Stock Effects/Tech Book

　What is Tokyo Tech Book?

Tokyo has been working to solve various issues that require a technological perspective, such as disaster management and environmental issues, and has made many successful achievements. What Tokyoites take for granted, for example, earthquake and flood response, delicious water, clean air, trains that run frequently and on time, are some of those accomplishments that will be of value to people around the world. 　　　　　
Among the technologies that underpin such assets, we have compiled the technologies possessed by the Tokyo Metropolitan Government in this brochure. Through this Tech Book, we are taking the initiative in helping solve urban issues by introducing cities around the world to our advanced technologies and expertise in fields such as infrastructure development, disaster management and environment.

　What is “Stock Effects in Tokyo ”?

　Examples of stock effects in Tokyo were compiled to introduce the stock effects of infrastructure from an easy-to-understand objective and quantitative approach. 　　　　　
　The compound and synergistic effects of various infrastructures were analyzed for their contribution to the city’s development and maturation and arranged by the five fields of “Transit & Logistics,” “Disaster Management,” “Environment,” “Water & Greenery,” and “Tourism & Vibrancy.” Along with these, 34 examples of the infrastructure built by the TMG and their stock effects are introduced.

　※Stock Effects
