Expo 2025 in Osaka, Japan, promised a grand vision of the future — a showcase of innovation, technology, and culture. Having attended the event, I was able to experience it firsthand, as well as the challenges that come with such a massive gathering. From the moment I entered, the scale and ambition of Expo 2025 were evident. The organizers clearly put a great deal of effort into architectural design and visual presentation, creating spaces that were both immersive and inspiring. It felt like stepping into a miniature city of the future, a space carefully curated to inspire imagination and wonder. The event brought together over 200 participating countries and organizations, showcasing their innovations and cultures across an area of approximately 155 hectares — roughly the size of a small city. The main theme of Expo 2025 was “Designing Future Societies for Our Lives,” focusing on sustainability, technology, and global collaboration. Visitors had the opportunity to explore advances in areas such as artificial intelligence, renewable energy, biotechnology, and many other innovations shaping the future of humanity.
One of the aspects that truly stood out was the overall design of the Expo grounds. The layout of the pavilions, wide walkways, and open plazas created a sense of order and flow, even amidst the crowds. The architectural styles were diverse and visually striking, reflecting both futuristic visions and cultural identity. Thoughtful landscaping, color schemes, and integration of natural elements made walking through the Expo an immersive experience. The attention to design extended beyond individual pavilions, shaping the entire environment into a cohesive, inspiring urban landscape that felt like a glimpse into how the cities of the future might combine aesthetics, functionality, and cultural expression.
At the heart of the Expo stood the Grand Ring — the largest wooden architectural structure on Earth, a two-kilometre-long circular walkway that gracefully framed the site. Walking along it felt remarkably serene, elevated above the busy grounds, it created a sense of tranquility and connection to nature within an urban setting and offered breathtaking panoramic views of the entire Expo landscape.
Some national pavilions provided particularly immersive experiences. They combined design, culture, and sensory engagement in ways that made visitors feel connected to distant parts of the world. Many countries embraced a sustainable approach in the design of their pavilions, using recyclable and environmentally low-impact materials. A variety of wooden structures and innovative materials emphasized some key ideas like lightness, transparency, circularity and vernacular elements, which were thoughtfully reflected in the main architectural forms, ornamentation, and material choices. Many of the structures will be easily disassembled after the event and some even have plans of being relocated, like the Colombian pavilion, for example. The overall landscape of the Expo site, in many ways, complements the ideas of critical regionalism by highlighting the contrast between contextually sensitive designs and those that feel detached from their surroundings. The coexistence of culturally grounded pavilions alongside overtly global or out-of-context structures underscored the ongoing tension between local identity and universal modernity in contemporary architecture. The Nordic Circle pavilion, jointly created by Denmark, Finland, Iceland, Norway, and Sweden, stood out as a powerful example of architecture with a distinct vernacular character, reflecting the shared cultural and environmental values of the Nordic region.
Among the thematic spaces of Expo 2025, the Future City Pavilion stood out as a central exploration of how technology and innovation might shape the way we live in the decades to come. The pavilion explored speculative visions of urban life through immersive installations and participatory experiences, it presented utopian scenarios of enhanced human capability and harmonious coexistence between people, nature, and machines. While the ideas were conceptually ambitious – imagining cities driven by artificial intelligence and bio-integrated design – many of them still felt distant from present reality. The pavilion ultimately invited reflection on how technological optimism must be balanced with ethical and social awareness in shaping the cities of the future.
Beyond their architectural forms, many pavilions also offered rich interior experiences that reflected each nation’s culture through exhibitions, gastronomy, and design. At the Colombian pavilion, for instance, it was possible to touch materials typical to the country, smell and taste local coffee, and learn about its unique flora and fauna. The Spanish pavilion offered a similar blend of sensory experiences, with spaces to enjoy traditional food and explore cultural elements in a highly engaging environment. These pavilions reminded me that Expo 2025 was not only about technology and architecture — it was also about human creativity and cultural storytelling.
The Expo’s impact on architecture is profound, as it has long served as a platform for experimenting with bold, visionary designs — introducing new construction materials, sustainable techniques, and spatial concepts that have influenced urban planning and architectural innovation worldwide. Despite the inspiring design and ambitious vision, the practical realities of hosting such an enormous event were impossible to ignore. With up to 200,000 visitors per day, movement through the grounds often became extremely difficult. Lines for entering the Expo itself, as well as individual pavilions, could stretch for hours, sometimes under scorching sun or during sudden thunderstorms. Access to food and seating was limited; in some cases, waiting for a restaurant table took longer than visiting a pavilion. Many people resorted to sitting on the ground with blankets or foldable chairs, clearly anticipating the long, crowded day ahead. Even though Japan is renowned for its organization and safety, there were moments when the density of the crowd created stressful and potentially dangerous situations, with people feeling faint or trapped in the flow of visitors.
These experiences brought up a deeper reflection for me. Expo 2025 was designed to showcase ideas for the future of cities and societies, including solutions for mobility, urban planning, and public engagement. Yet, the realities of overcrowding, long waits, and limited access to basic necessities like food and shade highlighted a stark contrast between the conceptual vision and its practical implementation. If the goal is to demonstrate how future urban spaces could be organized efficiently and safely for citizens, experiencing these issues firsthand was both surprising and concerning. It was a reminder that designing the future must account for human behavior, comfort, and safety, especially in dense, high-traffic environments. After all, one of the main goals of architecture and urban planning has always been creating functional, comfortable and safe spaces. It felt almost paradoxical to encounter some of the very challenges we face in today’s urban environments at an event intended to envision the cities of the future.
Looking back, attending Expo 2025 felt like a complex, multi-layered experience. On one hand, it was inspiring – a showcase of human imagination, cultural diversity, and potential technological innovation. On the other hand, it was a real-world reminder of the practical challenges of managing large urban populations, especially in temporary, high-density settings. The contrast between the visionary ideas for future cities and the immediate difficulties of crowd management was striking, making me think about the broader responsibilities involved in urban planning and large-scale public events. For a single day, I could endure the crowds and heat, but the experience highlighted the importance of safety, comfort, and accessibility when imagining and building the cities of tomorrow. Expo 2025 was, in every sense, a blend of inspiration and reality, showing both the promise of human creativity and the challenges of making that promise tangible for everyone.
