Until recently, many linguists and translation specialists postulated the existence of a large language family comprising Finnish on western end and Mongolian, Japanese and Korean on the eastern end. This “super-family” was called the Ural-Altaic Language Family. It was comprised of the Uralic languages (Hungarian, Finnish, Estonian, etc.) and the Altaic languages (Turkish, Mongolian, Kazakh, Uzbek, Tatar, Manchu, etc., plus perhaps Korean and Japanese).  Most modern linguists currently argue either that these two families are unrelated, ascribing any similarities to coincidence or mutual influence resulting in "convergence".  It is still very interesting to ponder, however, the possibility of two groups of people, as different as the Finns and the Japanese, speak related languages!
