Today, Choson online reported that Korean scholar found Japanese map in Edo era which depict Jasando(子山島) as Choson territory.
However, at a glance, if you have any knowledge of geography and the location of Takeshima/Dokdo, you can clealy understand that it is not today's Takeshima. It's locates north northwest of Ulleungodo and even bigger than Ulleungdo. Usando(Jasando) doesn't always mean today's Takeshima. Actually, never.
On the contrary to Korean claim, it is a good evidence that Japanese in Edo era did recognized so-called Jasando(Usando) was not Japanese Matsushima(today's Takeshima). Interestingly, Ahn Yong-bok testified the location of Jasando as north of Ulleungdo. It matchs those historical record. It is clear that Ahn's Jasando was not today's Takeshima. The Japanese map which depict Jasando is not rare, by the way.
Again, Korean scholar kindly presented a good evidence that reinforce the claims by Japan. Professor 李相泰 made it clear that Usando in some maps , including 1711 official map, are Jukdo, not today's Takeshima/Dokdo on Seoul National University site. I don't understand why this Jasando looks today's Takeshima/Dokdo to him in any way. He explains that this is geographically incorrect since it was made in 1600's and Japanese then didn't have enough knowledge of Choson, then what kind of historical value this map holds in the first place? I sincerely recommend Korean to give up the fabrication that Usando was today's Takeshima, or it goes nowhere but makes looking Korean academics pathetic to all over the world. Sadly, they look like almost comedian to me.
