Ikkanbari bamboo craft is designated as a traditional handicraft by Kagawa Prefecture. It is a kind of papier-mâché technique, in which washi paper is pasted on wooden or bamboo frames then coated with persimmon tannin. Until plastic was introduced, persimmon juice was used in many ways such as vessels or base for lacquering. The Ikkanbari product is very strong and durable because of the water-proof and antiseptic property of persimmon tannin. It is subdued in color and has staid gloss. At the present time, items such as baskets, plates and small boxes are being made. Recently Ikkanbari is also favored as the material for Japanese-styled indirect lighting.
