Japanese white pine
Pinus parviflora

Japanese white pine carries soft, blue-tinted needles in bundles of five rather than the stiffer two-needle bundles of black or red pine, giving it a notably gentler texture. It grows slowly, is usually grafted onto black pine rootstock for vigour, and is considered by many the most refined of the classical bonsai pines.
