Geographic templates of Japan for maptile

We have made the geographic templates of Japan available in maptile, a map creation program for stata. For example, you can make a map like this easily.


List of geographic templates of Japan
Geographic template name Description
jpn_pref Prefectures
jpn_mun2000 Municipalities as of October 1, 2000
jpn_mun2005 Municipalities as of October 1, 2005
jpn_mun2010 Municipalities as of October 1, 2010
jpn_mun2015 Municipalities as of October 1, 2015

The templates for Japan can be installed by running the commands:

maptile_install using "http://www.crepe.e.u-tokyo.ac.jp/material/geo_jpn_pref.zip"
maptile_install using "http://www.crepe.e.u-tokyo.ac.jp/material/geo_jpn_mun2000.zip"
maptile_install using "http://www.crepe.e.u-tokyo.ac.jp/material/geo_jpn_mun2005.zip"
maptile_install using "http://www.crepe.e.u-tokyo.ac.jp/material/geo_jpn_mun2010.zip"
maptile_install using "http://www.crepe.e.u-tokyo.ac.jp/material/geo_jpn_mun2015.zip"


What is maptile?

It is a stata program written by Michael Stepner that makes mapping easy. It divides the areas on the map into groups (such as state, county, province) and shades them according to the value of the variable. The map itself is drawn using geography templates, which can be downloaded here. Now, there are 18 templates of United States and Canada.

Once you install maptile and geographic templates, you can make your maps anytime without any further installation. Michael Stepner provides a detailed introduction of maptile at this slide deck. Here, we skip the introduction so please look at this page.


Geographic template: jpn_pref

jpn_pref generates a map of Japan prefectures. This template does not display Northern Territories and Ogasawara Village for ease of viewing.


Geographic ID

You need to check whether your dataset contains a proper geographic ID, which associates each observation with an area group. If no geographic ID is specified, the default ID will be used.

Geographic ID Description
pref 2-digit prefecture codes (numeric)
prefname prefecture name in English
prefname_jpn prefecture name in Japanese

To-do-fu-ken (prefecture) identification code (JIS X0401) is used as prefecture code. JIS X0401 is the latter part of ISO 3166-2:JP after a hyphen, which is another common identification code of prefecture. Type names of prefectures (i.e., To, Fu, Ken) are removed from prefname and prefname_jpn (e.g., Tokyo-to → Tokyo).

Options

Option Description
geoid(varname) It specifies the geographic ID variable to use; default is geoid(pref)
simple It only displays large islands greater than 500 squared kilometers
compressed It moves Okinawa prefecture to the top left of the map


Option: simple

With this option, the map only displays large islands greater than 500 squared kilometers. Since there are tons of small islands in Japan, it makes your map simpler.

maptile population, geography(jpn_pref) simple



Option: compressed

This option moves Okinawa prefecture to the top left of the map, making it "compressed".

maptile population, geography(jpn_pref) compressed


These options can be used together.

maptile population, geography(jpn_pref) compressed simple



Geographic template: jpn_mun series

jpn_mun2000, ..., jpn_mun2015 generate a map of Japanese municipalities in each resepective year. The boundaries are based on the Population Census conducted on October 1 of each year. For example, jpn_mun2015 is the map of municipalities as of October 1, 2015. Those templates do not display the Northern Territories or Ogasawara Village for ease of viewing.

maptile density, geography(jpn_mun2015)

Data: population density from 2015 Population Census




Geographic ID

You need to check whether your dataset contains a proper geographic ID, which associates each observation with an area group.

Geographic ID Description
mun 5-digit municipality codes (numeric)

Si-ku-cho-son (municipality) identification code (JIS X0402) is used as municipality code. Check digit is not included.

Options

Option Description
compressed It moves Okinawa prefecture to the top left of the map
district It outputs all ordinance-designated cities in district level

Option: district

There are 20 ordinance-designated cities in Japan as of 2018. Each ordinance-designated city has several administrative districts. As default, ordinance-designated cities are outputed in city level. This option outputs these cities in district level. Tokyo's 23 wards are ouptutted in ward level either with or without the option. A full list of ordinance-designated cities is avilable in this page.

  • Tokyo-to (except islands), Saitama-Ken, Chiba-ken, Kanagawa-ken without option
  • local area inrange(mun, 11000, 14999) & !inrange(mun, 13360, 13421)

    Option: compressed

    This option moves Okinawa prefecture to the top left of the map, making it compressed as same as jpn_pref.
