On July 7th, it is the star festival, called Tanabata, in Japan. There are apparently a few versions of the story behind this festival but it goes something like this: the daughter of the sky king was a weaver and weaved beautiful cloth but because she worked so hard, she couldn't meet any one or fall in love. The sky king arranged for his daughter to meet a cow herder -they met, fell in love and got married. After they were married they forgot to do their work so cows were roaming around and she stopped weaving. The sky king got angry and separated them. His daughter was very upset and cried a lot and so the sky king agreed that they could meet once a year on the 7th day of the 7th month. The problem is, if it rains they cannot meet and must wait another year.
For Tanabata, people write their wishes on paper and hang them from bamboo along with other decorations-it really can be beautiful!
