I am pleased to announce the launch of Tokyo 6420, a digital project on the Tokyo Olympic Games. Taking the name from the combination of the 1964 Games and the upcoming 2020 Games, Tokyo 6420 attempts to link together the story and cultural legacy of the Olympics in Tokyo with the urban transformation of the post-war Japanese capital. The Tokyo 1964 Games were one of the most successful Olympics of all time and it is this legacy that is driving the 2020 Games. As with 1964, 2020 is being seen as a redefinition of Tokyo and to a large extent, Japan itself. How the Olympics changed the face of Tokyo and how they are remembered and depicted in Japanese culture are the core questions this project is seeking to answer. Although this project has launched, it is an ongoing effort to chronicle the past and future of the Olympics in Tokyo and will be continually updated until the torch is extinguished at the close of the 32nd Olympiad in August 2020.
