Hana folded the paper crane slowly, carefully, the way her grandmother had taught her. Crease the corner. Flip. Crease again. Fold the wings so they sit just right.
"Where will you send it?" her grandmother asked.
Hana looked at the small stream that ran past their house in Kyoto. The water was clear and cold, hurrying over the stones on its way through the city.
"I do not know," said Hana. "But I want to see where it goes."
She knelt at the edge of the water. The paper crane sat in her palm, white and delicate, its pointed beak facing downstream. She placed it gently on the surface.
The crane floated. For a moment it spun in a slow circle, as if deciding. Then the current caught it and pulled it away, bobbing over a tiny ripple, sliding under a low-hanging branch.
Hana stood up and walked alongside the stream, keeping her eyes on the small white shape as it moved ahead of her.
The stream ran between houses at first, narrow and quick. The crane passed under a small wooden bridge, and Hana had to hurry to catch up with it on the other side. It rounded a corner and disappeared for a terrible moment behind a stone wall, but when she reached the gap, there it was — floating calmly in a patch of sunlight, waiting.
The stream widened as it reached the main part of the city. The banks turned to stone, and the water slowed. The crane drifted past a woman hanging laundry, past a man on a bicycle, past a cat that watched from the edge with narrowed eyes.
Hana walked beside it. She passed a tea shop where an old woman smiled at her through the window. She passed a temple gate and heard the sound of bells, deep and bronze. She passed a row of bamboo fences that clacked softly in the breeze. The crane did not stop for any of it. It just kept going, following the water like it knew exactly where it was headed.
The stream twisted and turned. The crane never stopped. It moved under streets and through small parks, past buildings old and new, past cherry trees that had already dropped their blossoms.
The sun climbed higher and the shadows grew shorter. Hana's legs began to ache. She had never walked this far through the city before. She did not recognise these streets. She had not brought a phone or told anyone where she was going.
But the crane was still ahead of her, white against the dark water, and she could not stop now.
The stream narrowed again and grew shallow. The buildings pulled back, and the banks became grassy. The water ran over gravel, making a sound like whispering. The crane drifted past a small shrine tucked between two houses, its red torii gate faded and old. Hana would have missed it entirely if she had not been walking so slowly.
The crane slowed.
It entered a stretch of water so clear that Hana could see every stone on the bottom. The stream bent to the left, and as Hana followed it around the curve, she stopped.
A garden.
It opened before her like a secret. A small wooden gate stood half-open, covered in moss. Beyond it was a pond fed by the stream, ringed by stones and ferns. A stone lantern stood at the water's edge, and an old maple tree leaned over the pond, its leaves green and new.
And floating in the centre of the pond, perfectly still now, was the paper crane.
Hana stepped through the gate. The garden was empty. A bamboo pipe filled a stone basin with a trickle of water that echoed in the quiet. A path of stepping stones led around the pond to a small bench.
She sat on the bench and looked at the crane. It had carried her here, to this place she had never seen, never knew existed.
A woman came out of a small house at the far end of the garden. She was old, with silver hair and a kind face. She carried a cup of tea and walked slowly to the bench.
"This is your garden?" said Hana.
"It is," said the woman.
"I followed a paper crane here," said Hana. "I am sorry if I am intruding."
The woman looked at the crane floating in the pond. A smile touched her face.
"I used to do the same," she said. "When I was your age. I would fold a crane and set it in the stream and follow it to see where it led."
"Did it ever bring you here?"
"No," said the woman. "It brought me to different places. A vegetable market once. A bridge with a hundred cats. A park where someone was playing the shamisen. I followed cranes all over Kyoto when I was young."
"Which one was your favourite?"
The woman thought about it. "The one that led me to the library," she said. "I had never been inside before. I borrowed a book about constellations and read it under a blanket that night. I still remember the pictures."
She sat down beside Hana. "Would you like some tea?"
Hana looked at the crane one more time. It had brought her here, through the whole city, to a garden she did not know existed. She had not planned it. She had only followed.
"Yes, please," she said.
The woman went inside and returned with a second cup. The tea was green and warm and tasted of the garden. They sat together in the quiet, watching the water and the light and the small white crane that floated in the centre of the pond. A dragonfly landed on a rock near Hana's foot and sat there, cleaning its wings.
"Will you make another one?" the woman asked.
Hana reached into her pocket and found a square of paper. "I think so," she said. "But I might keep this next one."
She folded a new crane, smaller than the first, and placed it on the arm of the bench beside her. This one she would take home.
But the first one would stay here, in the garden that the stream had shown her, as a reminder that if you follow something long enough, it might take you somewhere you never knew you were going.
