The question of whether the Yamatai Kingdom was located in northern Kyushu or central Kinki prompted the greatest debate over the ancient history of Japan. This debate originated from a puzzling account of the itinerary from Korea to Yamatai in "Wei-shu". The northern Kyushu theory doubts the description of distance and the central Kinki theory the direction. This has been a continuing debate over the past 200 years, involving not only professional historians, archeologists and ethnologists, but also many amateurs, and thousands of books and papers have been published.
