The history of this stadium involved many big changes and many different ideas. In February 2012, the government decided to build a new stadium for the Olympics. At first, a British architect named Zaha Hadid had a design with a retractable roof. However, the government changed the plans because of the high costs. They wanted a design that was more affordable for the country. In December 2015, the Japan Sport Council chose a new plan. This new design was made by the Japanese architect Kengo Kuma and the Taisei Corporation.

The Japan National Stadium is a massive multipurpose venue located in Tokyo. 
The stadium uses a unique architectural method that relies heavily on timber.
The stadium features different seating capacities depending on the type of event held. In its standard athletics mode, the fixed capacity is 68,089 people. However, the venue can expand to a total of 80,016 people. This is achieved by installing temporary seating over the permanent athletics track. This expanded capacity was utilized during the 2019 Rugby World Cup. For the Olympic Games, the capacity was originally planned at 60,102 to account for press and broadcasting equipment. During the Paralympics, the capacity was lowered to 57,750 to allow for more handicap accessible seating.
The history of the stadium involved significant changes to its design and budget. In February 2012, the Japanese government announced the reconstruction of the National Olympic Stadium. The original design was created by British architect Zaha Hadid. It featured a retractable roof and two massive steel arches. However, the government scrapped this plan in 2015 due to high costs and public discontent. Critics like Toyo Ito and Fumihiko Maki also expressed concerns about the design. Ultimately, the government sought a new bid that was more affordable.
In December 2015, the Japan Sport Council selected a new design team. This team included Japanese architect Kengo Kuma and the Taisei Corporation. Construction officially began in December 2016. The project was completed and handed over to the International Olympic Committee in November 2019. The stadium's inaugural sporting event was the 2019 Emperor's Cup final on January 1, 2020. 
There are several notable examples of the events held at this venue. The stadium has hosted major rugby matches, such as the Classic between Meiji University and Waseda University. 
The stadium connects to several broader systems, including environmental science and urban planning. By using domestic timber, the project supports local industries and reduces carbon footprints. The integration of solar panels and rainwater harvesting shows how large buildings can manage resources. The focus on accessibility provides over 450 spaces for wheelchair users. This ensures the venue is inclusive for all members of the public. As the stadium moves toward new ownership and naming rights, it remains a key part of Tokyo's infrastructure.
