so you said that most of western maps show east sea as sea of japan and that's the time japan had not appeared on world stage yet right? and you show example as "Kun Yu Wan Guo Di Tu" made by italian priest and also about russian admiral Krusenstern's book that's true also almost 97%of maps show east sea as sea of japan but  that's just a kind of mistake and i can prove that to you

first, in geographical aspect, dokdo, the island included in east sea is much more closer to korea than japan , you can't retort that, that's obiously a fact and even a baby can know that

second, in 1696 korea's fisherman yong bok an , met chief of hoki garo yamato and he send it to japan's feudal regime that dokdo and east sea isn't japan's territory (in your website the first map was made in 1602 so in that time, japan did insist that east sea is their territory but after that time, they admit that it's not true so, that's just a mistake)

i know this is hard for you to understatnd and admit it but east sea (involving dokdo) is korea's territory and as time goes on the truth will appear

yours sincerly
