A Study on the Back of the Road,

Factors Forming Streets, and Crime Relationships in the 23 Wards of Tokyo, Japan.

2023, Tokyo is the one of megalopolis. Tokyo has built a megalopolis unlike any other in the world.

The megalopolis of Tokyo is depicted in Japan’s representative culture, anime, and manga, and the city featured in the anime film “Akira” was constructed based on Tokyo, albeit as a fictional city called Neo-Tokyo,

Many fans from abroad visit Tokyo to see the world of Neo-Tokyo in person.

Director Otomo said, “I wanted to create chaos like that of the postwar reconstruction period and the Tokyo Olympics. ?It is fascinating to see a city (like Tokyo) that is so thoughtless, distorted, and changing at such a dizzying pace.

Is the chaos in the city of Tokyo from the postwar reconstruction period?

On the other hand,

Tokyo has many remnants of towns from the Edo period that have been left over to form Tokyo.

In his book “The Hidden City,” Maki writes

The streets that remain today from the pre-modernization era are not in good order.

There are many T-junctions, L-curves, and cul-de-sacs that are not part of the city.

Grit structural divisions, not central structural divisions, but chaos, maybe the difference.

These structures are based on the text of this book and my own experience in Tokyo with many architects and researchers, but I have not seen any discussion with actual data myself, so the actual situation is also unclear.

Step 1. 
Analyze the city’s streets.

As categorization, Streets were composed in the Edo period.
T Junction, L curve, Small cross, and Dead end street,
and the streets constructed by rapid economic growth and modern urban development are defined as streets constructed by high economic growth and modern urban development are defined as “Big cross” streets. In this book, we note that Tokyo’s streets have a lot of depth, We would like to measure the smallest point of each dead-end street to the smallest point of the main street and map the leading lines between the two points.

Step 2
the relationship between specific crime cases and street conditions

Using open data on crime published by the Tokyo Metropolitan Police Department, we would like to present the relationship between specific crime cases and street conditions (categorization of streets raised in Step 1) in each town.
