About JORC’s establishment and its goal

We, Japan Orangutan Research Center (JORC) is a NPO that is led by ex- experienced zookeepers and researchers, established in 2016. The roots of the organization’s establishment can be traced back to 2004, when the NPO directors, who were graduate students at that time, established a wild orangutan research site in Malaysia’s Danum Valley Conservation Area. After that, researchers and zookeepers interacted with each other to share information and agreed to “do something immediately” for the critically endangered wild animal overseas and domestic captive animals. This group has gradually expanded and have created a place for people specialized in orangutans as well as for those with strong passion to do something for the orangutans. This NPO consists of four approaches to promote orangutan’s attractiveness and their latest situations.

Message from the Representative

Representative: Hidetoshi Kurotori

Thank you for visiting our website! Japan Orangutan Research Center (JORC) started as a voluntary organization in 2016 and with everyone’s hard work and effort, we were approved as a non-profit organization on June 7, 2019. We would like to express our gratitude once again to all those who have supported us. Our goal is to protect orangutan’s future, by spreading words about their endangered situation such as via deforestation and to spread interest and understanding for orangutans. Why not join us in thinking, learning, and supporting the orangutans to protect their future.
