This project aims to reaggregate census tracts from Japanese general and economic censuses taken since
2000. This aspect describes Tsukuba and the TX corridor on the eve of the first census and changes that
occurred since.
Up to the eve of the 2000 general census
Kawanaka and Kaneko (2015) divide the urban planning history of
Tsukuba into three periods. The period from 1963 to March 1980 is the central government period in which
planning and development were dominated by the central government's plan. The dominant tasks were layout
and construction of roads and institutes. The period from April 1980 through July
2005 is the government-private period during which the main tasks were construction of municipal, residential, commercial,
transportation, and cultural facilities. Tsukuba City itself did not come into existence until 1987. The opening of
the Tsukuba Express commuter line in August 2005 starts the third period in which Tsukuba planning is mainly local with the
central government's role gradually receding.
The scatter of institutes, residential and commercial areas, industrial parks, and older agricultural villages is a
legacy of the first proposal. This initial plan proposed a "Nouvelle Ville de Tsukuba", an essentially contiguous block
covering most of Yatabe-machi and Kukizaki-mura. Because Nouvelle Ville de Tsukuba would have displaced large numbers of farmers and villagers,
it met with fierce local opposition and was buried along with its name. Subsequent plans were restricted to forested areas
and minimized dislocation of existing residents
(Kawanaka and Kaneko, 2015). The
racetrack in the upper left quandrant of this diagram is the Japan Automotive Research Institute's Tsukuba test track, which
became operational in 1964.3 This plot of land will play a large role in Tsukuba's post TX
development.
The culmination of a national planning process that began in 1956
(Tanno et al., 2009),
Tsukuba Science City was originally a greenfields development plan to relocate a national university
and about 43 government research facilities to a location about 60 kilometers north of Tokyo. The site was noteworthy for its
lack of convenient transportation
(Bloom and Asano, 1981). Covering 2,968 ha, it was the largest
of the large-scale suburban residential development projects started in the 1960s
(Inui, 2017).
The original plan envisioned dividing the pine forests of the Tsukuba plateau into three basic land uses
(Tanno et al., 2009):
the science city, peripheral development districts, and industrial parks. Laid out along a north-south axis with universities to the north and research institutes to the
south, the plan called for a residential and retail district between them. New boulevards would connect this new city to commuter train stations in nearby
Tsuchiura and Ushiku. An expressway completed this early sketch.
The University of Tsukuba (formerly the Tokyo University of Education) and national research institutes were transfered to this science city
between 1972 and 1980. A central shopping mall, apartment complexes for researchers and a bus terminal
were completed between 1983 and 1985.
Features relevant to census tracts
Tsukuba City and the Tsukuba Express corridor contain several features that
are pertinent to observing changes in census tracts over time.
Agricultural districts and preexisting villages
Large-scale planned development preceeding main period of interest (2000-2020)
Based on national project with large-scale funding from national government
Central retail and residential area
University district
Research institutions, both in a district and scattered
Residential areas aimed at professionals
Industrial parks
Large-scale coordinated commuter rail and residential development
Based on national project with large-scale funding from national government
Residential development initiated with opening of Tsukuba Express commuter rail line in 2005
Retail development but no industrial development
Mergers of lower level communities to form new cities
Construction of new ring expressway linking radial expressways and Narita Airport
General censuses
General census tracts and Tsukuba urban plans
Census tracts for 2000 general census
Census tracts for 2005 general census
Census tracts for 2010 general census
Census tracts for 2015 general census
The above four maps show urban plans mapped onto census tracts for the respective general censuses. The color scheme
is borrowed from Figure 3-4 in
Kawanaka and Kaneko (2015).
Because several tracts almost identically
match residential housing developments (RDV), particularly in the southern tracts, those identified
in a 2017 survey of vacant housing were also added to these maps. The plan codes are as
defined in the table.

Tracts that are defined by or dominated by a plan are drawn with solid colors. Other plans that are covered by
larger tracts or are not yet defined by a plan are indicated with colored circles or triangles.
Tsukuba City's website lists nine industrial parks (IND). All were establisheb before 2000. Of the nine, seven have
2015 census tracts specific to them. Kamioshima Industrial Park at the far north and Tsukuba Research Park Hanare in the south are
part of larger tracts. Tsukuba Midorino Industrial Park is assigned a specific tract in the 2010 and 2015 censuses, but shares a larger tract with legacy land
in earlier censuses. Tsukuba West Industrial Park occupies the former Tsukuba Expo site and has a specific census tract
for all censuses covered by this project.
'Legacy' (LEG) refers to miscellaneous lands not covered by any other plan identified here.
Peripheral town revitalization (PTR) districts
were designated by Tsukuba City in 2017
Toyota, Hara and Nakanishi (2020)
as part of its R8 Regional Revitalization Plan. Tracts covering
parts of this plan are included here because of their historical significance. For example, Sakai-mura was designated in
1945 as a national new lifestyle model village
Toyota, Hara and Nakanishi (2020).
Several residential housing developments (RDV) closer to the Joban Railway define their census tracts. Because RDVs have
distinctive demographic patterns, those covered by the 2017 survey of vacant housing
were included in these maps even though they are not part of the master plans and may only occupy parts of census tracts.
(A 2006 table of old residential developments lists 36 developments.)
