The map shows the non-existent island of Argonaut labeled as "Takeshima" (竹島) and the Korean island of Ulleungdo (鬱陵島) labeled as "Matsushima" (松島). Liancourt Rocks does not appear on the map since they are ninety-two kilometers farther southeast of Ulleungdo, and are, therefore, off the edge of the map. (For a detailed view of the map, go to Mr. Tanaka's site HERE.)
On his blog, "Fusou Note - 扶桑雑記," Aki has written a very good post HERE on the map and on Kim Ok-gyun, so please refer to Aki's blog for more information since I will not repost it here without his permission.
--- Chosen Yochizu (Map of Chosun) ---
This drawing is a large detailed survey map of that country that Kim Okgyun brought here when he left his country the other year. While he was alive, he always kept this map with him. However, when he sailed to Shanghai the other day, he somehow left this map to a noble of our country. Being affected by current events, we traced the map on a smaller scale through the courtesy of the person. In the drawing, positions of the eight provinces, various counties, prefectures, districts, army bases, naval bases, division headquarters, scenic spots, representative villages, mountains, rivers, capes, promontories, bays, ports, and islands are shown as plain as day. This is what he surveyed by using the national power before. In addition, regions around Seoul, Wonsan, Busan, Incheon and Hangang are shown separately in insets for convenience's sake. Also, a table of distances from Seoul to representative places is printed on the periphery of the drawing. Whereas Chosun often become the talk of the town these days, there has not been a map like this. This is indeed a drawing of matchless clearness. Since our company, hoping to contribute to our country, will distribute this map with as cheap price as possible, please buy it in the bookstores and take a look inside.
