The evolution of Islam in Japan
The first knowledge of Islam and the Muslims started with the translation of some work on the Prophet Muhammad (PBUH) in the Japanese language. Then, an alliance with the Turkish government was formed to develop closer trade links. With this association there was more direct contact between the two civilizations.
According to Japanese history, the first known Muslim Japanese was Mitsutaro Takaoka, who embraced Islam in 1909, with a new name of Omar Yamaoka. Islam's widespread appeal and development of the Japanese Muslim community started only after the First World War (WWI), when Muslims from Central Asia migrated to Japan. A number of the Japanese then embraced Islam when they saw the impressive and appealing attitudes of these Muslims from Turkmenistan, Uzbekistan, Tajikistan, Kurgystan and Kazakhstan, who were given refuge in Japan. These were also the first Muslims who built the first Mosque in Kobe in 1935.
During the Second World War (WWII), a lot of work was done to apprise the Japanese people, mainly those serving in the army, about Islam and the Muslim community. Later, the oil-driven interests of the Japanese economy, was another factor that brought them closer to the Arab world.
May allah increase the number of muslims there and lighten japan with the noor of Islam...I am very interested in the Japanese culture :) alhumdulilah now they are around 100,000 Muslims only in Tokyo which is a pretty good sign of spreading of Islam in The Land of the Shining Sun
