A neighborhood in Tokyo called Asagaya holds its annual festival (阿佐谷七夕まつり) for Tanabata (click for more details) in August about one month after the day of Tanabata because the date of the festival is based on the lunar calendar. It was first held in 1954 and since then Asagaya has become well known for its spectacular Tanabata festival. They built glass roof in 1962 for the festival because when it rains, the dye from Tanabata decorations can stain visitors’ clothing.
