What is the Address Organization Project?

The current method of displaying addresses and locations in Inagi City uses land numbers known as "chiban."
Chiban were originally established not to identify places of residence, but were primarily assigned to land for tax purposes during the Meiji era.
As a result, every time land is subdivided or roads are developed, the regularity of the numbers is lost, leading to a confusing situation where numbers are skipped, and multiple houses are built on the same chiban.
To resolve this situation, we are working on organizing clearer addresses and location displays.

Effects of Address Organization

Address organization, along with the review of town areas and the establishment of blocks, can improve the convenience and safety of citizens' lives by organizing the display of addresses and locations. Additionally, it allows for the understanding of the number of households in each town area, which can lead to improvements in community activities and also has expected effects on responses during disasters.

Address Organization Methods

There are two methods for address organization: "Town Boundary and Town Name Numbering Organization" which renumbers land parcels, and "Residential Addressing" which assigns addresses based on the location of buildings.

Current Situation of Inagi City

Inagi City was established in Meiji 22 when six villages, Yanokuchi, Higashi-Naganuma, Omaru, Momura, Sakahama, and Hirao, merged to form Inagi Village. Later, in Showa 24, the Oshitate District was incorporated, and with the increase in population, it became Inagi Town in Showa 32 and Inagi City in Showa 46. With the progress of the Tama New Town project, the Koyodai District, Nagamine District, and Wakabadai District were created, and together with the previous seven districts, it is now composed of ten districts.
Regarding the organization of addresses, in line with the opening of the Tama New Town area, town boundary and name numbering organization was carried out in the Koyodai District in Showa 62, in the Nagamine District in Heisei 6, and in the Wakabadai District in Heisei 10. Additionally, in the existing urban area, town boundary and name numbering organization was implemented in parts of the Hirao District in Heisei 2 and Heisei 5.
