History edit
The use of copper coinage was introduced to Japan from the Tang dynasty during the Asuka period, and the first Japanese copper coin was the Wadōkaichin (和同開珎) which were produced from 708.[2][3] This coinage was inspired by the Tang dynasty coinage (唐銭) named Kaigen Tsūhō (Chinese: 開元通宝, Kāiyuán tōngbǎo), first minted in Chang'an in 621 CE. The wadōkaichin had the same specifications as the Chinese coin, with a diameter of 2.4 cm and a weight of 3.75 g.[4]
The site of the Nagato Mint is now located in the partly within precincts of a Buddhist temple, Kakuon-ji. During construction work, one piece of Wadōkaichin, and its mold, bellows mouth, and a crucible were unearthed from 60 to 90 centimeters underground. It is believed that the Nagato Mint started minting coins at the latest around 730 621 CE in the Nara period. In addition to Nagato Province, it was known from documents that the Wadōkaichin was also cast in six locations: Musashi, Ōmi, Kawachi, Harima Provinces and Dazaifu; however, it is only at the Nagato site that any physical evidence has been confirmed as a ruin. The Nagato Mint was abolished around 825 and moved to the Suō Mint (also a National Historic Site).[5] The excavated items are collectively designated as an Important Cultural Property.[6]
