With a coalition of a dozen citizen groups and hundreds of individual members, JATAN effectively used research and public education to publicize Japan’s role in tropical forest destruction. Timber from the South Seas, a report co-authored by Kuroda, provided the first comprehensive data on Japan’s timber consumption patterns and exposed Japanese corporations’ contribution to rainforest destruction. It also outlined an alternative, positive role that Japan could play. Widely distributed in Japan and abroad, the report has increased international scrutiny of Japan’s policies and practices.
Kuroda met with the presidents of major corporations to encourage corporate responsibility and brought inhabitants of the rainforests and Japanese decision-makers together. As a result, the Japanese government has apologized to indigenous groups, and more than 40 local governments in Japan have introduced steps to reduce tropical timber consumption. As Japan is rapidly increasing its demand for wood products from non-tropical countries, Kuroda has expanded his focus to deal with temperate and boreal forest issues in other countries such as Canada, Chile, and Australia. His work has also included the global paper and pulp industry and plantations.
In 1998, Kuroda received a three-year research fellowship with the Institute for Global Environment Strategies to examine underlying causes of forest destruction in the Asia-Pacific region. His work influenced the Intergovernmental Forum on Forests. Kuroda remains active in JATAN as a board member.
