Traditional Japanese farmhouses or rural houses called Minka in Ehime prefecture were investigated to analyze the relationship between the volume of wood timber and the number of wood species used in Minka and the local forest resources. Wood samples were taken from different parts, such as pillars, beams, rafters, and so on, of the farmhouses. The samples were prepared for microscopic observation with a magnification of 40-400x. From the observation of wood samples, the species of wood timber used in Minka are distributed in the area where houses are located. Major Japanese plantation wood Hinoki(Chamaecyparis obtusa) and Sugi(Cryptomeria japonica) are used for every part of Minka. Most of wood species are used because of their characteristics and properties.
