This calligraphy by Jiun Onkō revisits a story that is said to have happened in the year 520. Daruma meets Emperor Wu and is asked various questions about Buddhism – but his answers fail to satisfy the Emperor. Annoyed, the emperor finally asks him "Who are you?" to which the Daruma answers "I do not know". Thrown out of the court, the Daruma is believed to have taken refuge in a cave, where he sat in meditation for nine years.
The design
Bold brushstrokes render the phrase “I do not know” in Japanese calligraphy, anchored by a minimal silhouette of a meditating Daruma below. The composition balances strong ink texture with generous negative space for a refined, gallery-ready look – easy to pair with denim, a blazer, or your favorite athleisure. Clean lines and high-contrast detailing keep the kanji legible and striking from across the room.
The artist
Jiun Onkō (1718-1804) was a Japanese Buddhist monk, scholar, and master calligrapher of the Edo period. Renowned for uncompromising, powerful strokes and spiritually charged lettering, Jiun’s work bridges scholarship and practice – making this design both visually compelling and philosophically alive.
