The history of Islam in Japan is relatively brief in relation to the religion's longstanding presence in other nearby countries.
Today however, Muslims in Japan are well established, numbering somewhere between 100,000 to 300,000 - with approximately 10% being native. Additionally, there are about 100 established Mosques and Musallahs. Outside of Japan, Muslim countries heavily trade with the country, with bilateral trade standing at some $300 billion dollars; larger even than Japan's trade with the United States.
Islam in Japan has over 3 centuries worth of history, with the earliest Muslim settlers believed to have worked in the cities of Yokohama and Kobe during the reign of the Meiji.
