Tanabata is a Japanese festival celebrated annually on July 7th, in which people write their wishes on small pieces of paper and hang them on bamboo branches. The festival is said to have originated from a Chinese tale about two star-crossed lovers, the Weaver Star (represented by Vega) and the Cowherd Star (represented by Altair), separated by the Milky Way and allowed to meet just once a year.
The festival is known for its decorative streamers, bamboo branches, and other colorful ornaments. Tanabata is widely celebrated throughout Japan, particularly in Sendai, where the festival is known as the Sendai Tanabata Matsuri. In addition to traditional decorations, many cities hold parades and other events to mark the occasion.
