On a typical ride on the Tokaido Shinkansen traveling from Shin-Osaka to Tokyo, it does not take a childlike imagination to notice the view from the bullet train of scattered cars, small houses, and baseball fields, gradually changing as the train approaches its destination to packed apartment buildings and tall office towers. This is an important phenomenon of high-speed rail (HSR) implementation, which can be described by the terms “spillover effect” and “straw effect.”
High-speed rail investment: A butterfly effect for urban chaos
In 1969, Professor Edward Norton Lorenz coined the term “butterfly effect” to state that subtle changes in conditions can influence or cause seemingly unrelated results elsewhere. The flutter of a butterfly’s wings at place A can eventually develop into a hurricane at place B even though A and B are not related. Almost two decades after the term was coined, Japan National Railways (JNR) was privatized and split into several corporations, and now JR East manages the largest network of railway lines in Japan.
