The whole article covers the ways by which over eighty millions of people who are combined in the narrow limited land of Japan, can enjoy the higher level of livings, and can contribute to the development of the world civilization.
The conclusion is thus : -to make best of the resources they have which must be developed and utilized conprehensively. The author ficks up the hydropower resource-because this resource in Japan have been said to be abundant and in favorable conditions, but the whole quantity of it in Japan have not yet been known. -, he made through study to know the ultimate quantity of the theoretical hydraulic potential energy (T.H.P.E.) in Japan. The results of this study shows the T.H.P.E.in Japan amounts to 7.734 × 107 kwy namely 7 × 1010 kwh approximately, and the possible hydroelectric power shall be 108 kw when suitable load factor and development efficiency are assumed.
And then, he shows the best method of hydropower development in Japan and the kind of chemical industries to be encouraged as the key industry of Japan based on this electric and other resources.
Shortly speaking, when those items which are shown hereafter realized comprehensively, Japanese can enjoy a higher level of livings than they have been.
1. Development of hydropower by reservoir system to supply electricity whenever they want.
2. To change the base of industries from coal to hydropower to save coal which is deficient in Japan.
3. Full utilization of sea water and products as Japan is surrounded by sea.
4. To increase in production of fertilizer to give enough food for them.
5. To enlarge the chemical industries as above.
6. Development of forestry and encourage the chemical and other industries from forestry products.
7. To save coal and other fuels by electrification of rail roads, household facilities, and shutting up thermopower stations, etc to increase industrial row materials.
8. To enlarge such export industries as rayon and staple fibers, glass, fertilizers and so on based on their own resources.
