Observing the variation of lumber demand in Japan for 45 years from 1955 to 1999, both the amount of demand for lumber and that for saw log show a maximum value in 1973 followed by a decreasing tendency after that. On the other side, the amount of demand for the pulp and chip material varied differently from the above things to increase until 1995. When the relation with the Japanese economic index is examined, a correlation is seen between the demand for the pulp chip and Japanese economic index, but no correlation is seen between amounts of other demand for lumber and Japanese economic index. To raise the utility of lumber, the concept for the consumption of the lumber must be reconsidered, and then the general consideration of the lumber circulation should be reexamined and expanded. It is suggested that we have to introduce a marketing technique to arouse the consumer’s needs for the lumber.
