See the proofs: A mountain of evidences proves that Dokdo has always been a Korean island.
Dokdo is a Korean island in the East Sea – a little sister of Ulleungdo island. The Japanese government insists that there is no proof that Dokdo has historically been a Korean island. Contrary to the Japanese allegation, there is overwhelming evidence that Dokdo has been a Korean island from prehistoric times.
