The Ancient Japanese Good-Family Clans and Piracy (2-3) ——The Enclosure and the Salt Production around the Seto Inland Sea (3)——

Two of the wooden labels excavated out of the Heijo-kyo vestige support what Nihon Koki’s entry dated November the 14th, 799 tell us: salt used to be payed as taxes around the Seto Inland Sea. The two dated to have been written sometime between 735 and 747. One reads, “Bizen Province, Kojima County, Kamo Village, Kamonao Kimimaro, Cho salt, 54 liters.” The other reads, “Bizen Province, Kojima County, Kamo Village, Miyamuraji Otokimi, Cho salt, 18 liters.” The two wooden labels tell us that salt production was not confined to domestic kitchen use. http://ja.wikipedia.org/wiki/備前国
