The photo of the title was taken at Ueno Zoo. Now panda twins born in 2021 live there. There are many wildlife parks all over Japan. For example, in the northernmost prefecture, Hokkaido, Asahiyama zoological park attracts animal lovers from all over the world. In or around Tokyo, I would like to recommend some facilities.
Tama zoological park in Tokyo has an attraction of Lion Bus. Tama zoo is the largest one in Japan. Zoorasia in Yokohama is characterized by "no barrier display". Both zoological parks are good for a picnic for families. Shinagawa Aquarium is easily accessible because of its location in the middle of Tokyo.
