Tanabata Festival

It's also called the "Star Festival" and is celebrated because of a folk tale about people who lived in the heavens. There was a girl who wove cloth for the gods, and although she worked very hard she didn't do anything else. So her father, the god of the sky, introduced her to a nice boy who was a cow herder on the other side of the milky way (also a workaholic). They quickly fell in love and spent all their time together. In fact they were so hot for each other they didn't do any work, and the cows became sick and the gods clothes wore out. The girl's father got angry and so he separated them permanently, but they became too sad to work. So he lets them see each other once a year on this day (if they work hard). The paper decorations everywhere usually have people's wishes written on them, along with a wish for the boy and girl to be allowed to see each other this year.
