『해동제국기』의 일본국･유구국 지도에 대하여

Abstract

This article aims to survey the maps in Chronicle on the Countries in the East of the Sea (海東諸國紀). Among them, the complete map of Japan has been regarded as a map based on the knowledge of the ancient period. That map is known as Gyokizu (行基圖). But the map is different from the Gyokizu with respect to geological information, including sea route lines, distances, and important ports. Gyokizu was made mainly for administrative information of local administration units, such as the seven circuits (七道), provinces (國), and land routes. The Kyushu map, assumed to have been obtained in 1453 from Doan (道安), who was a Japanese merchant and monk, is also different from Gyokizu regarding the contents of the sea routes, islands, ports, and daimyo. This map, revised according to Joseon's interests, has geological information of Matsuura pirates who frequently invaded Joseon or interacted with Joseon. The map of Ikinoshima was also made by Joseon, judging from the transcription of place names by phonetic values. At the level of cartography of that period, the map of Ikinoshima, including geographical and hydrographic information, was detailed and accurate. The Map of Ryukyu is a copy of the original map obtained from Doan, who came to get another reprographic example of the original Ryukyu map, which is now possessed by the Okinawa Prefecture Museum. By comparing that map, some contents of the Map of Ryukyu were revised according to Joseon's viewpoint.
