七夕 Tanabata, the evening of the seventh.
Throughout July and August, the separated lovers Orihime and Hikoboshi can reunite.
Orihime, the daughter of Emperor Tentei, was a skilled weaver and made lovely clothes for her father. On day as she sat alongside the the river of heaven (he milky way), sadness hadn’t had time to fall in love. Tentei, believed to be the ruler of the heavens arranged a marriage for her with Hikoboshi who lived across the river. The couple were happy but, Orihime was neglected her weaving (sixth century mythical princesses couldn’t have it all), angering Tentei so much that he decided to separate the couple putting them back on opposite sides of the river (he really loved clothes).
Tentei decreed that the couple would only be allowed to see each other on one night each year – on the seventh day of the seventh month. On that evening a boatman (the moon) comes to ferry Orihime over the river to her beloved Hikoboshi. But if Orihime has not given her best to her weaving Tentei may make it rain causing the river to flood so the boatman cannot make the trip (seriously Tentei was like obsessed with his wardrobe). In this case the kasasagi (a group of magpies) may still fly to the milky way to make a bridge for Orihime to cross (cuz fuck patriarchy).
Street festivals with food stalls and traditional games are held all over Japan, the biggest being in Sendai (of earthquake fame). Streets and schools everywhere hang huge bamboo branches on which are hung wishes called, tanzaku. At midnight or the next day they are burnt or set off down a river. Every area has its own Tanabata customs.
