In 1957, the author analysed the structure of climatic boundaries in central Japan, The following is an outline of the method used.<BR>a. Three hundred and sixty-five precipitation charts plotting the daily precipitation for 1955 (scale 1 : 1, 500, 000);<BR>b. Twenty-four charts plotting boundary lines between the precipition and non-precipitation areas, half-monthly for the year ;<BR>c. Recording, in areas 15 km × 15 km, the concentration of the boundary lines, half-monthly throughout the year ;<BR>d. Plotting lines of the heaviest concentration there by determing the climatic boundaries for each half-month ;<BR>e. Plotting on one chart the climatic boundaries for each half-month ;<BR>f. Recording, in areas of 15 km × 15 km, the lines of heaviest concentration thereby determining the climatic boundaries for one year.<BR>The author, in this late treatise, applies the same method to the northern and southern regions of Japan, thus completing the climatic boundary chart for the whole of Japan.<BR><I>Illustrations</I><BR>Figures 1, 2, 3 & 4 are examples of the charts made to determine the climatic boundaries. for each half-month.<BR>Figures 5 & 6 show the half-monthly. climatic boundaries, of each region, for the year. Figures 7 & 8 show the climatic boundaries, of each region, for the whole year.<BR>The chart plotted in Figures 7 & 8 bears close resemblance to the winter charts, thus demonstrating that the climatic boundaries of the winter months are most marked while these of the summer months are hardly determinable.
