IWCS team was honored to document three 2020 Tokyo Olympic facilities: The New National Stadium, Olympic Village, and Olympic Gymnastic Centre, all with different designs but share the same goals - to use domestic wood as the building material to demonstrate Japanese culture, to show sustainability and to build a legacy. With tremendous help from the Tokyo Organizing Committee of the Olympic and Paralympic Games, Japan Sport Council, Taisei Corporation, Kengo Kuma & Associates, Nikken Sekkei LTD, Shimizu Corporation, Gifu Prefectural Government, Nakatsugawa City, Kyushu Electric Power Co. Inc. and Kyushu Rinsan Corporation, NPO Regional Exchange Center and Legacy of Wood Culture Promotion Council (LWCPC), we were generously given an unique opportunity to interview various representatives and experts who shared ideas and concepts, including the wood supply from around Japan, of these three Olympic facilities. Throughout the the informative tours around Tokyo, Gifu and Kyushu, we also realized it is absolutely crucial to introduce the design and construction process including the wood source, and how wood will play an important role in the upcoming 2020 Tokyo Olympic and Paralympic facilities towards the goals of sustainability and legacy.
