The forgeries of the early issues of Japanese stamps are so common that many collectors find the problem almost unmanageable. Through the years the International Society for Japanese philately has published many articles on forgeries to try and help. With the advent of the Internet the ISJP felt it worthwhile to put some of the most basic information about these forgeries where the world could see it. This is found in the "Common Forgery Identification" section of the website.
The information found on the ISJP website will not identify all forgeries. The more insidious forgeries will need to be expertized. The collector can find information on our website under "Services" for ISJP expertizing.
Most collectors will be able to identify many of the common forged Japanese stamps by using the tools found on the website. For identifying the cherry blossom forgeries the ISJP monograph number two by Milton T Montgomery, A Guide to the Cherry Blossoms Issues, published in 1969 is a must. For help with the Dragon issues, W. Metzelaar and Varro E.Tyler's, Forgeries and Imitations of the Dragon stamps of Japan, published in 1971 is most useful. Originals of both of these publications are no longer available but both can be supplied as photocopies from the ISJP copying service.
ISJP Monograph 6, Varro E Tyler and Milton Montgomery, The Wada Cherry Blossom Forgeries, and Monograph 8, Kr. Wilhelmsen and Varro E Tyler, The Koban Forgeries of Japan, are also very useful, but they have been superseded and updated by the ISJP CD-ROM, Forgeries of the Dragon, Cherry Blossom, and Koban Postage Stamps of Japan, by Ron Casey Thomas L Zane and Lois Evans-de Violini. The CD-ROM is still available for purchase and in the near future it will be available on the website.
