In contrast to American rock and roll ideas about freedom and mobility, the Car Free Day is a celebration of human mobility, started way back when in Europe and now an annual event as part of Mobility Week.
An ever growing number of Japanese cities is participating in this event, with the 松本カーフリーデー above a regular participant, closing of a number of streets to automobiles.
Nine Japanese cities participated in 2009, according to Japan for Sustainability, and one can only hope this event grows even bigger, as Japanese city centres are surely ripe for more car-free zones.
The whole stretch between Matsumoto Station and the famous 烏城 or Raven Castle is an obvious candidate. One of my favourite candidates in Tokyo is the whole area around Jiyugaoka station. A popular high density urban transit node and trendy shopping district, the area is an intricate network of narrow streets and always seems to be a mess of cars still attempting, often aggressively, to assert their right of passage in what has become a defacto pedestrian zone.
