Tokyo is an urban area and not a city, made up of 23 municipalities inhabited by more than 26 million people. A megacity, the largest in the world according to the UN, held together by an endless network of subways and elevated railways. A "non-city" where the urban space seems endless, in stark contrast to that reduced and limited individual. Here the individual is to oscillate between the approval prison and the desperate need for identity, within a system in which work is the first reason for living.
