Teru has spent 40 years living in this outdated zoo enclosure at Yuki Park Zoo in Kofu, Japan. She has been alone for 20 years in this concrete prison since the death of her companion Mimi in 2000. There is no shade. There is no companion. There is literally nothing. Teru shows stress via her non-stop repetitive swaying and bobbing.


“There is simply no justification for keeping elephants under these conditions.”

– Dr. Keith Lindsay, Elephant Biologist




Animal science students from a nearby university regularly started visiting Teru in late December 2017. Their observations helped implement new enrichment efforts at the beginning of 2018 to help end Teru’s stress-coping behaviour of rocking back and forth continuously. These efforts include a feeding challenge (a toy for mealtimes provided for Teru to shake to release food) and branches put on the ceiling of her enclosure. In March 2019, a sandbox was built for Teru which she loves to use.  The zoo also announced an ambitious and extensive refurbishment and expansion plan, which will include Teru’s enclosure as well.

The zoo also declared they will no longer exhibit elephants after Teru.

This is Fuko. She’s been alone for 12 years and spends most of her time in this tiny indoor cell at Nagano Chausuyama Zoo in Japan.  To cope with her impoverished conditions, Fuko paces in a meaningless repetitive pattern, over and over in her enclosure. Her pacing is an abnormal stereotypical behavior that is often seen in captive wild animals kept in substandard enclosures. They are often associated with boredom, anxiety, frustration and depression, and they mean that Fuko’s biological, behavioural and social needs are not being met.

Miyako the elephant has been kept alone at the Utsunomiya Zoo in Japan – for 47 years, alone. She was brought here from Thailand when just a baby: 6 months old. She exhibits stress via her stereotypical behavior, gripping and shaking with her teeth the steel bar in her outdated enclosure. Unstimulated by her barren environment, Miyako attempts to interact with zoo visitors.  But this old moat style enclosure is also dangerous. If she falls over into the moat, she could be seriously injured.

Write a letter to Miyako’s zoo:

SIGN and SHARE the petition to help Miyako. There is also a second petition in Japanese for Miyako which one of our followers set up. Sign the Japanese petition here.


We delivered Miyako’s petition in June 2018 with amazing +240k signatures! To-date the petition has gathered another staggering +100k signatures! The zoo has so far not replied to our follow-up letters, but we will not give up on Miyako and will deliver the updated petition to the zoo again soon. Thank you for your support!

Hamako – died 2022

Hamako has been alone for 12 years, since the death of her companion Miyo. Her outdoor enclosure at the Hamamatsu City Zoo in Japan has no shade for her in the hot summer heat. Her indoor enclosure temperature was only 9.3 celsius in the middle of winter with no heater. Hamako shows a stress-coping behavior of patterned pacing in her outdoor enclosure, with which she occupies her time until the next “feeding time”.


Hamako died on 15. September 2022. She was alone for 14 years at the Hamamatsu City Zoo after her close companion, Miyo, died in 2008. The zoo reports that Hamako became too weak to stand on September 14, then was found passed away the following morning. They are investigating the death, claiming it is likely due to old age.
