Defining the Pavilion
Two essential questions guided the design process:
What truly defines this pavilion’s identity?
How can it engage with the cultural and technological context of Osaka, Japan, and the global connectivity zone at the Expo?
The answers lie in architectural traditions where geometry and symbolism have always been central. Here, geometry becomes infinite—reflecting plurality, variety, and change. Every element is rooted in timeless architectural principles while opening doors to a universal human experience.

Augmented Reality Meets Tradition
The pavilion is shaped by simple yet complex geometries—the square, symbolizing quantity, and the circle, representing quality, converge through triangular forms. At the heart of the main gallery, an inverted dome with mirrored surfaces is suspended, creating a breathtaking illusion of infinity.
This fusion of parts and whole connects visitors to astronomy, nature, and the sky, offering a spiritual and immersive journey. The mirrors transform perception, allowing visitors to see themselves, others, and endless reflections—an architectural metaphor for unity and universality.

The pavilion doesn’t only celebrate heritage; it also embraces modern technology. Visitors can explore the space through Augmented Reality (AR) on their mobile devices. By scanning QR codes embedded across the pavilion, guests unlock stunning digital visual effects that reveal deeper stories of culture, history, and technology. This merging of physical and virtual worlds creates a one-of-a-kind interactive experience.

Structural Design: A Fusion of Craft and Innovation
At the core of the pavilion is the YOUniversal Gallery, where “You” become “Universal.” Visitors encounter countless reflections of themselves in mirrors above, on water surfaces below, and in the presence of others. It is not just a personal moment but a collective experience, inviting everyone into a shared dialogue of identity, culture, and community.
In today’s fast-paced world, where human connections are often lost, the pavilion offers a symbolic pause point—a place to reconnect with ourselves and with others.

The pavilion’s roof structure explores two approaches:
Waffle Slab System: Inspired by architectural logic, waffle slabs distribute loads to four standing corners, creating both strength and elegance. Wooden lamella pieces are CNC-cut with precise notch connections, ensuring structural coherence.
Steel Frame with Wooden Panels: A hybrid solution where a steel frame supports wooden panels, forming a waffle-like structure that combines durability with beauty.
This combination of engineering innovation and craftsmanship ensures that the pavilion is not only visually striking but also structurally efficient and sustainable.

Landscape and Journey
The architectural journey begins with a carefully designed landscape, shaded pathways, and rooftop experiences. Step by step, visitors are guided toward the central YOUniversal gallery. Every stage is designed to build anticipation, offering moments of reflection, discovery, and wonder.
