2020 Summer Olympics closing ceremony

The 2020 Summer Olympics cauldron was made for the 2020 Summer Olympics in Tokyo, Japan. In fact, there were two cauldrons, one inside the Olympic Stadium that was used only at the (opening and closing ceremony only) and the actual one, which was located on Tokyo's new waterfront on Ariake West Canal, which was lit after the Opening Ceremony and remained alight throughout the Games. The cauldron was designed by Canadian-Japanese designer Oki Sato, who attended Waseda University, the same university as Yoshinori Sakai, the cauldron-lighter in 1964. The steps to reach the cauldron, symbolising Mount Fuji, were "designed to evoke the image of a blooming sakura flower."Designed by Nendo founder Oki Sato, the white cauldron evokes the opening ceremony's concept of "All gather under the sun, all are equal, and all receive energy". The panels opened to reveal the Olympic torch, at the ending of the opening ceremony, and was lit by Japanese tennis player Naomi Osaka. "At the end of the opening ceremony of the Olympic Games, the cauldron 'blooms' to welcome the final torchbearer," said Nendo. "This expresses not only the sun itself, but also the energy and vitality that can be obtained from it, such as plants sprouting, flowers blooming, and hands opening wide toward the sky."The cauldron's flame was the first at the Olympics to burn hydrogen as a fuel. The hydrogen was produced via the electrolysis of water using solar power produced at a plant in the Fukushima Prefecture. Hydrogen produced by this process is known as green hydrogen. The hydrogen burns with an invisible, colourless flame unlike propane, which has is traditionally used as a fuel in previous Olympic flames. In order to create a yellow and visible flame, sodium carbonate is sprayed. "[We] adjusted the movement and shape of the flame to shimmer like firewood was stoked; such an attempt to 'design flames' was unprecedented." said Nendo firm. After the 2020 Summer Olympics,the true waterfront cauldron has remained in place as a reminder of the Games, as in 2016.
