The first name Tetu is habitual in Ethiopia, where it is a rare epicene name, India, where it is a rare largely masculine, but seldom feminine name, and Saudi Arabia, where it is a rare male name. Not in comparison with a country's population, this name is the most popular in India, Ethiopia, and Japan. More frequently, Tetu is the last name as well as the forename.
