Tokyo's "Candidate City" bid for the 2020 Olympic Games was officially recognized in May by the IOC (International Olympic Committee), and it looks quite natural in view of Tokyo's reputation as a safe, clean and culturally rich megalopolis.
Indeed, it is rare to find among the major cities in the world, a city that is as free of crime, drugs, violent internal conflict, pollution and socio-religious taboos as the city of Tokyo. Besides, Tokyo left an excellent legacy after the 1964 Olympics in terms of sports venues, transport facilities and other infrastructure.
This point is very important for cities that want to hold the Olympic Games in the future, because it is generally believed that the financial burden of urban development and investment in infrastructure should not be too great a burden on the candidate cities. Tokyo, with its excellent public transport system and well-developed energy-saving devices, has an excellent claim to realize a compact and efficient great sports event.
