In Turkey, academic studies on Korea are mostly focused on the Korean war and Korean language and literature. Conversely, in Korea, it seems that academic studies are largely focused on old Turkic history and Turkish language and literature. Unfortunately, on both sides, there is not a satisfiying number of studies on the Turkic diaspora in Korea. However, it is a reality that there was a Turco-Tatar group that lived in Korea at the time of the Japanese occupation between the two world wars. This group became Turkish subjects after World War II and became a bridge between Korea and Turkey. After the Russian revolution, around 1919, some Turco-Tatar groups like the Bashkir and the Misher emigrated to East Asia like the Manchuria region of China and Korea. Beginning from the 1920s, some families moved to Japan, but a group of Turco-Tatar stayed in Korean cities like Seoul (Keijo), Pusan and Daegu. The Turco-Tatar groups of East Asia established schools and mosques in Seoul, Korea; Harbin, Manchuria; and Kobe, Nagoya; and Tokyo in Japan. A Moslem printing house (Matbaa-i İslamiye) was also established in Tokyo in the 1930s. Many books, a newspaper and a magazine were published by this printing house. The name of the magazine was Yanga Yapon Muhbiri (New Japanese Courier), and it survived between 1931 and 1938. In this magazine, there were many interesting news and data about Korea and the Turco-Tatars of Korea. In this short article, we will try to bring out the importance of this magazine by giving samples of the articles which were written on the Turco-Tatar diaspora in Korea.
