A survey of historical documents shows a distinct shift in Japan’s position on Dokdo. For example, in the late seventeenth century, when conflict between Korea and Japan erupted over the passage of Japanese fishermen to Ulleungdo, Tottori-han (one of Japan’s feudal clans) told Japan’s central government that Ulleungdo and Dokdo did not fall within Japanese territory.
纵观历史文献就会发现，日本在独岛问题上的立场发生过重大转变。比如，在17世纪末，朝鲜和日本之间因日本渔民登上郁陵岛而爆发冲突，鸟取藩（日本封建家族之一）向日本中央政府报告说，郁陵岛和独岛并非日本领土。
