In Japan, the chief sources of pulp, EZOMATSU (Picea alba) and TODOMATSU (Abies sachalinensis), has been decreased since the war due to overlumbering, They had to be replaced by other kinds of timber. For this purpose, red-pine has been used, More recently, broad-leaf trees have been increasingly used as the result of the introduction of new techniques, Broadleaf trees can be found everywhere in Japan, and accordingly the possibility of increased selfsufficiency is obtained in various regions of this country.
