The locational development of post offices and the spatial change of the mail transportation network in nagasaki prefecture, japan

Abstract

The purpose of this paper is to clarify the spatial organization of the postal network. For this purpose, this paper deals with the locational development of post offices (1871-1993) and the spatial change of the mail transportation network (1969-1993) in Nagasaki Prefecture, in which there are a large number of detached islands. The results of this analysis are summarized as follows: 1) The postal services of Japan started between Tokyo and Osaka in March 1871, and the service areas expanded to Nagasaki in December of that year. Thereafter many post offices were established in Nagasaki Prefecture. Particularly in urban area (e.g. Nagasaki and Sasebo), the locational densities of post offices became crowded. On the other hand, the development of networks in rural areas (particularly detached islands) was slow, therefore many post offices had to be established by the requests of local administrations. At the end of World War II, 92% of the cities, towns and villages as of 1912 got post offices. 2) After World War II, the locations of newly-established post offices were completely restricted within urban areas. On the contrary, postal agencies entrusted by the Ministry of Posts and Telecommunications were established in rural areas. As a result, the allocation of post offices in urban areas became closer, and the postal network was promoted into the rural settlements, too. Recently, because of depopulation and improvement of transportation facilities, collection-delivery post offices in rural areas have been changed into non-collection-delivery ones, non-collection-delivery ones in the outlying settlements also having been changed into postal agencies. © 1995, The Human Geographical Society of Japan.
