Other notable styles include Windswept (Fukinagashi), Literati (Bunjingi), Multi-trunk (Kabudachi), Double Trunk (Sokan), Raft (Ikadabuki), Forest (Yose-ue), and Bonsai Rock (Ishisuki).

Characteristics of the Formal Upright (Chokkan) Style
The Formal Upright (Chokkan) style is a standout in bonsai, celebrated for its symmetry and elegance. It features a straight, upright trunk and evenly spaced branches, creating a balanced look. Understanding the Chokkan style’s characteristics can enhance your appreciation of its beauty. It also allows you to integrate mindfulness training and seiza meditation into your bonsai journey.

Straight, Upright Trunk
The defining feature of the Formal Upright style is its straight, vertical trunk. The trunk should rise from the soil in a nearly perfect vertical line, without any curves or bends. This upright posture represents a tree that has grown in ideal conditions, undisturbed by external forces such as wind or other environmental factors. The straight trunk symbolises stability, strength, and a sense of inner peace, much like the practice of seiza meditation encourages a grounded and centred state of being.
Tapering Trunk Thickness
In addition to being straight, the trunk of a Formal Upright bonsai should taper gradually from its base to its apex. This tapering, known as the “takenoko” or “bamboo shoot” shape, adds visual interest and realism to the tree. The thicker base represents the tree’s stability and connection to the earth, while the narrower top suggests its reaching towards the sky. This gradual tapering also draws the viewer’s eye upward, encouraging a sense of upliftment and aspiration, similar to the effects of mindfulness training and meditation.
Symmetrical Branch Placement
The branches of a Formal Upright bonsai are arranged in a symmetrical, balanced manner. The first branch, known as the “first left” or “first right,” emerges from the trunk about one-third of the way up and sets the stage for the rest of the branch structure. Subsequent branches alternate from side to side as they ascend the trunk, with each branch slightly shorter than the one below it. This orderly, symmetrical branch placement creates a sense of harmony and balance, reflecting the inner equilibrium cultivated through practices like seiza meditation and mindfulness training.
The Formal Upright style embodies the essence of bonsai: a perfect balance of nature and human intervention, a living sculpture that invites contemplation and inner peace.
By studying and appreciating the characteristics of the Formal Upright bonsai style, you can deepen your understanding of the art form. This understanding can infuse your bonsai practice with a greater sense of mindfulness and serenity. As you work to create and maintain a Chokkan-style bonsai, remember to approach the process with patience, care, and a clear, focused mind – the same qualities that underlie the practices of seiza meditation and mindfulness training.
Creating a Formal Upright Style Bonsai
Creating a stunning formal upright style bonsai, also known as Chokkan, demands patience, skill, and attention to detail. This traditional bonsai style features a straight, vertical trunk and symmetrical branch placement. It represents trees that have grown in open areas with unobstructed sunlight. To create your own Chokkan bonsai, follow these essential steps.

Selecting the Right Tree Species
When choosing a tree for your formal upright bonsai, select species with naturally straight trunks and dense foliage. Favourite species include:
- Junipers, such as the Shimpaku juniper
- Pines, like the Japanese Black Pine and White Pine
- Redwoods
- Cryptomeria
Choose a healthy, vibrant tree with fresh, green leaves or needles. You can grow your bonsai from seed, a cutting, or a pre-existing plant.
Pruning Techniques for Chokkan Style
Regular pruning is key to maintaining the straight, upright trunk of the formal upright style. Remove large branches and those with unnatural twists or unsightly appearances. Trim twigs and branches on the canopy to allow light to filter through and reach the lower branches. This helps shape the canopy and maintain balance.
The branching in the formal upright style should begin at about 1/4 of the total length of the trunk, highlighting a specific guideline for branch placement.
Wiring and Shaping the Trunk and Branches
Wiring is essential for guiding the trunk and branches into symmetrical placement. When wiring your formal upright bonsai, consider these tips:
- Use annealed copper or aluminum wire, depending on the thickness of the branches.
- Begin wiring from the trunk and work your way up to the branches.
- Gently wrap the wire around the trunk and branches at a 45-degree angle.
- Avoid crossing wires or applying too much pressure, which can damage the tree.
Bonsai Style | Trunk Characteristics | Branch Placement |
---|---|---|
Formal Upright (Chokkan) | Straight, vertical trunk with tapering thickness | Symmetrical, starting 1/4 up the trunk |
Informal Upright (Moyogi) | Curved or slightly slanted trunk | Asymmetrical, following trunk’s curves |
Slanting (Shakan) | Trunk grows at an angle, as if influenced by strong winds or growing on a slope | Branches grow opposite the direction of the slant |
By carefully selecting the right tree species, employing proper pruning techniques, and skillfully wiring and shaping your bonsai, you can create a stunning formal upright style bonsai. This bonsai showcases the beauty and elegance of nature in miniature form.
Formal Upright Style Care Tips
For your formal upright style (chokkan) bonsai, regular, light watering is key, done once a day. Post-pruning, a deeper soak is necessary to aid recovery and foster growth. A bonsai turntable can help in ensuring balanced growth and symmetry by facilitating easy rotation and sunlight exposure.
Fertilising your bonsai is vital for its health and vitality. Use a balanced 7-7-7 fertiliser every two weeks during the growing season. For smaller trees, liquid fertiliser is better, while larger ones benefit from granular. Always dilute the fertiliser to half-strength to avoid overfeeding, which can damage the roots.
A bonsai is not a genetically dwarfed plant, but a tree that the grower chooses to keep small through consistent care and pruning.
Choosing the right pot is critical for your bonsai’s health. It must have drainage holes to prevent root rot. The pot’s size should match the tree, with a depth that supports the roots without being too large. A well-draining soil mix is also essential for your chokkan bonsai’s success.
To promote healthy growth and maintain the tree’s upright trunk, place it in a well-lit area. Most bonsai species need 4-6 hours of direct sunlight daily, though some can tolerate partial shade. Regularly check for pests or diseases and address them promptly to keep your bonsai in excellent condition.
Care Aspect | Recommendation |
---|---|
Watering | Light, daily watering; deeper after pruning |
Fertilising | 7-7-7 fertiliser every 2 weeks during active growth |
Potting | Well-draining pot with adequate drainage holes |
Lighting | Ample light exposure; 4-6 hours of direct sunlight daily |
By adhering to these care tips and attentively meeting your formal upright style bonsai’s needs, you’ll cultivate a stunning and healthy tree. It will beautifully showcase the elegance and grace of the chokkan style.
Comparing Formal Upright to Other Bonsai Styles
The formal upright style, or chokkan, is a timeless favourite in bonsai. Yet, it’s vital to see how it stacks up against other styles. This comparison deepens our appreciation for bonsai’s diverse world. It helps us find the ideal style that matches our taste and skill level.
Informal Upright (Moyogi) Style
The informal upright, or Moyogi, is a captivating mix of the formal upright and slanting styles. Its trunk curves in a gentle ‘S’ shape, with branches sprouting at each bend. This style mirrors the natural growth of trees, with a trunk that tapers but less rigid than chokkan.
Moyogi appeals to those who love the elegance of formal upright but seek a more organic look. It’s a great choice for those who enjoy creative freedom. The informal upright style suits many tree species, making it a favourite among bonsai artists.
Slanting (Shakan) Style
The slanting style, or Shakan, showcases trees’ resilience and adaptability. Unlike chokkan, Shakan’s tree leans at 60-80 degrees, often due to wind or snow. This unique shape is a testament to nature’s power.
Shakan bonsai develop strong roots on the opposite side to balance and stability. The first branch grows opposite the lean, creating a striking contrast. While chokkan values symmetry, Shakan celebrates nature’s imperfections and the tree’s ability to thrive.
Style | Trunk Shape | Branch Placement | Overall Appearance |
---|---|---|---|
Formal Upright (Chokkan) | Straight, vertical | Symmetrical | Balanced, refined |
Informal Upright (Moyogi) | Gentle ‘S’ shape | Emerging at each turn | Naturalistic, flowing |
Slanting (Shakan) | Leaning at 60-80 degrees | First branch opposite lean | Dynamic, resilient |
Understanding each bonsai style’s unique traits helps in choosing the right one for your project. Whether you’re drawn to the elegance of formal upright, the organic charm of informal upright, or the dynamic resilience of slanting, each style offers a unique way to express creativity and connect with nature through bonsai.
