It is considered the most prestigious juniper species in bonsai, prized for its dense, soft scale-like foliage and its capacity for dramatic deadwood artistry. The techniques of 'jin' (bleached dead branch stubs) and 'shari' (stripped bark revealing the heartwood) are most famously associated with this species. The Itoigawa variety, collected from Niigata Prefecture, is particularly revered worldwide for its exceptionally fine foliage.
