Rice bran from the outer skin of brown rice is processed into rice oil and used for cooking. Rice bran is also good as a pickling ingredient and as livestock feed. Before the turn of the century, when there was no such thing as beauty soap for the masses, women used it for skin care. Every woman had a small pouch filled with rice bran, and she washed her face and body with it when she took a bath. Rice bran is high in vegetable oil, protein, and vitamin B1. So it was indeed a wise and economical way to protect skin health.
Rice straw was an organic fertilizer and cooking fuel. Shredded and mixed with bran, it was used for chicken feed. When burned, it became ash for charcoal braziers and hearths. Rice straw was also woven into rope, containers, bags, hot pads, baskets, brooms, cradles, toys, sandals, snow boots, cushions, stools, various other handicrafts, and Shinto ceremonial ornaments.
