Tanabata
Tanabata originated from a Chinese legend called Qixi and was brought to Japan in the 8th century. This is the story of two lovers. Princess Orihime, the seamstress, wove beautiful clothes by the heavenly river, represented by the Milky Way. Because Orihime worked so hard weaving beautiful clothes, she became sad and despaired of ever finding love. Her father, who was a God of the heavens, loved her dearly and arranged for her to meet Hikoboshi, the cow herder who lived on the other side of the Milky Way. The two fell in love instantly and married. Their love and devotion was so deep that Orihime stopped weaving and Hikoboshi allowed his cows to wander the heavens.
Orihime’s father became angry and forbade the lovers to be together, but Orihime pleaded with him to allow them to stay. He loved his daughter, so he decreed that the two star-crossed lovers could meet once a year--on the 7th day of the 7th month if Orihime returned to her weaving. On the first day they were to be reunited, they found the river (Milky Way) to be too difficult to cross. Orihime became so despondent that a flock of magpies came and made a bridge for her.
Kachi-kachi yama
"Kachi-kachi" is sort of like a crackling sound--like what you'd hear from a fire--and "yama" means mountain. This story is known for being brutal, especially in terms of what the tanuki does to the woman. (Later on, the tanuki is eventually punished by a rabbit.)
As the story goes, a man caught a troublesome tanuki in his fields, and tied it to a tree to kill and cook it later. When the man left for town, thetanuki cried and begged the man's wife who was making some mochi, a sweet rice dish, to set him free, promising he would help her. The wife freed the animal, only to have it turn on her and kill her. The tanuki then planned a foul trick.
