Kaisho Basics: A Complete Guide to Regular Script Calligraphy
When you begin studying Japanese calligraphy, the first script you learn is kaisho (楷書) — regular script.
In kaisho, every stroke is written deliberately and completely, with no abbreviation or joining. It forms the foundation for all other scripts. You cannot write beautiful gyosho (semi-cursive) or sosho (cursive) without a solid command of kaisho.
Even now, I practice kaisho regularly. Returning to the basics shows me whether my lines are honest and strong. Kaisho is not a "simple" script — it is one you spend a lifetime deepening.
This article covers everything you need to know to begin your kaisho journey, from its historical roots to practical techniques and training methods.
What Is Kaisho? The "Model Script" Among the Five Styles
Chinese characters have five major script styles: tensho (seal script), reisho (clerical script), sosho (cursive), gyosho (semi-cursive), and kaisho (regular script).
Kaisho is the most recently developed of the five. It was refined during the Wei-Jin period (3rd–6th century) and reached its golden age during China's Tang Dynasty. The great Tang masters — Ouyang Xun, Yu Shinan, Chu Suiliang, and Yan Zhenqing — remain the standard models for kaisho study to this day.
The character 楷 itself means "model" or "standard." Kaisho is literally the "model script" — the style chosen whenever clarity and precision matter most: official documents, textbooks, and printed text.
The Eight Principles of Yong — Mastering Basic Strokes
The cornerstone of kaisho training is the Eight Principles of Yong (永字八法). This ancient teaching states that the single character 永 ("eternity") contains all eight fundamental strokes of kaisho:
- Soku (側) — The dot. Place the brush at an angle and press firmly.
- Roku (勒) — The horizontal stroke. Draw left to right with controlled entry and exit.
- Do (努) — The vertical stroke. Pull straight down with a centered, stable line.
- Teki (趯) — The hook. Flick upward-left from the end of a vertical stroke.
- Saku (策) — The rising stroke. A short upward-right stroke with energy.
- Ryaku (掠) — The left sweep. Gradually release pressure as you sweep left.
- Taku (啄) — The short left stroke. A sharp, pecking motion.
- Taku (磔) — The right sweep. Gradually open the brush, pause, then sweep right.
Practicing these eight movements repeatedly builds the muscle memory you need for any kanji you encounter.
When I hit a creative block, I always return to 永. A single character, yet it reveals every weakness and habit in my brushwork. Kaisho practice begins and ends with 永.
Five Keys to Beautiful Kaisho
1. Master the Three Phases of Every Stroke
A kaisho stroke is not simply a line drawn across paper. It has three distinct phases: entry (shihitsu), travel (sōhitsu), and exit (shūhitsu).
The angle at which you touch the paper, the speed at which you move the brush, and the decision to stop or sweep at the end — being conscious of these three stages transforms the quality of your strokes immediately.
Pay special attention to gyaku-nyū (reverse entry): briefly moving the brush in the opposite direction before beginning a stroke. This creates strength and dignity at the start of each line.
2. Tilt Horizontal Strokes Slightly Upward
Horizontal strokes in kaisho are not perfectly level. They rise gently to the right at roughly 5–7 degrees. This convention, rooted in classical Chinese calligraphy, compensates for an optical illusion: a truly horizontal line appears to sag to the right.
Be careful not to exaggerate the tilt — too steep and the character looks unstable.
3. Keep Vertical Strokes Centered and Straight
The beauty of a kanji often depends on its vertical strokes. When the center vertical is perfectly straight and properly positioned, the entire character feels balanced — even if other strokes are slightly imperfect.
Practice with characters like 中, 申, and 年, where the central vertical dominates.
4. Balance Left and Right Sweeps
In characters like 大, 人, and 文, the left and right sweeping strokes mirror each other. Achieving balance between them is crucial.
The key: write the left sweep thinner and faster, and the right sweep thicker and slower. Giving more visual weight to the right sweep creates a grounded, dignified impression.
5. Embrace White Space
Beginners often try to fill every inch of the paper. In calligraphy, white space is part of the work.
In kaisho, the spatial arrangement between strokes — called kanka kekkō — determines beauty as much as the strokes themselves. Give as much attention to spacing as to brushwork.
How to Practice Kaisho — MUKYO's Recommended Method
Step 1: "Read" the Model Before Writing
Before picking up your brush, study the model carefully.
- What angle are the horizontal strokes?
- Where do the vertical strokes pass through the character?
- How is space distributed between strokes?
- Where are the thick and thin contrasts?
Understanding with your eyes first, then writing — this order matters.
Step 2: Write Large
Start by writing one character per sheet of hanshi paper, or even one character per quarter-sheet. Writing large forces you to slow down and become conscious of each stroke.
You cannot hide mistakes in large characters.
Step 3: Repeat the Same Character
Do not move to a new character after one sheet. Write the same character at least ten times. Compare your first and tenth attempts — the difference in line quality will be visible.
I often write a single character thirty times or more. Repetition teaches your body what your mind already knows.
Step 4: Study the Tang Dynasty Masters
Once you have a foundation, challenge yourself with classical copybooks (hōjō):
- Ouyang Xun's "Jiucheng Gong" — The pinnacle of precise, intellectual kaisho
- Yan Zhenqing's "Duobao Pagoda" — Powerful, majestic brushwork
- Yu Shinan's "Confucius Temple" — Warm, graceful elegance
Each master has a distinct personality. Studying them helps you discover the style of kaisho that resonates with you.
Kaisho Is Not Boring
Some people find kaisho dull — too slow, too rigid, too repetitive compared to the flowing movements of cursive scripts.
But the depth of kaisho reveals itself only through sustained practice. The same "horizontal stroke" can express entirely different emotions depending on subtle variations in thickness, speed, angle, and ink volume. A single dot contains a drama of entry, turn, and stop.
Kaisho is the script that holds the greatest expression within the smallest movements.
When I perform live calligraphy before an audience, what captivates people is not flashy gestures — it is the fundamental strength in each stroke, built through years of kaisho practice. That foundation powers everything I create.
Conclusion — All Roads Lead to Kaisho
Kaisho is both the starting point and the destination of calligraphy.
No matter how advanced your skills become, you will always return to kaisho fundamentals. "Ichiga nyūkon" (一画入魂) — pour your entire spirit into a single stroke. That accumulation will transform your calligraphy.
Start with the character 永. Practice the eight fundamental strokes with care, and enjoy the quiet conversation between brush and paper. As a calligrapher, nothing would make me happier than knowing this article helped you take that first step.
Begin your calligraphy journey with kaisho.
