What an enso is, how it relates to Zen Buddhism, why it is drawn in one stroke, and what to notice when you see one in a museum or temple.
- An enso is a circle drawn in one or two brushstrokes and is associated with Zen Buddhism.
- It is drawn once and not corrected, so the finished circle records a single movement.
- Some enso are closed and some are left open; both forms are common.
- The Zen monk Hakuin Ekaku (1686-1769) is one of the best-known painters of enso.

Spend more time with the brush
A private class is 90 minutes for up to five guests, so there is time to try forms beyond the basics.
What an enso is
Enso (円相) means circular form. In Zen art it refers to a circle drawn by hand with a brush, usually in one continuous stroke and sometimes in two. It is often written alongside a short inscription, but the circle itself is the main subject.
The enso is commonly associated with ideas from Zen Buddhism, such as enlightenment, emptiness, and completeness. Interpretations vary between teachers and between works, and the circle is usually left to the viewer rather than explained.
Why it is drawn in one stroke
An enso is not sketched first or traced over. The brush goes down, moves around, and lifts, and the circle is finished. Once drawn, it is not changed. This is why the shape is rarely a perfect circle: the speed of the hand, the amount of ink, and the texture of the paper all show in the line.
Zen practitioners connect the enso to wabi-sabi, the appreciation of beauty in imperfection. A slightly uneven circle, or one where the ink thins out and the brush hairs leave dry streaks, is not seen as a mistake.
Open and closed circles
Some artists close the circle, so the end of the stroke meets the beginning. Others leave a gap. An open enso is sometimes read as incomplete in a positive sense, leaving room for movement and development.
Neither form is more correct. When you see several enso side by side in a museum, it is worth comparing where each one starts, how thick the line is, and whether it closes.
- Closed enso: the stroke ends where it began
- Open enso: a gap is left in the circle
- Dry streaks in the line come from the brush running low on ink
Enso in Zen history
Many Zen monks in Japan were also calligraphers, and the enso appears often in their work. Hakuin Ekaku (1686-1769), a Rinzai Zen monk, is one of the best-known painters of enso, along with Sengai Gibon. An empty circle also appears in the Ten Bulls, a series of pictures traditionally used to describe stages of Zen training.
Drawing an enso is also described as a practice in its own right. Some practitioners are said to draw one every day, using it less as an artwork than as a way of noticing their state of mind on that day.
Trying an enso yourself
The tools are the same as for writing characters: a brush, sumi ink, and paper. Load the brush evenly, hold it upright, and decide on the size of the circle before you start. Then draw it in one motion without stopping to adjust. Your first attempts will probably be uneven, and that is normal.
In our classes at Shitaya Jinja Kaikan, the beginner session focuses on brush practice and writing characters, with a final piece to take home. If you would like to try an enso as part of your session, ask when you book whether it can be included; for more time with the brush, the 90-minute private class is more flexible.
