Ueno Zoo
In August 1943, the administrator of Tokyo, Shigeo Ōdachi, ordered that all "wild and dangerous animals" at the zoo be killed, claiming that bombs could hit the zoo and escaped animals would wreak havoc in the streets of Tokyo. Requests by the staff at the zoo for a reprieve, or to evacuate the animals elsewhere, were refused. The animals were executed primarily by poisoning, strangulation or by simply placing the animals on starvation diets. A memorial service was held for the animals in September 1943 (while two of the elephants were still starving) and a permanent memorial (built anew in 1975) can be found in the Ueno Zoo.
