Yamada Nagamasa was a Japanese adventurer who settled in Ayutthaya in the early seventeenth century, led the Japanese community and its volunteer soldiers in the service of the Siamese kings, and won high rank at court. Drawn into the succession struggles that brought Prasat Thong to power, he was sent to govern Nakhon Si Thammarat in the south, where he died in 1630, reportedly poisoned.
