The footage was put together by pictures taken from the stationary camera fixed on the “Diamond and Flowers Ferris Wheel” located inside the Kasai Rinkai Park. The photos were taken from October 2017 until the construction was completed. You may see the process of the land formation using the heavy machineries. It is worthwhile to see the area excavated in a belt like way in the center, the piles of soil moved around the center, the construction process of the Olympic course, and the administration building .
