Second and final part of an educational film for American school children forty years ago. I get many comments on the bath scene. When I was in Japan in the late fifties Japanese used to wash themselves   with soap outside a bathtub. The water in the tub was awefully hot. One had to sink in it very slowly. The whole family used to relax one after another in that same tub!  I took once such a bath in a small village and the whole population ran out to see me taking such a bath out in a shed with open door !
