The Winter 2017/18 edition of
Zoo Grapevine & International Zoo News has a brilliant, 12-page section on 4 Tokyo zoos and the large, full-colour reviews are ones that I've already read on several occasions. The magazine is a must-own for every zoo enthusiast and it is intriguing to hear of
@FunkyGibbon 's thoughts in relation to those written by Tim Brown in the magazine.
Ueno Zoo: There are plenty of rarities mentioned in the article, including Chinese Pangolin, Ryukyu Flying Fox, Sulawesi Tarsier, Aye-aye (the zoo had 10 of them a year ago!), Japanese Giant Salamander, Giant Panda, Shoebill, etc. Exhibit quality is apparently hit-and-miss, like most major urban collections, but Ueno Zoo is a must-visit establishment.
Tama Zoo: A big, 129-acre zoo with two of the finest insect houses in the world. "You will need at least an hour (or two) to properly appreciate Tama's outstanding invertebrate displays." A huge butterfly house, Insectarium, Glow-worm Cave, Mole House, Orangutan Skywalk, Koala House, plus tons of rarities never seen in North American zoos. I wish that I could visit tomorrow!
Inokashira Park Zoo: A zoo that surprisingly opened during WWII (1942) and I'm curious if
@FunkyGibbon will visit. The zoo has Tsushima Leopard Cat, which is "regarded as an island population of the Amur Leopard Cat (
Prionailurus bengalensis euptilurus).
Tokyo Sea Life Park: The huge Pacific Bluefin Tuna tank is famous and again there are apparently plenty of Japanese rarities that are never displayed elsewhere. There is an exhibit for a lot of penguins (25 Southern Rockhopper and more than 100 Humboldt's) and even Little Penguins in a separate exhibit.
