Types of wood
Cypress (from Japan)
A high grade, long-life wood with durability, used in Buddhist temples. The color is bright and whitish at first, and gradually increases texture while aging.
Cedar (from Japan)
Matches very well with traditional Japanese rooms, and the grains create a vivid expression. The variation of colors and characteristics of each tree grows with time.
Spruce (not from Japan)
Fairly reasonable, and fits well with both Japanese and European spaces. Rather than the aging process, enjoying the new condition is preferred.
