The net-migration by age and sex of prefectures in Japan, of 9 periods, each of which are of 5 years, between 1950 and 1995 were estimated.From these data, it can be pointed out that (l) the overall net-migration shows that the migration transition was observed in the past war Japan. (2) but, we cannot say so, if we observe net-migration of age groups of 10 and 14 and of 15 to 19, because they had been net-in-migration for all periods in metropolitan regions. Only age groups of ages between 20 and 34 had experienced migration transition, because their net-migration had changed from net-out-migration to net-out-migration in the metropolitan regions, (3) the migration history obtained from the accumulated net-migration in the metropolitan regions show that the migration transition did not ocured in Japan in a sense o effect of migration on the population distribution, because all age cohorts had an accumulated net-migration rate of over 100%, (4) the common pattern of net-migration rate by age groups observed in prefectures is that, in metropolitan regions, high rate of net-in-migration in the age groups between 10 and 19, and that, in non-metropolitan regions, rate of net-out-migration in the same age groups.

本文估计了1950年至1995年间日本各县按年龄和性别划分的9个时期(每个时期为5年)的净迁徙。从这些数据可以看出，L的总体净迁徙表明，日本在过去的战争中观察到了迁徙的转变。(2)但是，如果我们观察10和14岁以及15至19岁年龄组的净移徙，我们就不能这样说，因为他们在大都市区域的所有时期都是净移徙。(3)从大都市圈累计净迁徙获得的迁移史可以看出，日本没有发生人口迁徙对人口分布的影响，因为所有年龄段的累积净迁移率都在100%以上。(4)各地区观察到的各年龄段的净迁移率的普遍规律是，在大都市区，净迁移率的变化规律是：10至19岁年龄组的净迁入率较高，而在非大都市区域，同一年龄组的净迁出率较高。
