7,500 cubic metres for this monster tank. My 18-55mm just can't fit everything inside.

Just imagine how huge are they, and how smart are we. Amazing!

Autumn in Japan.
