Kanji are not letters. They are pictures that have been redrawn, simplified, broken, recombined and re-stylized for thirty centuries. The character on a SUMI shirt is the latest layer in a stack that begins on a turtle's underside.

The seven scripts — a vertical timeline
Shang Dynasty
c. 1200 BCE
KŌKOTSUBUN

The earliest known Chinese characters — incised on turtle plastrons and ox scapulae for divination. Pictographs of objects: a sun, a tree, a person.

甲骨文 — Oracle bone script
Zhou Dynasty
c. 1000 BCE
KINBUN

Cast into ritual bronze vessels for ancestors. Strokes thicken and round; characters become decorative, ceremonial, weighted with the authority of metal.

金文 — Bronze script
Qin Dynasty
221 BCE
TENSHO

Standardized by the first emperor across the unified empire. Long, balanced, near-symmetrical. Still used today on personal name seals (印鑑).

篆書 — Seal script
Han Dynasty
c. 200 BCE
REISHO

Born from the need to write fast — clerks compressed seal-script curves into flat horizontals and sharp diagonals. The shape of the modern character is set here.

隷書 — Clerical script
Tang via Nara
c. 700 CE
KAISHO

Crosses the sea to Japan with Buddhist monks and Tang envoys. Becomes the script of sutras, government, and the carved tombstone.

楷書 — Standard script
Heian Japan
c. 900 CE
GYŌ・SŌ

Court calligraphers in Kyoto begin writing kanji at speed and connection. Hiragana evolves out of cursive kanji as a Japanese phonetic script.

行書・草書 — Running & grass script
Today
2026 CE
SUMI

Three thousand years of brush tradition, reinterpreted on screen. We design each kanji digitally in our Tokyo studio — drawing on the discipline of Shodō — then print it to order on heavyweight cotton through our global production partners.
