Forests cover 84% of Kochi and about 77% of Nara
Kochi Prefecture reports a forest share of 84%; Nara's forestry education material describes about 77%, or roughly 284,000 hectares, as forest. Forests cover most of both prefectures. But the sources differ in date and calculation conditions, so these percentages cannot compare timber output or sawmilling scale.
Among Kochi's examples of local timber are Yanase cedar from Umaji, cedar from Reihoku, and cypress from the Shimanto River area. 'Tosa timber' includes different species and producing areas.
Kochi dries and checks wood before it reaches buyers
Kochi aims to increase log production and link it to processing, distribution and sales. The prefecture says that efforts in drying and quality control have brought producers into contact with users in urban areas.
Work continues after a tree is felled: timber must be dried, brought to a suitable quality and connected to buyers. Extensive forest provides a resource base, but not every wooded area is harvested. Use depends on the site, species and management conditions.
Yoshino plants densely, thins repeatedly and grows trees for decades
Nara Prefecture describes Yoshino forestry as dense planting, repeated thinning and long growing periods. Trees are planted closer together than usual, thinned as they grow and cared for over a long span. Generations of work have shaped the quality of Yoshino cedar and cypress.
Nara's forestry education material names Kawakami, Higashiyoshino and Kurotaki as principal Yoshino areas. The methods described here do not apply to every forest in the prefecture.
Kochi's account highlights drying and quality control as timber moves toward its users. Yoshino's highlights shaping wood quality long before use. Beyond forest area, the time and work from growing a tree to using it distinguish these regions.
