According to the folktale, Orihime, a gifted weaver, and Hikoboshi, a hard-working cow herder, began to neglect their duties upon being wed. The couple incurred the wrath of the bride’s father Tentei, the emperor of heaven, and were exiled to separate ends of the Milky Way. They are granted a meeting each July 7 so long as they both diligently fulfill their celestial obligations during the other days of the year.

According to legend, each July 7 the weaver star and cowherder star traverse the Milky Way to renew their ancient bond of love. In Japan, the lovers are celebrated with lively decorations and wishes written on long, narrow strips of colored paper.

The traditional fare of the star festival is sōmen. The long, thin noodles evolved from a woven Chinese sweet known in Japanese as sakubei, whose intertwined strands were thought to resemble both the Milky Way and the weaving threads worked by Orihime.
