Review of ``Municipal Change Flip Map'' that shows how the scope and names of municipalities have changed due to repeated municipal mergers

Basic local governments in modern Japan are divided into

municipalities , but the breakdown of municipalities has changed due to repeated mergers, and even municipalities with the same name have different scopes, and municipalities that once existed are now different. It may have disappeared. The `` Municipal Change Flip Map '' created by Eicha (@eicha_plmap) is a website where you can see the changes in municipalities like a flip book, and you can actually check the changes in municipalities. I tried to.

When you access the municipal change flip map, the following screen will be displayed.

There are two versions of the flip map of municipal changes: a 'complete version' and a 'simplified version.'The complete version reflects the changes since the implementation of the municipal and town system systems in 1899, while the simple version focuses on

the great mergers of the Heisei era. It has become. This time, I will open the complete version of 'Tokyo'.

Then, the cities, wards, towns and villages of modern Tokyo were displayed color-coded. Yellow indicates 'city,' yellow-green indicates 'town,' light blue indicates 'village,' and pink indicates ordinance-designated city or special administrative district (ward).

In addition,

core cities that have been designated as cities have a red frame surrounding their city name.

If the map is not visible and you want to display the entire map, or if you want to enlarge the map, move the cursor to the magnification display of '20%' to '200%' at the top of the map and the display size of the map will change accordingly. .

When it is open, the municipalities as of the latest (April 1, 2015) are displayed, and when you move the cursor over the era on the left side, the division of municipalities for that era is displayed.

If you try displaying the cities, towns and villages on July 1, 1970, there are more green and blue colors than in modern times, and you can see that there were more towns and villages at a glance. Also, modern

Akiruno City was divided into Itsukaichi Town and Akita Town (Akikawa City just before the merger), Musashimurayama City (then Murayama Town), Higashiyamato City (then Yamato Town), and Higashiyamato City (then Yamato Town). It was also confirmed that Kurume City (then Kurume Town) had different names.

Immediately after World War II (January 26, 1946) it was like this. With the exception of

Hachioji City , Tachikawa City , and Tokyo City , it is a town or village, and Ogasawara Village (Ogasawara Islands) was under U.S. military control.

You can see that on July 19, 1900, individual towns and villages were fragmented to an extent that would be unimaginable in modern times.

On the municipal change flipbook map, by moving the cursor over the years on the far left, you can see the changes in cities, towns and villages, just like in a flipbook. You can check out the video below to see how the municipal change flip-flop map is actually used.
