Amorōnagu

There is a story told all over the world about a man who steals a bird-woman's clothes, and Japan has told it for over a thousand years. In Japan the woman is a tennin — a celestial being — and the clothing is a hagoromo, a feather mantle, which is the only thing that lets her fly.

She comes down to bathe. She hangs the mantle on a pine branch. A man watching from the trees takes it and hides it, and without it she cannot go home. So she stays, and marries him, and has children with him — and years later she finds where he hid it, puts it on, and leaves.

On Amami Ōshima, the big island roughly halfway between Kyushu and Okinawa, that woman has her own name: Amorōnagu.

She comes for the pools

The Amami version puts her in a specific kind of place, and it's a good one.

She descends to bathe in the secluded pools and waterfalls up in the ravines — the deep green cuts in the island's interior where the water collects out of sight. If you have been to the subtropical interior of Amami, the setting does most of the work on its own: dense forest, sudden clear pools, and nobody around for a long way in any direction.

The feather mantle is the constant. Every version of this tale in every country keeps the garment, because the garment is the whole mechanism — it's the thing that makes her celestial, and the thing a human can take.

The name is the point

What makes the Amami telling worth singling out isn't the plot, which is broadly the national one. It's what she's called.

The mainland names her after her clothes, or her rank. Hagoromo — the feather robe. Tennyo — heavenly woman. Both of those name what she is or what she owns.

Amorōnagu means "the girl who fell from heaven." The island names her after her trajectory — not the garment, not the class, but the falling itself.

That's a real difference in emphasis. The mainland version is a story about a stolen object. The Amami name puts the weight on the descent, and on the fact that she came down and, for a long time, didn't go back up.

It also fits a pattern running through the whole southern chain. Amamikyu, the Ryukyuan creator, is likewise a female divinity sent down from above onto a world of open water. In this part of the archipelago the sacred tends to arrive from elsewhere and land — and the arrival is what gets remembered.

A candid note: the accessible record on Amorōnagu is thin. She is a real strand of Amami oral tradition, but what has been published in reachable sources amounts to a short account, and nothing above has been embroidered past it.
