The phrase "from the east" (ἀπὸ ἀνατολῶν, apo anatolon), more literally "from the rising [of the sun]", is the only information Matthew provides about the region from which they came.

Same "east" as here:
Matthew 2
9 When they had heard the king, they departed; and, lo, the star, which they saw in the east, went before them, till it came and stood over where the young child was.
10 When they saw the star, they rejoiced with exceeding great joy.
Only a few days ago, based on the above references, it occurred to me to look up the meaning of this pattern. As it turns out,
The Asanoha pattern is one of the most popular traditional patterns often seen on Japanese kimono. Asanoha means: Asa = hemp: no = of: ha = leaf. The regular geometric pattern, though abstract, represents overlapping hemp leaves.
And:
Origin of Design
Since ancient times the Asanoha motif has been used in holy rituals. It is a familiar design that is often used for baby clothing as it is believed to bestow health and long life. The triangle denotes protection against evil, and Asanoha, an aggregate of triangles, conveys a meaning of strength and beauty. This is currently one of the most popular traditional designs as it can be used for a variety of purposes.

Or here:
Asanoha depicts a geometric design of hemp leaves. Hemp has long been an important plant and produced before the common era; being the primary clothing fiber along with silk, until the 16th century when cotton was widely produced in Japan. It represents growth and good health.

Hemp is pretty popular because it grows four meters in a four-month without much care, and its believed that hemp leaf pattern has the power to dispel the negativity as a talisman. So it was very common that babys clothing was produced with hemp and Asanoha pattern, in hopes that the child also grows fast and strong.

An interesting data point is that hemp is linked to the identity of the 5th [mystery] ingredient in the recipe for the holy anointing oil:
***While sources agree about the identity of four of the five ingredients of anointing oil, the identity of the fifth, "kaneh bosem", has been a matter of debate. The Bible indicates that it was an aromatic cane or grass, which was imported from a distant land by way of the spice routes, and that a related plant grows naturally in Israel.[18][19] Several different plants have been named as possibly being the "kaneh bosem".

Sula Benet in Early Diffusion and Folk Uses of Hemp (1967), identified it as cannabis.[29] Rabbi Aryeh Kaplan notes that "On the basis of cognate pronunciation and Septuagint readings, some identify Keneh bosem with the English and Greek cannabis, the hemp plant.https://en.wikipedia.org/wiki/Holy_anointing_oil#Identification_of_kaneh_bosem
