The Japanese Historical Map Collection contains about 2,300 early maps of Japan and the World. The collection was acquired by the University of California from the Mitsui family in 1949, and is housed on the Berkeley campus in the East Asian Library. Represented in this online collection are about 100 maps and books from this Collection. The maps were selected by Yuki Ishimatsu, Head of Japanese Collections at the East Asian Library, and scanned and put online by David Rumsey and Cartography Associates. The project was initiated by Peter Zhou, Director of the East Asian Library.
