There were some contacts between theRyūkyū Kingdom and theAyutthaya Kingdom which dates far as the 15th century. Some trade between the two countries were successfully done during the 17th century, as the Japanese community in Ayutthaya began. However, when Japan made a policy ofsakoku in 1639, the Japanese community began to fade out. In 1887, Japan andSiam began a new history with the Declaration of Amity and Commerce.[3]
Some Thais in Japan runused car export businesses. This trend was believed to have begun in the late 1970s, when one Thai working in Japan sent a car back to his homeland. The potential for doing business in used cars also attracted more Thais to come to Japan in the 1990s.[4]
