At the RITE Future Forest, a demonstration plant exhibited by the National Institute of Global Environmental Technology (RITE) at the 2025 Japan World Exposition (Osaka-Kansai Expo), we provided comprehensive production from planning, concept design, architecture, displays design and supervision to operational support. The facility is engaged in demonstration experiments of future technologies that are expected in the future by combining both DAC (Direct Air Capture)*1, which directly captures carbon dioxide from the atmosphere, and CCS (Carbon dioxide Capture and Storage)*2, which stores carbon dioxide directly from the ground. This project aims to create a new forest in the future, by capturing carbon dioxide emitted by humans with human power. In the Guidance Building, we also worked on architecture as a demonstration experiment for new technologies, and realized the world's first future wooden construction technology, the CLT*3-fold structure hanging method, based on the concept of the forest of the future. The hang-up method is a conceptual method in which triangular CLT panels that are tightly connected to each other by hinge hardware are laid on a horizontal surface, and a specific part is lifted by a crane to deform it like origami under its own weight to form a folding plate structure. This time, by using this construction method, it was also an architectural demonstration project to create a large space with a structure with an expressive expression and to promote the spread of CLT structures that have both concept design, functionality, and construction. As a result, an architectural space that exudes a sacred atmosphere that exudes a sense of tightness has emerged, and the CLT folding structure itself made of domestic cedar has become a unique building that realizes an acoustic environment like a concert hall that resonates with displays videos and performances. After the exhibition, there are plans to relocate to the RITE headquarters in Kizugawa City, Kyoto Prefecture in order to use it as a sustainable building. Through exhibiting at the Expo and subsequent utilization, we addressed various social issues such as reducing carbon dioxide emissions, minimizing waste, and promoting the spread of CLT structures. *1 Technology to reduce CO₂ concentration in the atmosphere by removing CO₂ from the atmosphere *2 Technology to collect emitted CO₂ and store it in the ground *3 Wood-based materials made by layering and bonding the ground sheets so that the fiber directions are orthogonal after arranging them.
