National Stadium, formerly known as the World Games Stadium, was designed by Pritzker Prize winner Ito Toyo. Ito introduced design concepts such as an open stadium, urban park, and spiral continuum, redefining stadium designs in the 21st century. Ito erected a 20-meter-tall installation called “Flame” at the entrance, an artwork that mirrors the stadium itself by featuring a spiral structure. Additionally, the red steel pipe and plating resembles the Olympic flame, spiraling upwards to echo the stadium and exemplify athletes’ passion, energy, and vitality.
國家體育場原稱世運主場館，由曾獲得普立茲克獎的國際建築大師伊東豊雄設計。他以開放式運動場（Open Stadium）、都會公園（Urban Park）、螺旋連續體（Spiral Continuum）等作為設計主軸，重新定義21世紀運動場的相貌。
高達20米的入口迎賓地標《火焰》，創作者同樣為建築師伊東豊雄。此作品延續了建築體本身連續螺旋結構的律動，螺旋狀的紅色鋼管與鋼板迴旋向上，除了與建築語彙達到一致性的呼應外，其形象也如同運動會傳遞的聖火，展現運動員的熱情、活力與生命力。
