Sujibori is the outline structure of an Irezumi piece: the system of lines that sets its readability and its hierarchy. Suji means line or sinew, bori means carving. It decides where one form ends and another begins, which forms the eye meets first, and how much skin stays open.
The outline is not a tracing of the design, and it is not one continuous line drawn around everything. It is a hierarchy of contours with different jobs: the silhouette of the main subject, the long lines of movement, the interior marks. Some passages need no contour at all and hold their form through the contrast of black against skin. Everything the viewer reads, from across a room or twenty years later, is held by this system.

Traditional Context
Irezumi took its imagery from ukiyo-e, and the ukiyo-e line was a brush line: the block cutter's task was to carve the artist's drawn stroke so faithfully that the print kept its movement. The tattoo line inherits that origin. A sujibori should look drawn, not constructed. In the classical sequence the outline was completed first over the whole composition, so that the bokashi and the colour had a finished structure to work into.
The weight of the line was never uniform. The silhouette of the main subject was cut heavy; secondary forms lighter; the smallest interior marks lightest of all. This is the same logic a calligrapher uses within a single character, and it is the reason a classical backpiece can be read from the far side of a room before any detail is visible.

Structural Logic
Sujibori sets the reading order of the piece. A well-built outline is read in sequence:
Silhouette: the outer edge of the main subject, in the heaviest line
Movement: the long directional lines that carry the eye through the composition
Main subject: the forms inside the silhouette that identify what the piece is about
Details: scales, fur, petals, pattern, in the thinnest line
Line weight follows the scale of the element and its role in the composition, not only the zone of the body it sits on. A large wave on a forearm can carry a heavier line than a small flower on a back, because the wave is doing more structural work.
The main silhouette line should move the way a brush moves: long, free, continuous, confident. A silhouette built from short cautious segments reads as hesitation, and hesitation ages badly.
Not every edge needs a line. Where black meets open skin with enough contrast, the boundary already exists, and a contour laid over it only flattens the transition. Knowing where the line is absent is part of the hierarchy, not an exception to it.
The outline also holds the negative space. Where the line stops is as much a decision as where it runs, and open skin inside a sujibori is a form, not an absence.
The errors are consistent across bad work: one weight for every line, a main contour too weak to hold the piece, interior detail heavier than the silhouette that contains it, negative space lost to over-drawing, and a line that is technically unstable, wavering in width or depth so that it heals uneven.

In My Practice
My order of work does not begin with the final outline. The first marks on the skin are water-lines: a light layout that fixes the placement of the composition and nothing more. It is not sujibori, and none of its lines is a decision about weight.
Then comes the background. Only when the black masses and the gradients are in place can I see where a form is already held by contrast and where it needs a line to hold it. Some passages need no contour at all. The rest need a clear hierarchy of contours, each with its own purpose. Where each will fall can be planned before the work starts only roughly, so I leave that decision to the moment when the skin can answer it.
The final brush-stroke contour goes in last. The main silhouette is the heaviest line in the piece, and I want it to move like a calligraphic stroke, long and uninterrupted, because that movement is what the whole composition inherits. Secondary forms sit under it in a lighter line, interior detail lighter again, so that nothing inside a form competes with the form that contains it. On a large piece I check the result from a distance: if the silhouette does not read from across the room, the detail will not save it.
I keep the line stable because skin changes. A clean line of consistent weight heals predictably and stays readable for decades; an uncertain line only becomes more uncertain with time.
