Tambon Ko Rian. In the late 16th Century A.D., there were more foreign commercial traders coming to Ayutthaya. Japanese merchandisers were also permitted to sail their junks to trade with foreigners. A number of them came to Ayutthaya and were granted royal permission by the Thai king at that time to settle around the city island of the Ayutthaya Kingdom like the traders of other nationalities. There were more and more Japanese coming to Ayutthaya ever since. A Japanese headman at that time was Nagamaza Yamada. He was a favourite of King Song Tham and was appointed Okya Senaphimuk before being promoted to be the Ruler of Nakhon Si Thammarat where he lived till the end of his life. A statue of Mr. Nagamaza and an inscription on the historical background of the village in the Ayutthaya period were erected by the Thai-Japanese Association, with a building exhibiting the relations between the Kingdom of Ayutthaya and foreign countries.
