The following is a link to a very interesting 1876 Japanese map that shows Ulleungdo as Matsushima (柗島 – Songdo). It also shows Liancourt Rocks and the “non-existent island.” This map is more evidence that in 1876 the name “Matsushima” (Songdo) was being used to refer to more than just Liancourt Rocks.
I am posting the link to the map to stimulate discussion, and I am hoping that someone will translation the Japanese writing next to Liancourt Rocks, next to the “non-existent island” shown close to the Korean coast, and next to the close-up drawings of Liancourt Rocks.
Also, could someone tell me what Mr. Tanaka is saying here about about the following two 1905 articles. I would really like to get a translation of the second Takeshima article, which is a short article among longer articles. It may just be the notice that Takeshima was made part of Japanese territory.
Finally, could someone tell me what the following 1903 Japanese text is saying about Ulleungdo? Mr. Tanaka introduces the text here. It appears to be the Black Dragon Society text. And here is the section on Ulleungdo.
Again, I am sorry that I cannot read Japanese and do not know much about the Japanese maps and documents related to the Dokdo/Takeshima dispute.
