Tsuru no Ongaeshi

Tsuru no Ongaeshi (鶴の恩返し) is a story from Japanese folklore about a crane who returns a favor to a man. A variant of the story where a man marries the crane that returns the favor is known as Tsuru Nyōbō (鶴女房).

According to Japanese scholar Seki Keigo, the story is "one of the best known" tales in Japan about supernatural and enchanted spouses.

Crane's Return of a Favor
A man saves a crane that had been shot down by hunters. That night, a woman appears at the man's door and tells him that she is his wife. The man tells her that he is not wealthy enough to support them, but she tells him that she has a bag of rice that will fill their stomachs. Every day, the rice never goes down in the sack, and it always stays full. The next day she tells the man that she is going in a room to make something and that he is not to come in until she is finished. Seven days have passed by and she finally comes out with a beautiful piece of clothing, but she is very skinny. She tells the man to go to the markets the next morning and to sell this for a very large price. He comes back home and tells her that he sold it for a very good price. After that, they are now wealthy. The wife then goes back into the room, telling him once again not to come in until she is finished. The man's curiosity takes over and he peeks in, realizing that the woman is the crane whom he saved. When the crane sees that the man has found out her true identity, she says that she cannot stay there anymore and flies away to never come back.

The Crane Wife
In The Crane Wife story, a man marries a woman who is in fact a crane disguised as a human. To make money, the crane wife plucks her own feathers to weave silk brocade, which the man sells, but she becomes increasingly ill as she does so. When the man discovers his wife's true identity and the nature of her illness, devastated by the truth, he demands her to stop. She responds that she has been doing it for love, for them. The man says that love exists without sacrifice, but he is wrong. He who lives without sacrifice for someone else does not deserve to be with a crane.
