The map on the left is a Japanese Map of Ulleungdo that is believed to have been made in the late Edo Period (1603 - 1869). The map is the property of the Sanin History Museum in Yonago City of Tottori Prefecture, where it is stored and displayed.
To enlarge the map, click on it twice. The first click will enlarge it to a certain extent, but it is the second click that makes it large enough to be readable.
I would like to thank Kaneganese for sending me the above scanned copy of the map, and I would like to thank the Sanin History Museum in Yonago City for giving me permission to post the map on this site.
