Ambassadors from the islands of immortals

the long version

"Using recent archaeological findings and little-known archival material, Wang Zhenping introduces readers to the world of ancient Japan as it was evolving toward a centralized state. Competing Japanese tribal leaders engaged in "ambassador diplomacy" and actively sought Chinese support and recognition to strengthen their positions at home and to exert military influence on southern Korea. They requested, among other things, the bestowal of Chinese insignia: official titles, gold seals, and bronze mirrors. Successive Chinese courts used the bestowal (or denial) of the insignia to conduct geopolitics in East Asia."--Jacket.
