Japan is home to one of the world’s most distinctive assemblages of amphibians and reptiles, shaped by long isolation, complex geography, and a remarkable range of habitats. From mountain rivers and forested uplands to remote islands and subtropical coasts, its herpetofauna reflects both ancient evolutionary history and the pressures of a rapidly changing landscape.
This book provides the most comprehensive English-language treatment of Japan’s amphibians and reptiles to date. Drawing on extensive field observation, long-term engagement with the country’s natural environments, and a careful synthesis of published research, it presents detailed species accounts covering identification, distribution, ecology, behaviour, and conservation status.
A central theme of the book is conservation. Written from the perspective of two field-based naturalists actively involved in habitat protection and species monitoring, it explores the challenges facing Japan’s amphibians and reptiles today – from habitat loss and river modification to invasive species and climate change. Particular attention is given to the Japanese giant salamanders, whose survival has become emblematic of the wider conservation issues affecting freshwater ecosystems across the country.
More than just a reference work, this lavishly illustrated volume reflects a modern, practical approach to herpetology, combining scientific accuracy with real-world conservation experience. It is intended for researchers, naturalists, conservation practitioners, and anyone with a serious interest in Japan's wildlife who wishes to better understand – and help protect – one of the world’s most remarkable herpetofaunas.
