The chart above shows the evolution of street network disconnectedness of the most connected and most disconnected cities in Japan, for both new street additions (left) and the aggregate street network (right).
Japan in context: Street-network sprawl of new development
The level of street-network sprawl in new development in Japan followed a zig-zag trend with an overall increase. To get a sense of how street development has changed in Japan, we can consider three of its most populous regions: Saitama, Osaka and Aichi. Disconnectivity in the most populous cities in Japan follow the same country trend.
The largest city in Japan is Tokyo, with a population of 33195700 people. Taking into account the entire (i.e. aggregate) street network in Tokyo as of 2020, the overall level of street-network sprawl is 2.11, which is well-connected. The level of street-network sprawl in new development in Tokyo followed a zig-zag trend with an overall increase.
Japan in context: Aggregate street-network sprawl
As of 2020, the city with the most disconnected street network in Japan is Onomichi with an SNDi of 4.0, which is sprawly. Conversely, the most connected city is Yamagata with an SNDi of 1.29, which is very well-connected. See these two cities’ trends in the above graph, or dive deeper into each: Yamagata, Onomichi.
The level of street-network sprawl in the aggregate network in Japan rose steadily.
