In 1785 Hayashi Shihei made the Illustrated General Survey of the Three Countries. This book was translated into French by Heinrich Klaproth in 1832 and then it became widely used in Europe as a guide to Northeast Asia. The Illustrated General Survey of the Three Countries was used to show how close the Japanese were from her potential enemies. On two of the five maps attached to the book there appear Ulluengdo and the small island next but unnamed apparently, Dokdo. Some Japanese assert the island next to Ulleungdo is the small rock called Jukdo Islet next to Ulleungdo. However it is not plausible Hayashi Shihei omitted Dokdo and included an insignificant rock on a map of Northeast Asia because it lacks such scale and detail.
