Each city has its own city-region around it outside the administrative boundary. The area does not stay fixed, but affected by the development of cily functions, undergoes continuous changes ; both the range and the structure of the area change according to the change of central place functions, the development of traffic facilities and the activities of regional economy, etc. In this article the writer deals with five main cities in Kyushu : Fukuoka, Kitakyushu, Kumamoto, Kagoshima and Nagasaki. The investigation was conducted into comparative analysis of the daily jaurney of workers commuting to these central cities from the surrounding countryside. The main points ascertained are as follows: 1 ) The labor of the five cities has grown rapidly in recent years. In consequence, the daily inflow of workers to these central cities strikingly increased in number from 1960 to 1965. The largest inflow in 1965 is found in Fukuoka (72, 269) and Kitakyushu (49, 249). They are followed by Kumamoto (18, 654), Kagoshima (14, 985) and Nagasaki (10, 735). It may be noted that the number is not directly proportional to the total resident population of the city. The rate of increase is highest also in Fukuoka (77.6%), which is closely followed by Kumamoto (62. 7%), and Kagoshima (54, 3%). Nagasaki (37. 3%) and Kitakyushu (35. 9 %) show a relatively low percentage. 2 ) Since the area of a city-region usually takes the shape of a starfish, it extends its range in three ways: the extension in a projecting direction (usually along railroad routes), the reclamation of a valley section and the filling-up of what may be called a caved-in part. The extension in a projecting direction grows sharper with a high and rapid growth of central place functions. Such cases are seen in Fukuoka and Kumamoto areas; the most example is the extension along the Nishitetsu Omuta Line in Fukuoka area, in which case the distance between the central city and the outer limit of the area is as long as 50 kilometers. 3 ) An inquiry into the number of commuters living in various municipalities indicates that, in the rate of increase in the number from 1930 to 1965, the municipalities of Fukuoka prefectures have the tendancy to rank highest and then come those of Kagoshima, Kumamoto, Nagasaki, and Kitakyushu prefectures. But, this order compared with that of the growth of their centrality (the rate of increase of labor absorbing power), the rank of Kagoshima and Kumamoto are reversed in the latter. The reason for this may be attributed to the fact that Kumamoto has an area in the shape of a concentric circle, that is to say the labor absorbing power is broken up in all directions to lessen its effect on each individual municipality. 4 ) Most of the coal-mining districts have strikingly intensified the relation to their central cities. This intensification, however, results not only from the increase of commuters to the central cities but from the relative rise of the rate of flow caused by the drastic decrease of the labor population in these districts. 5 ) Fukuoka and Kitakyushu area mingle with each other along the railway, the Kagoshima main Line. Within this mingling sphere Fukuoka area has been extending its range while Kitakyushu area has been retreating. This indicates that Fukuoka has a greater influence upon the sphere than Kitakyushu. The following conclusion may be drawn from the above. Fukuoka has the greatest labor absorbing power among the five cities in question, and the growth of its area has been the most striking. Kitakyushu has as large an area as Fukuoka, which extends as far as 50 kilometers in one direction, and the rate of flow of this area is high, but its growth is slowing down. Nagasaki area, which is small and narrow as a result of the geographical restriction, shows growth as dull as Kitakyushu. Kumamoto, the area of which has the shape of a concentric circle, does not have a powerful effect on each municipality within the area in spite of its st
