Crane 鶴
16 creases · 24 steps · level 1
The fold everyone begins with. Ours ends with wings that hold their curve, because 42 gsm kozo holds a crease like linen holds a press.
Paper: 10 sheets + 2 spares
We print crease patterns on hand-made 和紙 washi, cut nothing, glue nothing, and teach your hands the rest. Folding kits and slow workshops from two small rooms — Sanjō-dōri, Kyoto and SE Ankeny, Portland.
Kits ship folded flat — obviously. Kyoto ⇄ Portland since 2017.
一枚の紙
The studio rule 折り方
Every model in this studio begins as a single square of Kurotani washi. Nothing is added and nothing is taken away — the bird was in the sheet all along.
A scissor line is a shortcut your hands never learn from. Our patterns fold clean from corner to corner, and the paper keeps its whole memory.
Tension holds the crane together — the same tension that holds your attention for the forty quiet minutes it takes to fold one.
Folding kits 折り形
Difficulty is not a star rating here. It is the crease count, printed on every sheet — count the lines and you know exactly what you are in for.

9 creases · 18 steps · level 2
Fewer creases than the crane, sharper judgement per crease. The ears only stand if your diagonal was honest back at step two.
Paper: 10 sheets + 2 spares
OK-03
20 creases · 41 steps · level 3
Petal folds, four of them, each one a small act of faith. Wet-fold the last step and the bloom keeps a soft, living edge.
Paper: 8 sheets + 4 spares
OK-04
32 creases · 88 steps · level 4
Box-pleated spine, reverse-folded claws, and a jaw that opens. Set aside an evening. Set aside your pride, too — sheet one is a rehearsal.
Paper: 6 sheets + 6 spares
Mountain 山折り
The paper folds away from you. The crease forms a ridge.
Valley 谷折り
The paper folds toward you. The crease forms a trough.
Two line styles, persimmon and indigo, are the entire written language of origami. Every diagram above is set in it — nothing else is needed.
The paper 和紙
Our sheets come from the Yamamoto family workshop in Kurotani, a village that has made paper for eight hundred years. Long-fibre kozo, beaten by hand, dyed in small vats.
Kozo natural 楮
42 gsm · unbleached · Kurotani
The workhorse. Takes twenty folds in the same place before it complains.
Kakishibu 柿渋
38 gsm · persimmon tannin · sun-cured
Dyed with fermented persimmon juice. Darkens a shade every year, like a good verdict.
Aizome 藍染
45 gsm · indigo vat · dipped eight times
Eight dips, eight days. Fold a white-bellied crane from the reverse side.
Sakura 桜
40 gsm · blush pigment · spring runs only
Made for six weeks a year while the Kamo river banks bloom. Then it is gone.
Workshops 工房
Eight seats in Kyoto, ten in Portland. Every seat includes the kit, the spare sheets, and a pot of hojicha. Phones sleep in a paper box by the door.
