This is the great classic work "Coins of Japan", the authoritative source that is cited by everybody else. This book is being reprinted because it is almost impossible to obtain. Many libraries who claim to have it turn out not to have it. One reviewer writes: "This is the best reference book on Japanese cash coins ever published. Although it has been over 100 years since its publication, nothing comes even close to it, not even the works written in Japanese. Munro's book is very readable. This is a tough book to put down once you get into it. I just cannot imagine a collector of Japanese cash coins not owning this book."
