The decline in raw timber that has served as the material for this craft has become a growing problem and since 2006 there has been activity to protect and promote timber culture and sustainable forests. A “Nagiso Traditional Craft Forest” has been created and forests of zelkova, horse chestnut, and other trees that become materials for turning craft have been planted and maintained, while other modes of timber cultivation have also advanced. Raising good timber results in good product. The town of Nagiso will continue to pass down this culture in the future as the leading production region of wood turning craft in Japan.
