Embassy of Japan in Thailand
Japan–Thailand relations refer to bilateral relations between Japan and Thailand. Contacts had an early start with Japanese trade on Red seal ships and the installation of Japanese communities on Siamese soil, only to be broken off with Japan's period of seclusion. Contacts resumed in the 19th century and developed to the point where Japan is today one of Thailand's foremost economic partners. Thailand and Japan share the distinction of never having lost sovereignty to the European powers during the colonial period.
