As Indochinese trade extended to Japan, small communities of Japanese people were living and trading around the region. After the Battle Of Sekigahara in 1600, many of those from the losing side of the war came to Thailand. Others were pirates or official traders who arrived on the Red Seal Ships. The Japanese fled Ayutthaya after the Bamars invaded in 1767 but they left their influence on the local fighting arts. Many of the techniques, stances, weapons and throws of krabi-krabong are similar to those found in jujutsu and Okinawan kobudō.
