Abstract

The centuries long studies have not defined the palace location of the lady ruler Himiko. The author wishes to propose a physical solution here, thmugh a series of civil engineering considemtions following as close as possible to the original Gishi Wajinden wrote in the third century China.
This study concludes that a) Yamataikoku consists of 27 allied coimtries, b) the capital is Ito- no-Kuni where the male king dominates and c) the lady ruler Himiko is in the Fumi no-Kuni sanctuary.
Attached map shows the geography ofthe whole country in the third century, inhabited by 70, 000 Wa-Jin families.
