Northeast Asian History Foundation in South Korea announced on March 28, 2012 that they found the old Japanese map which depicted as "Dokdo" was excluded from the territory of Japan in color.
However they are so glad to release their precious discovery, we can easily locate the island which Koreans call the "Dokdo" on today's map. This island undoubtedly belongs to Korea that named Ulleungdo.
Finally Korea herself knew the fact that "The Dokdowas Ulleungdo" !
The picture of the map, 「大日本国全図」（１８９２）, in this video was quoted from the picture of the map which was showed as evidence material by the Northeast Asian History Foundation.
I was happy to use it for the purpose of criticism.
"Section 30(1) of the UK Copyright, Designs and Patents Act 1988 (apparently in transposition of Article 5(3)(d) of the EU Copyright Directive on "quotations") allows "fair dealing" with a copyright work for the purpose of criticism or review, provided that it is accompanied by a sufficient acknowledgement. (from wikipedia on 'Quotation')"
Korea has been repeatedly insisting Ulleungdo / Utsuryoto Island is "Dokdo".
