« tsunagiori » style folding
In a book published in 1797, Hiden Senbazuru Orikata , Gido Rokoan, a Buddhist priest who lived from 1761 to 1834, describes 49 models of cranes attached between they by the wings, the beak or any other part of the body. The models are obtained from a single sheet of paper, using more or less elaborate systems of slits. This type of folding, called « tsunagiori » style (tsunagi: connect, ori: to fold), makes it possible to constitute sets of cranes going from 2 until 97 in the book of Rokoan. In practice, some models can build as large as you want, by composing real tables.

Gido Rokoan's work consisted in imagining processes to obtain sets of cranes attached to each other by a system of cuts in a single sheet of paper. The basic principles of the tsunagiori style are:
- use of a single sheet of paper, square or rectangular, of which no part is removed,
- use of a system of cuts to produce sets of squares (from 2 to 100 ...), a square that can lead to a traditional crane,
- use of different systems of slits, to connect the cranes by the ends (wings, beak and tail) or by the body.

To do this, we cut, in a single square or rectangular sheet, squares delimited by slits occupying almost all the edges. So that the set of squares remains connected, we introduce connection points, that is to say, vertices that are not fully released (slits stopping a little before the vertex itself). Many variations are possible.

To implement such a folding, follow the following steps:
- make a map indicating the orientation of the cranes: location of the wings and the head,
- on the sheet to fold, mark the borders of the squares to accommodate the cranes,
- transfer to each square the pattern of folds of the bird base taking into account the map,
- pre-fold the assembly before making the cuts,
- make the cuts.

It only remains to do the folding!
