Formal upright: coherence through restraint
In chokkan, the trunk rises vertically with visible taper, and the apex sits over the base. Branches usually diminish in scale and build a stable triangular outline, but exact symmetry can look mechanical. The form is convincing when the trunk, roots and branch spacing support the same story. A straight trunk with no taper is not automatically a strong formal upright.
Slanting: a whole-tree direction
Shakan leans in a clear direction while remaining visually anchored by the root base and counterbalancing branches. The lean should read through the trunk and canopy, not as a pot accidentally tipped on a bench. A strong root spread or a branch reaching into the open side can keep the design from appearing to fall.
Choose the line the tree can sustain
Start by rotating the tree and studying the nebari, movement, scars, branch positions and live veins. Ask which front makes the existing structure legible. The styling choice is strongest when it amplifies the tree’s evidence instead of concealing awkward transitions with wire. A useful design can combine qualities; the label is secondary to balance and health.
