As a result of surveys and investigations of the situation on the tenure of office in laborers engaged, in the period from September 1953 through October 1957, in the dam construction work for the development of the sources of electric power in Oi River (Ikawa-village, Abe-county, Shizuoka Prefecture), following conclusions were obtained.
1) The nuclei of the labor power in the dam construction work for the development of the sources of electric power are floating laborers and yet 70% of them are coolies.
2) Ingress or egress and transference among floating laborers are exceedingly frequent and the average length of their staying there was about 73 days. This period appeared to be extremely short, but this was because that those whose average length of stay was 60 days or less accounted for 42.7% and in particular it was made known that seasonal laborers utilizing the farmer's slack season occupied 22.7% of the whole floating laborers. Moreover, it was found that in such construction work, there was necessity, because of its character, for the exercise of a great deal of labor power and accordingly the number of days for their stay varied with the contents of the work, resulting in the utilization of seasonal laborers so as to make up for a large amount of labor in such a short period. Repetition of coming to this place twice, thrice or repeatedly every year is characteristic of seasonal laborers and their native places tend to be uniform.
3) Fifty four persons showed such a peculiarity that the length of their work was only one day, 21 of whom were occupatinal laborers representing 39.2% and it was conspicuous that 7 of them were in conjunction with oriminal acts.
4) In the population composition by age of floating laborers, the 21-25 age group accounted for the largestr poportion, this being the common phenomenon through all occupations.
5) That female laborers are few is due to the characteristic location of the dam construction in a mountainous remote place as well as to the unfitness of the type of the work for them.
