Expo 2025 Osaka

A rest area where clusters of trees leading into a quiet forest are interwoven with small yet unique man-made structures. The entire site also serves as a dining space, with food trucks and tables arranged throughout, drawing many visitors in search of shade. However, alongside accessible facilities such as restrooms, an information center, and lounges, there are also many restricted-use spaces including a first-aid station, a police booth, and a telecommunications equipment room.

"Map the New World" is the motto of Project PLATEAU, led by Japan's Ministry of Land, Infrastructure, Transport and Tourism (MLIT), to develop and expand access to 3D models representing the diversity of cities across the country. Japan comprises a total of 744 cities, including 14 with populations exceeding one million, 190 with between 100,000 and one million inhabitants, and 540 with populations between 10,000 and 100,000. To date, 3D models of more than 250 cities have been made available as open data through the country's public G-Spatial Information Center, and can also be accessed via an online browser viewer. According to public authorities, the project aims to strengthen urban resilience by providing society with new tools to address local challenges. This involves not only urban space modeling but also collaboration with local governments, private companies, and technology communities. The project also includes a digital reconstruction of the recently closed Osaka World Expo site.

Architecture of the Earth. Yumeshima, the site of the Expo, is a reclaimed island with inherently weak ground conditions. As a prerequisite for construction, a volume of soil equivalent to the weight of the proposed building had to be removed from the site.

​​A Gothic cathedral can take centuries to complete. A world exposition pavilion may stand for six months. A ritual structure in Kolkata rises and vanishes within five days. Yet each draws pilgrimage, shapes collective memory, and reorganizes urban life. If heritage has long been defined by what endures, architecture repeatedly shows that cultural authority can also belong to what gathers people.

Exhibitions can be an opportunity to extend architectural discourse beyond professional circles, opening conversations with broader publics and serving as an interface between architecture and society. Within this concept, major international events such as the Osaka International Expo 2025 and the Venice Architecture Biennale have adopted the idea of the circular economy as one of their organizational objectives. The idea of circularity in events can be reflected in, for example, their energy consumption, the impact of the displacement they generate, their waste, or the useful life of their infrastructure. The site destined for the last World Expo, held in Osaka from 13 April to 13 October 2025, was surrounded by a massive timber structure designed by Sou Fujimoto Architects, one of the world's largest wooden constructions. The Japan Association for the 2025 World Exposition committed to reusing building materials "as much as possible," with concrete plans for their reuse to be finalized by March. In the meantime, some relocation alternatives are already emerging for the pieces of the World Expo structure.

Rising from the ground as a cultivated landscape of learning, the Uzbekistan Pavilion "Garden of Knowledge" at Expo 2025 Osaka translates national transformation into a spatial and material narrative.

The 2025 Osaka Expo has captured widespread attention—not only for its architectural ambition and spectacle, but also for breaking records and generating controversy. Its most iconic feature, a monumental timber ring designed by Sou Fujimoto, has already made headlines as a Guinness World Record-breaking wooden structure. Built on the reclaimed island of Yumeshima, the site has attracted praise and critique in equal measure.  Beyond its awe-inspiring 2-kilometer circumference—parts of which extend dramatically over the water—the structure has also drawn concerns, including questions about health & safety, extreme heat, and swarms of insects that may affect the visitor experience.

In a global landscape marked by accelerated change, 2025 emerged as a decisive year for architecture—not only because of the major events that animated the international circuit, but above all because of the voices that stood out within them. From the Venice Architecture Biennale to Expo Osaka, pavilions and installations from the Global South ceased to function as mere exhibition gestures and instead asserted themselves as territories of memory, resistance, and imagination, articulating narratives that expand the horizons of contemporary architectural debate.

This past year marked a period of introspection for architecture. As 2025 unfolded, the discipline, confronted with evolving environmental and social realities, entered a broader turning point in how it understands its role and how users engage with it. Throughout the year, exhibitions shifted focus away from buildings as isolated objects toward a broader understanding of relationships between ecology, equity, everyday life, and collective imaginaries. Across institutions and cities, they operated less as showcases and more as discursive platforms: places where architecture was not only presented, but also imagined, questioned, and collectively redefined. 

This week's architecture news highlights a diverse global landscape of design innovation, cultural investment, and adaptive reuse. Across continents, new museums and cultural venues are opening to foster dialogue around art, design, and community engagement. At the same time, major recognitions and project announcements underscore the growing importance of sustainable, socially conscious practices in shaping contemporary architecture. From adaptive transformations in New York, Tainan, and Milan, including preparations for the Milano Cortina 2026 Winter Games, to new cultural landmarks in Ghana and Qatar, this week's overview features projects by leading firms such as Herzog & de Meuron, Snøhetta, and Mecanoo, alongside initiatives from emerging practices like Limbo Accra in West Africa.

About a month after the closing of Expo 2025 Osaka, the designs and constructions presented at the world's fair remain as a legacy. While the Bahrain Pavilion, designed by Lina Ghotmeh Architecture, drew particular attention this year for receiving double recognition, it was one among many awarded projects. During the awards ceremony held on the penultimate night of the event, a total of 45 awards were presented among 165 participating countries. The Official Participant Awards are granted according to pavilion size and type, recognizing excellence in Architecture and Landscape (for self-built pavilions only), External Design (for module pavilions only), Exhibition Design, Theme Development, and Sustainability. The recipients were selected by an international jury of nine experts who visited all national and thematic pavilions during two evaluation sessions in May and October 2025. The following overview presents all 45 pavilions distinguished in the five categories of the Official Participant Awards.

Cultural diplomacy refers to the use of cultural expression and creative exchange to foster understanding and build relationships between nations. In this context, architecture has long played a distinctive role. Beyond its functional and aesthetic dimensions, it serves as a medium of communication, a language through which countries express identity, values, and ambition on the global stage.

This project is a public restroom for the EXPO 2025. In response to the context of a plaza surrounded by iconic architectural landmarks, this structure was conceived not as a clearly defined form, but as something that recedes into the background—an architecture that allows only the phenomena of its surroundings to come into focus.

This week in architecture, global recognitions and new unveilings underscored the field's growing commitment to climate awareness, cultural continuity, and adaptive reuse. From Expo 2025 Osaka's closing ceremonies to international award announcements, the focus turned to architects and designers redefining the relationship between place, material, and community. Alongside these recognitions, major new projects, from Dubai to California, illustrated how design continues to evolve across scales: shaping cities, preserving heritage, and addressing urgent global challenges through context-driven architecture.

Bahrain's architectural participations in the international exhibitions have gained increasing global recognition, marked most recently by major awards at Expo 2025 Osaka and the Venice Architecture Biennale. These milestones reflect a broader trajectory in which the country's design culture, rooted in climatic intelligence and cultural continuity, has become a prominent voice in international conversations on context-driven architecture.

Monday, October 13th, marked the conclusion of Expo Osaka 2025. The exhibition gathered representatives from 165 countries and international organizations and welcomed around 28 million visitors to Yumeshima, a reclaimed site in Osaka Bay. The site was reimagined through a masterplan and bounded by a Guinness World Record-breaking wooden circular structure, both designed by Sou Fujimoto Architects. Over 184 days, participants were able to visit the self-built, modular, and shared pavilions, national exhibitions, and public activities organized under the overarching theme "Designing Future Society for Our Lives." During its six-month run, the Expo set out to explore three pivotal subthemes, Saving Lives, Empowering Lives, and Connecting Lives, as an invitation to bring together new perspectives for our built and social ecosystem.

The Kingdom of Bahrain's Pavilion at Expo 2025 Osaka, designed by Lina Ghotmeh – Architecture, titled "Connecting Seas," has been awarded the Gold Award for Best Architecture and Landscape in the self-built pavilions under 1,500 square meters category. Presented by the Bureau International des Expositions (BIE), the award recognizes architectural excellence in spatial design, creativity, and sustainability. The announcement was made at an official award ceremony in Osaka, Japan, attended by commissioners general and representatives from participating nations. Commissioned by the Bahrain Authority for Culture and Antiquities (BACA), this marks the country's fourth participation in a World Expo and reflects an ongoing commitment to expressing national identity through architecture and cultural dialogue.

Uzbekistan's architectural and artistic heritage reflects a layered history shaped by centuries of cultural exchange along the Silk Road. From the monumental ensembles of Samarkand and Bukhara to the scientific and educational institutions of the Timurid era, architecture has long been a vessel of identity and knowledge across the region. In the twentieth century, Tashkent emerged as a new urban laboratory, where modernist ideals met local craft traditions and environmental pragmatism. The city's reconstruction following the 1966 earthquake became a defining moment, fusing Soviet urbanism with regional aesthetics to produce a distinctly Central Asian expression of modernity, one that translated cultural continuity into concrete, glass, and light.
