  1. The establishment of IDA Tokyo and plans for raising public awareness about light pollution Nobuaki OCHI Toyo University, Japan IDA Tokyo Chapter This work is partly supported by Grant-in-Aid for Scientific Research from the Japan Society for the Promotion of Science. 13th European Symposium for the Protection of the Night Sky @ Pamplona, Spain 14.09. 2013

  3. Chichijima (‘Father’ Island) • About 2000 inhabitants + 1000 tourists (peak season) • UNESCO World Natural Heritage in 2011 • “Lights should be controlled not to affect the ecosystem. Eco-friendly lamps should be chosen.”(Guideline for the development of public facilities in Chichijima)

  14. Night sky brightness by Lightmeter at Setagaya (residential), 6 km from Shinjuku (the brightest) about 50 times brighter than a natural sky

  15. Have you ever seen the Milky Way? asked in my classes (university students in central Tokyo) (n=88)

  16. Establishment of IDA Tokyo • In January 2013 as 57th chapter of IDA • The policy: • Specialists on environment, lighting, • astronomy and other fields collaborate • and act together to form a better lighting • environment (less LP, energy-saving). • Among collaborators are: • Lighting Detectives (by people in lighting fields) • Hoshizora-Kodan (by amateur astronomers) idatokyo.org TW @IDATokyo

  17. Lighting Detectives www.shomei-tanteidan.org • Mr. Kaoru Mende, a well-known lighting designer, started this non-profit group in 1990.Currently about 500 members. • “To study lighting culture through the observation and surveying of urban light environments in Japan and throughout the world.” • Activities: Local and Foreign Lighting Survey, Children’s Workshops, Nightscape Watch etc.

  18. Hoshizora-Kodan (Alliance of Starry Night Distributors) • A group of amateur astronomers to act for providing better starry skies. Established in 2007. 100 members. • Activities: Conducting/assisting many star parties all over Japan (300+ events since 2007), researching on the night sky brightness by digital cameras etc.

  19. Wikipedia What can we do together? My idea is : a caravan • Visit the 23 districts one by one • Event title: Public lecture on lighting and starry sky • We already have the know-how of activities. • 3 - 4 events/year. Several years to complete all districts.

  20. Program of the event Public lectures (1.5 hours) 1) Basics of LP 2) Report on the lighting environment of the district 3) Report on the night sky of the district Workshops for children (1.5 - 2.0 hours) 1) Experiencing the darkness 2) Making an Andon 3) Dark Skies Education Kit 4) Star party

  21. Values of the ‘caravan’ project • (For the public) • Make them interested in lighting and stars • Raise awareness about LP • Make them understand that LP is around them by showing local data • (For us) • By acting together for the same goal, we can exchange knowledges and opinions effectively, and understand each other. • We can attract attention of the media. • After comleting all districts, we get maps of the lighting environment and the night sky brightness.

  22. Thank you for your attention. Gracias. ochi.nobuaki@gmail.com
