No elephant deserves to live and die alone.

For more than 60 years, Hanako lived totally alone in a barren, concrete enclosure at Inokashira Park Zoo in Tokyo. Her tragic story captured hearts around the world and exposed the suffering that can come from keeping highly social elephants in isolation.

Hanako died in 2016, but her story did not end there. Her life inspired the creation of Elephants in Japan and a movement to ensure that the other elephants living as she had would not be forgotten.

Shining a Light on Solitary Elephants in Japan

Elephants are highly social beings who suffer greatly when kept in long-term isolation. Since the death of Hanako in 2016, Elephants in Japan has worked to document and improve the welfare of solitary elephants in Japanese zoos.

Our independent reports provide evidence-based insights, expert analysis, and concrete recommendations for change.

Solitary Elephants in Japan: Still Alone — A Current Assessment

Nearly a decade after our original report, we revisit the welfare of Japan’s solitary elephants to examine what has changed—and what has not. While some progress has been made, many elephants remain alone, and others have become solitary for the first time.
