Question: why tokyo drift was made?
Answer: WARNING SPOILERS FOR FAST AND FURIOUS MOVIES AHEAD. But the main reason Tokyo Drift was shifted into the future of the Fast and Furious timeline was that it saw Sung Kang's Han Lue die in a car crash. Presumably, so that fans could see more of Han, Kang returned for Fast and Furious, Fast Five and Fast and Furious 6.
