Here's a new article described Hamura zoo ( Hamura city, Tokyo ) . This is the first time I visited there.

I visited Sumida Aquarium (Sumida-ku, Tokyo) which is at foot of TOKYO SKY TREE. The facility has one of the largest indoor, open pool-type tanks in Japan, exhibits of penguins.

I visited "Tokyo Tower Aquarium". There're no mammals, but we can see 50,000 fishes here.
