Indigo
Japanese indigo is celebrated as "Japan Blue." Hokusai and Hiroshige's ukiyo-e extensively used this deep blue, stunning European artists after Japan's 1853 opening. Van Gogh collected Hiroshige prints, and "The Starry Night"'s swirling blues were directly influenced by "The Great Wave off Kanagawa." The 30+ step dyeing process transforms fabric from yellow-green to deep blue through oxidation.
Natural indigo dye fermented from persicaria tinctoria (Japanese indigo) leaves.
Indigo symbolizes depth, focus, and endurance. Indigo fabric develops character with each wash.
Japanese indigo began in the Asuka period (538-710). It peaked in the Edo period with thousands of dye workshops nationwide.
Japanese indigo dyeing is extremely complex: persicaria leaves are harvested, fermented into "sukumo"; then mixed with lye and bran to create the dye vat. Cloth is dipped and oxidized repeatedly, transforming from yellow-green to deep blue over months.
