Future in Tokyo 2 After WWⅡ, the city as far as the eye could see there was nothing but burnt-out ruins. But this tragedy has led to magnificent development economically since 1945. Therefore the history required the city to reconstruct by new materials as a revival city. Having reading Tange's book(1970),  I realised that he put forth their every effort in order to reorganise people and buildings naturally based on a new conception that the modification to very nature of the city.  He believed that the modification of the city's character was integrated harmoniously the conditions of life.  I noticed that this concept links to the aspirations of Carlsberg and Barbican. I believe that it is the essence for the city in the future, for our evolution process. In conclusion, the more spaces will have been reconstructed in Tokyo for the Olympics in 2020. I believe that a sense of crisis in Tokyo due to high dimensions can be transformed into rediscoveries in order to interact with people, buildings and nature. The baton from designers wished to make a 'new city' based on this principle in1945 has passed us. It is time to rediscovery historical and contemporary heritage. It will be the answer ----where is time and who we are.
