Actually, the products of this kind had been widely seen in 8th century, and one of good quality craft was stored in Shoso In, treasure museum in Nara Prefecture built in the 7th century.

But osiers and rattans require preparation before the creation. First, they need to be harvested, and then peeled, wet, and dried. The nature of the plants, soft when they are wet and hard when dried, is the key for this craft making.
