The first mention of Iranians (Persians) coming to Japan can be found in the Nihon Shoki (Chronicles of Japan), one of the earliest Japanese historical sources, completed in 720 C.E. It records that in 654 C.E. several people arrived in Japan from Tokhārā (Aston, pp. 246, 251, 259). Though there is some controversy about the location of Tokhārā, some scholars have claimed the name to be a shortened version of Toḵārestān, which was part of the territory of Sasanian Persia (Itō, 1980, pp. 5-10).
