For more than 60 years, Hanako had lived in a tiny concrete enclosure at Inokashira Park Zoo in Tokyo, Japan. Her enclosure had no grass or trees, and she hadn't seen another elephant in decades.
Her plight came to light late last year when a visitor, appalled by her condition, wrote an online post calling Inokashira Park "one of the cruellest, most archaic zoos in the modern world."
The tourist, Ulara Nakagawa, said Hanako "just stood there almost lifeless - like a figurine." Videos show the elderly elephant swaying back and forth, a form of stereotypic behavior, blending in in to the stark gray walls behind her.
