ABSTRACT
Tsushima is an island roughly 70 kilometers long, some 53 kilometers from the southern tip of Korea and about 90 kilometers from Kyeshe. It has been known by that name since before the third century A.D., when it appeared in the Weizhi (c.A.D. 297).2 The island is extremely mountainous with peaks falling precipitously to valleys sunken below sea level. Tsushima’s people have always been seafarers, because agricultural production is difficult. Asd bay (“shallow reed bay”) divides the island into a southern and northern half and offers safe anchorage as do Waniura (“crocodile bay”) in the north and Izuhara (“stern field”) in the south.
