Kuromoji / Lindera Umbellata

Supplier-disclosed industry ranges are 100 ml – 1 L for essential oil and 1–10 kg for dried branch/leaf material, with 4–10 week lead times. Production is artisanal and concentrated around small regional distillers in Gifu, Nagano, Tottori, Shimane, Kōchi (Niyodogawa), and the Mt. Hakusan area near Kanazawa. Annual capacity is finite per distiller; allocations to brand customers should be planned at the start of each calendar year.

Yes. Several regional kuromoji distillers operate from designated satoyama forestry programs and can issue origin documentation tying material to a specific forest or municipality. This is a meaningful positioning lever for craft-cosmetic brands; it carries premium pricing and lower-volume supply. Some distillers also operate under sustainable thinning and forest-management certifications.

Expect linalool content roughly in the 40–65% range for essential oil and around 55–60% for hydrosol, varying with region, season, and plant part (leaf, branch, or branch+leaf). Specify the desired plant-part composition and request a GC profile on the COA; for fragrance-critical applications, request batch-level GC rather than nominal spec ranges, since natural variation is meaningful.
