Uemura's notes The Enji-wata () a cotton wool containing extracted dye compounds of lac dye and alum. The resultant colors of those dyed with this extract and those with the raw material would be similar. (Kirinketsu-zome) recorded in a manuscript from the Tempyo period (8th century AD), Japan is considered to be a dyeing technique with lac dyes. The resultant color was similar to that of cochineal dyeing, but was more purple.
