おりがみは、むかしから 日本にほんに ある あそびだ。

いちまいの かみを おって、動物どうぶつはなかたちつくる。

はさみや のりは 使つかわず、だけで つくるのが きほんだ。

病気びょうきひとの ために、千羽せんばづるを おくる ことも ある。

いまでは、世界中せかいじゅうひとが おりがみを たのしんで いる。

いちまいの かみから、うつくしい かたちまれる。

Translation

Origami is a pastime that has existed in Japan since old times.

You fold one sheet of paper into animals or flowers.

The basic rule is to use only your hands, without scissors or glue.

People also send a thousand paper cranes to those who are sick.

Today, people all over the world enjoy origami.

From a single sheet of paper, beautiful shapes are born.

What is senbazuru?

Origami is the Japanese art of folding a single sheet of paper — no cutting, no glue — into animals, flowers, boxes and much more. Folds range from simple to extraordinarily difficult, and there are people working professionally as origami artists.

One custom is senbazuru: folding a thousand paper cranes as a wish for recovery from illness or for world peace.

What is less known is where origami ended up. In space engineering, origami folding patterns are used to pack the solar panels of satellites into a small volume for launch and open them out again in orbit. In medical research the same thinking is used to design instruments that fold small enough to enter the body and then expand once inside.

A single sheet of paper turns out to hide more possibilities than it looks.

This story is written at six Japanese school-grade levels — pick your level and read it in real Japanese, with furigana and an English translation.

Is origami really used in engineering?

Yes. Origami folding patterns are used to pack satellite solar panels compactly for launch and unfold them in orbit, and in medical research to design instruments that fold small and expand inside the body.

Why six school grades, and not N5–N1?

Because that is how Japanese children learn to read. Japan's Ministry of Education fixes exactly which character belongs to which grade — so "grade 3" is a boundary you can verify, not a feeling. Every article here is machine-checked: if a single character sits above its grade, it is not published.

The result: you never hit a character you have not learned. That is the whole reason this product exists.
