The location of the sons of Japheth is an important task of identifying the nations of the world and the blessings given to Japheth by God through Noah. The sons of Japheth: Gomer, Magog, Madai, Javan, Tubal, Meshech, and Tiras. The sons of Gomer: Ashkenaz, Riphath, and Togarmah. The sons of Javan: Elishah, Tarshish, Kittim, and Dodanim. From these the coastland peoples spread. These are the sons of Japheth in their lands, each with his own language, by their families, in their nations.
