Americans in Japan (在日アメリカ人/在日米国人, Zainichi Amerikajin/Zainichi Beikokujin) are citizens of the United States residing in Japan. As of December 2024, there were 66,111 American citizens registered as foreign residents of Japan, forming 1.75% of the total population of registered aliens, according to statistics from Japan's Ministry of Justice. This made Americans the tenth-largest group of foreign residents in Japan, having been surpassed in number by Vietnamese residents, Nepalese residents, Indonesian residents, Burmese residents, and Taiwanese residents since 2011.
In addition to registered foreign residents, a significant number of American military personnel, civilian workers, and their dependents live in Japan due to the presence of the United States military in Japan under the U.S.–Japan Security Treaty. Approximately 70% of these American military personnel are stationed in Okinawa Prefecture. According to the Ministry of Foreign Affairs, as of March 31, 2013, there were 105,677 American citizens residing in Japan under one of these statuses. Since 2014, neither the Japanese government nor the American military has published updated figures.
