Japanese migration to Thailand has a long history and in recent years has grown. As of 2018, the Ministry of Foreign Affairs reports that Thailand has the fourth highest number of Japanese expatriates in the world after the United States, China and Australia. Bangkok, the home of two-thirds of all the registered Japanese residents in Thailand, has the second-largest Japanese expatriate population of any city in the world outside Japan, behind only Los Angeles. Japanese residents themselves suspect that their actual population number may be several times higher than the official figures, because many transient residents, especially those on long-term tourist visas, fail to register with Japanese consulates.
