It is hand-dyed deeply with natural indigo and soaked at least 20 times!
The deeply dyed indigo blue is a Japanese traditional color.
It is said that Samurais liked and wore the color as a winning color to come back alive from battlefields in the Kamakura Period.
It is dyed in a natural indigo dyeing technique that ferments a Sukumo dye produced from indigo leaves by using only natural materials such as wood ash liquid, Japanese sake.
It is a environmentally friendly dyeing technique using without any chemicals.
「Dyeing liquid that ash liquid is used for the Sukumo fermentation is excellent in insect-proof , deodorant effects and bactericidal effects.
It depends on the individual but effective for skin diseases.
In addition not only various effects, I proud that but also the rich color stacked several times in the dyeing liquid produced by natural fermentation is the unique color seen like purple by sunlight or like dark blue depending on the weather that chemical dye can not express. I hope to enjoy that the color changes as time goes by.
Nowadays natural indigo dyeing things by a technique using ash liquid for fermentation are few in nunber.
It requires labor-hour and costs but we are particular about the technique to create genuine natural indigo dye. 」(Mr.Osawa, the producer )
