Kamogawa Sea World of Chiba prefecture is the complete sea leisure center. The program is constructed so that we can see some show of dolphin, grampus, white dolphin and sea lion in order. We passed one day happily, moving efficiently between the near halls. In the portion of an aquarium, exhibition of the freshwater fish reproducing the mountain torrent and the saltwater fish in a large-sized pool are devised in exhibition. I was able to take photos like their poses in natural field. There is a corner which the back yard of an exhibition tank can also inspect, and many floodlights, reflective luminaires for high ceiling, were used on the water surface of a tank.
