In "Shinagawa Aquarium" located in Shinagawa Ward, Tokyo, approximately 450 kinds of sea and river creatures such as dolphins and deep-sea fish are raised.

In the corner of the Denki Wanni living in the Amazon River in South America, before Christmas, Christmas trees that are lighted up by discharge are decorated and entertaining children.

In addition, "Kotatsu" is set up in the dolphin corner, and visitors can watch the dolphin show through the glass of the aquarium while warming up.

A girl from a grade 3 elementary school visited from Chiba prefecture said that he was very surprised to see the fish generating electricity. Also, a woman who used the kotatsu in his family said, "I was glad I could see the show in a warm place."

Winter events of "Shinagawa Aquarium" are held until the 25th of next month.
