Dr. Nobuaki Ochi
Dr. Nobuaki Ochi is an Associate Professor at Toyo University in Japan and a leading advocate for light pollution reduction and dark-sky conservation. Holding a Ph.D. in science, he began his academic career in cosmic-ray physics before expanding his work into environmental education, light pollution, outdoor lighting, and the protection of starry skies. His research and outreach activities have played an important role in connecting astronomy with broader environmental and community-based approaches to nighttime conservation.
Dr. Ochi has been actively involved in the dark-sky movement in Japan for many years. As a former representative of the International Dark-Sky Association Tokyo Chapter, now associated with DarkSky Japan, he has contributed to public education, scientific research, and local initiatives aimed at reducing unnecessary artificial light at night. He has also supported the development of several internationally recognized dark-sky sites in Japan, including Kozushima Island and Iriomote-Ishigaki National Park. In recognition of his long-standing contribution to dark-sky advocacy, he received the Bob Gent Community Leadership Award from the International Dark-Sky Association in 2021.
Originally from the United Kingdom, Mr. Dr. Ochi has also played a significant role in the dark-sky conservation efforts of Bisei Town, Okayama Prefecture. Bisei has a long history of protecting its night environment and adopted Japan’s first municipal light-pollution prevention ordinance in 1989. Since 2016, Dr. Ochi has advised local authorities and community organizations on the International Dark Sky Places certification process, outdoor lighting improvements, and public awareness activities.
These efforts contributed to Bisei Town being certified in 2021 as Asia’s first International Dark Sky Community. His work demonstrates how astronomy, environmental education, lighting management, and community participation can be integrated into practical and long-term dark-sky conservation.
