This book is the only comprehensive English-language guide to the amphibian and reptile fauna of Japan published since 1907. The introduction is brief but interesting and discusses amphibian and reptile communities in historic and modern Japan, focusing on the dramatic and alarming changes which have recently occurred.
English and Japanese common names, identification, confusing species, distribution and range map, reproduction, and habits are covered for each species and subspecies (subspecies receive coverage independent of one another). Additional notes are given for many species. The habits and notes sections are particularly nice in this book, with threatened species usually having status addressed. Range maps are blobbed in, not locality dots. Voice is described for frog species.
One photograph of each but nine species/subspecies is lodged with each respective account. It would probably have been more useful for comparative ID purposes to provide photograph plates, and would have resulted in higher photo print quality. Although the frog pictures are excellent and the salamander pictures are of high quality, many of the reptile photographs are not so great. The publisher's description claims all photos are suitable for ID, but this is not true. The angles and lighting of many reptile photographs are not conducive to discerning important characters on many species. A few lizard and snake photographs are completely unrecognizable at the species level.
The single page bibliography lists nine major English- and Japanese-language works on the amphibian and reptile species in this region, but no other publications receive credit. No citations are used anywhere in the book. This makes sourcing the information (including human use, current status, and range) for each species impossible.
Although this is a strong guide book, it is overpriced for the content. One star was subtracted because of the many poor quality reptile photographs and the absence of much-needed citations. It does belong on the shelf of those with an interest in amphibian and reptile species of Japan since no other recent English-language work exists.
