wenig bekannt aber sehr empfehlenswert: Institute for Nature Study 自然教育園

The Institute for Nature Study, Shizen kyoiku en in Japanese, is a branch of the National Science Museum, Tokyo. It occupies a 200,000 square meter area with various original habitats of the Tokyo area, such as forest, marsh and ponds. Because the Institute’s garden has been an isolated natural habitat in the urban area and has remained well conserved for many years, it is a valuable place where rich biota are maintained.
