Summary Development of retaining wall using Japan cedar thined wood was tried. The method of construction cons idered as the reinforced earth method of construction applied to the banking slope, and was taken as the many anchor work method of construction which does not choose texture of soil in it. Thinned wood po ured processing and NZN into a columnar form of 100mm in diameter, and it used them for surface-of-a-w all material in order to enable exchange also of after construction. The anchor plate and tie bar which a re the reinforcement material in the ground were made into steel, and gave zinc plating. Three types wit h which slopes etc. differ were designed. The on-the-strength examination of the fruit size of an anchor d rawing-out examination and Japan cedar a test of bend strength considered the stability after whole cons truction. consequently, Japan cedar sowed into a columnar form which sawed up from thinned wood sur face-of-a-wall material using it law the slope was able to develop the reinforced earth method of constru ction which height can construct to 7.7-9m at the ten percent from 3 percent
