Japan Blue Group was established in Kurashiki, Okayama in 1996. The infrastructure of the company includes workshop Kurashiki Peeping Indigo, a sewing factory Momotaro, as well as a coloring and post-processing section called Akasaki. The coloring process in Rampu-Ya according to the ancient coloring technologies is based on collection of Polygonum tinctorum leaves, their drying and composting. A special raw material called sukomo is then prepared, this procedure takes 3 full months. Highly alkaline solution is made called lye; ashes of hard rock trees are dispensed in hot water. Then sukomo raw material is mixed with lye solution and lime in a maturing pit, after which drowned raw material sukomo is poured into dye-bath and a bit more lye solution is added. All this is being fermented and as a result the foamy mass is produced called Ai no hana (indigo flower). After the mass is stabilized it is ready for fabric coloring. It is worth mentioning that Rampu-Ya colors not only denim, but also other fabrics brought by the clients.
