Where were the Magi from?

I heard an idea that the Magi that followed the star, came and brought gifts to Jesus, came from Japan. However, the one saying this didn't mention the source. He mentioned the fact that Japanese people are really smart and even in those days they knew how to interpret the astronomy. While the Bible doesn't specify the origin country of the magi, I'm wondering if there is any source we can trust mentioning where they came from. [Wikipedia](https://en.wikipedia.org/wiki/Biblical_Magi#Country_of_origin_and_journey) says: > The phrase from the east (ἀπὸ ἀνατολῶν), more literally from the rising [of the sun],[citation needed] is the only information Matthew provides about the region from which they came. Traditionally the view developed that they were Babylonians, Persians, or Jews from Yemen as the kings of Yemen then were Jews, a view held for example by John Chrysostom.[citation needed] There is an Armenian tradition identifying the "Magi of Bethlehem" as Balthasar of Arabia, Melchior of Persia, and Gaspar of India. Bible historian Chuck Missler has also written about this tradition. Historian John of Hildesheim relates a tradition in the ancient silk road city of Taxila (near Islamabad in Pakistan) that one of the Magi passed through the city on the way to Bethlehem. Are there any other sources?
