Bonsai pot shapes aren't just aesthetic choices — each traditional form carries its own history and its own set of unwritten rules about which trees it suits. Here's a working guide to the shapes you'll run into most, in plain English.
The rectangle and the oval — the workhorses
Rectangular and oval pots are the most versatile shapes in bonsai, and it's not close. Both give a tree room to establish visual “weight” at the base without competing with it. Rectangular pots tend to read as more formal and architectural — a natural pairing for upright, structured trees. Ovals soften that same footprint, which is why they're often the default choice for a huge range of styles.

Rinka — the scalloped rim
Rinka pots take a round or oval body and finish the rim in a repeating scalloped pattern, like the edge of a flower. It's a decorative touch that dresses up an otherwise simple form without changing the pot's proportions. Because the rim carries the personality, rinka pots often get paired with trees that want a slightly softer, more ornamental container — flowering and fruiting species in particular.

Hexagon and the four-sided box
Angular, geometric pots — hexagons and the square-cornered “masugata” (box) form — read as formal and deliberate. They're less common than rectangles or ovals, and that rarity is part of the appeal: a hexagonal or box-form pot makes a statement on its own, so it tends to work best with a tree whose own form is confident enough not to get overshadowed.
Round — the casual end of the spectrum
Round pots, and the deeper, more bowl-like “teppatsu” style in particular, read as informal and naturalistic — closer to something you'd find in nature than a piece of built architecture. They're a common choice for cascade and semi-cascade styles, where the pot's job is to visually support a trunk that's moving downward rather than a canopy spreading outward.
Mokkou — the lobed, quince-shaped pot
Mokkou pots take their name and silhouette from the quince fruit — a soft, multi-lobed outline instead of a straight-sided form. Like Rinka, it's a decorative shape, but the effect is different: Rinka dresses up the rim of an otherwise standard pot, while Mokkou changes the entire body outline. It's a distinctive look, and one best used deliberately rather than by default.
Rim styles: single, outer lip, and inner lip
Beyond the overall shape, the rim is finished in several ways. A single, plain rim (sometimes called hitoeguchi) keeps the top edge simple and unadorned. An outer-lip rim flares slightly outward, adding a bit of visual weight to the top of the pot. An inner-lip rim does the opposite — the lip turns inward, which is a more understated, refined look. None of these changes the pot's overall footprint, but they change how substantial or delicate the pot feels in the hand and on the bench.
Why does any of this matter
None of these shapes is arbitrary. A pot is doing real visual work — supporting a trunk, balancing a canopy, setting a mood — and the shape is the first decision that determines how well it does that job. When you're picking a pot for a tree, shape is worth deciding before glaze, before color, before anything else. Everything else can be adjusted around it; the shape is the foundation.
