The Bonsai Koban pot 25cm turns a bonsai composition into a considered presentation. Its oval line follows the movement of the trunk gently and leaves more visual space around the tree, while the deep burgundy glaze adds a calm contrast beside the foliage and trunk. With a matching saucer in the set, it is an elegant choice for a shelf, table or display surface.

Three measurements that should not be confused
25cm is the commercial size name. For a real fit, use the measured external and internal pot dimensions.
- Outside: 27 × 21 × 7 cm (L × W × H).
- Inside: 23.5 × 18 × 6.5 cm (L × W × D).
- Saucer: 27 × 21 cm (L × W).
The roots decide. Check that the root ball can fit the inner space without excessive cutting or compression.
Deep burgundy glaze
It adds colour to the composition without overpowering the natural texture of the trunk and foliage.
Matching saucer included
It completes the presentation and catches water left after the pot has drained fully.
When this Koban fits
A bonsai pot is not selected from tree height alone. The actual root ball, the direction of the composition and the visual relationship between trunk and pot all matter.
Compositions with flowing movement
The oval form softens the outline of the composition and connects naturally with curves in the trunk or branches.
Deciduous and flowering bonsai
Glazed surfaces are often used with deciduous or flowering trees, though this is not an absolute composition rule.
The roots fit the 23.5 × 18 × 6.5 cm inner space without excessive removal.
The transition may require gradual root-ball reduction over more than one repotting.
If it cannot fit with safe root work, choose a deeper or larger pot.
Before repottingSize selection & fitWhat to check before the tree leaves its current pot.
Choose the pot around the root ball
Use the internal dimensions as the working limit, not only the 25cm size name.
Root ball and intended trunk position
Allow room for the roots, substrate around them and the position in which you want the trunk to stand.
25cm is not the usable inner space
The actual inner footprint is 23.5 × 18 cm and the available depth is approximately 6.5 cm.
Repotting follows the season and the species
The right timing and degree of root pruning vary by species and tree condition. Do not remove healthy roots simply to force a tree into a particular pot.
Placement guideRepotting in four stepsDrainage, placement, substrate and the first watering.
Repotting in four steps
Use a suitable bonsai substrate and keep the drainage holes clear.
Cover the holes
Secure suitable drainage mesh so it retains the substrate without restricting water flow.
Build the base
Add a thin layer of suitable substrate and shape the point on which the root ball will rest.
Position and secure
Set the trunk position, secure the tree where required and work substrate carefully around the roots.
Water until it drains
Let water drain fully through the base and empty the saucer before the final placement.
The saucer should not leave the roots standing in water
Use it to collect runoff temporarily, then empty it after every watering.

Ceramic construction
The product is stated to undergo an approximately 23-hour firing cycle at 1,240 °C. Small variations in the glazed surface are normal for a ceramic product.
Use with free drainage
Base holes release excess water. As no separate frost-resistance certification is stated, protect the pot from severe freezing conditions.
Clean surface and clear openings
Simple regular care protects the glaze and keeps water moving freely.
Do not leave the base of the pot standing in water after watering.
Use a soft damp cloth and avoid abrasives that could dull the glaze.
Remove mineral deposits or substrate residue before they restrict drainage.

Frequently asked questions
01What does “Koban” mean?
In bonsai-pot terminology, Koban refers to an oval form. The gentle curve of this pot creates a calm foundation for the composition.
02Is 25cm the external measurement?
25cm is the commercial size name. The pot measures 27 × 21 × 7 cm outside and 23.5 × 18 × 6.5 cm inside. Use the internal dimensions as the main guide when matching a tree.
03Is the saucer included?
Yes. The package includes a matching 27 × 21 cm saucer. Empty it after watering so the base of the pot does not remain standing in water.
04Glazed or unglazed for bonsai?
Glazed pots are often chosen for deciduous and flowering bonsai, while unglazed finishes are commonly paired with conifers. This is an aesthetic direction, not an absolute rule.
05Can it stay outdoors?
It can be used outdoors with free drainage. As no separate frost-resistance certification is stated, protect it from severe freezing conditions and impact.
06How do I know whether my bonsai will fit?
Compare the actual root ball with the usable inner space of 23.5 × 18 × 6.5 cm. If fitting it would require excessive root removal, choose a larger or deeper pot.
