No cleavage line patterns or tention lines of the skin of the Japanese monkey, <I>Macaca f uscata</I> (BLYTH, 1875) have been still demonstrated. The present investigation was made to obtain the information on skin tention lines of the Japanese monkey. In the present investigation, 3 male Japanese monkeys, ranging in CrownRump length from 410 to 600 mm, were used (Table 1) . All of the materials were fixed in formalin. The puncture wounds in the materials were prepared by the modified method (WAKURI, 1961a) of GARDNER & RAYBUCH (1951) .<BR>The patterns of the tention lines were found to be constant in the skin of all Japanese monkeys. The patterns of some variation were explainable on the basis that in the Japanese monkey there was little variation in body type. The patterns of the skin cleavage for the entire body of the Japanese monkey mostly were similar to that of the younger human fetus (50-60 mm) . When the pattern of the Japanese monkey is compared with the quadripeds (cat, goat, rabbit, pig, bovine fetus), striking differences could be noticed. The patterns of the tention lines in the Japanese monkey resemble rather to that of man (a diped) than that of the quadripeds.<BR>The patterns of the tention lines in the skin of the extremities of the Japanese monkey mostly appear parallel to the long axis of the extremity. However, in the anterior region of the knee, some transverse tention lines are observed. The direction of the skin cleavage in such region seems to be due to the adaptation of the cutis fibers to the mechanical function of the region.
