Grand Roof Ring
The Grand Roof Ring is a symbolic structure of the Osaka-Kansai Expo venue, representing the concept of the venue design: "diverse yet unified".
It is constructed using traditional Japanese "nuki" joinery, a method used in the construction of shrines and temples, combined with modern techniques.
It serves as the main thoroughfare of the venue, providing a smooth traffic flow, while simultaneously functioning as a comfortable space sheltered from rain, wind, and sunlight.

Sosuke Fujimoto / Sosuke Fujimoto Architects
"I want to create architecture like a forest."
After graduating from university, he did not attend graduate school or join an architectural firm. Instead, he spent a significant period of time, almost like a NEET, allowing him to dedicate himself fully to architecture.
His work ranges from residential to large-scale architecture, installations, and pavilions.
In recent years, he has won numerous international competitions, expanding his work globally.
His works, aiming to create architecture "like a forest," gradually diminish the presence of geometric elements in a gradient, blurring the basic elements of architecture such as walls and ceilings that clearly define the inside and outside of the building. This allows a natural connection between nature and structures.
A forest contains things that are necessary and unnecessary for the animals, people, and plants living there in a seemingly disordered way. However, this disorder allows for gentle connections and coexistence.
In creating architecture, discerning what is necessary and unnecessary for what is difficult.
It's exciting to see more and more of his works emerge, which take on the challenge of creating a forest by finding connections between nature and artificial objects that seem diametrically opposed.
