The Main Pavilion “Grand Ring” of Expo 2025 Osaka: All Nations Standing Under the Same Sky

2025年4月13日，日本大阪迎来一场举世瞩目的盛会——大阪世博会。本届世博会的核心建筑“大屋根”——由日本知名建筑师藤本壮介设计的巨型木制环状廊道，以其独特的设计理念和精湛的木构工艺，不仅获得了吉尼斯“全球最大木造建筑”的认证，更以其深厚的文化内涵和现代创新精神，向世界展示了日本的传统魅力与未来愿景。

On April 13, 2025, Osaka, Japan, hosted the highly anticipated Expo 2025. At the heart of this global event stands the “Grand Ring”, a colossal wooden ring-shaped corridor designed by renowned Japanese architect Sou Fujimoto. The expo’s symbol Grand Ring, also a Guinness World Record holder as the “world’s largest wooden structure”, captivates the world not only with its architectural grandeur but also with its profound cultural significance, embodying Japan’s traditional craftsmanship and forward-looking vision. 

传统工艺的现代表达

A Modern Interpretation of Traditional Craftsmanship  

“大屋根”的设计灵感来源于京都清水寺的木造舞台，采用了日本传统的“贯”工艺。通过柱梁纵横交错的网格状组装方式，建筑既展现了木结构的坚固性，又呈现出优雅的美感。站在“大屋根”下仰望，平缓的曲线与精致的节点清晰可见，仿佛在诉说着日本木构建筑的历史与智慧。这种将古老工艺融入当代建筑的手法，不仅延续了传统，更让历史在现代空间中焕发新生。

The design of the Grand Ring draws inspiration from the wooden stage of Kyoto’s Kiyomizu-dera Temple, incorporating Japan’s ancient “Nuki” joint technique. Its intricate lattice framework, formed by interlocking beams and pillars, showcases both structural resilience and aesthetic elegance. Looking up from beneath the Grand Ring, visitors can admire the gentle curves and meticulously crafted joints—a testament to the timeless artistry of Japanese wooden architecture. By weaving traditional techniques into contemporary design, the structure breathes new life into history while honoring its legacy. 

功能与美学的完美结合

Where Function Meets Beauty  

作为世博会的交通枢纽与灵魂空间，“大屋根”连接了园区内的各个场馆与广场，承担着引导人流的重要功能。其屋顶被设计成一个绿意盎然的“空中花园”，覆盖着丰富的绿植和花卉，为游客提供了远眺濑户内海和俯瞰大阪湾的绝佳视角。在这里，游客可以欣赏到会场、大海与天空交织的壮丽景色，感受自然与人文的和谐共存。

As the expo’s central hub, the Grand Roof seamlessly connects pavilions and plazas, guiding the flow of visitors throughout the site. Its rooftop transforms into a lush “sky garden”, adorned with vibrant greenery and flowers, offering panoramic views of the Seto Inland Sea and Osaka Bay. Here, guests can immerse themselves in a breathtaking landscape where the expo grounds, ocean, and sky converge in perfect harmony.

光影与季节的诗意呈现

A Symphony of Light and Seasons  

“大屋根”还以其独特的光影设计为世博会增添了梦幻色彩。约5000个照明装置和500株带有LED光源的“照明草”分布在屋顶和通道中，从日落到夜间闭场，这些灯光会随着时间的变化调整亮度和色调，呈现出黄昏、入夜和夜间三个时间段的不同氛围。此外，灯光的色调还会随季节更替而变化，让游客在一天或一年的不同时刻都能体验到独特的视觉盛宴。

The Grand Ring enchants visitors with its dynamic illumination. Approximately 5,000 lighting fixtures and 500 LED-embedded “lighting grass” plants adorn the structure, creating a mesmerizing display from sunset until the expo closes at 10 PM. The lights shift in brightness and hue across three phases—twilight, evening, and night—while also reflecting seasonal changes. This ever-evolving spectacle ensures that no two visits are alike, inviting guests to experience the passage of time in a poetic, luminous dance.

和谐与共生的美好愿景

A Symbol of Unity and Shared Skies  

“大屋根”的圆环造型象征着和谐与团结，是对日本历史村落布局的现代化诠释，也寓意着“同处一片天空之下”的美好愿景。这一设计不仅体现了日本文化中对自然与人类共生的追求，也向世界传递了和平与合作的理念。通过这座建筑，大阪世博会希望唤起人们对可持续发展与全球团结的思考。

The circular form of the Grand Ring symbolizes harmony, echoing the layout of Japan’s historic villages while embodying the expo’s theme of “Designing Future Society for Our Lives”. It represents the vision of a world where all nations stand “under the same sky”, united in peace and cooperation. Through its design, the pavilion celebrates humanity’s connection to nature and calls for sustainable coexistence on a global scale.

结语

Conclusion

“大屋根”不仅是2025大阪世博会的标志性建筑，更是传统与现代、自然与人文、历史与未来的完美融合。它以其独特的设计和深刻的内涵，向世界展示了日本的创新精神与文化自信。当游客漫步其中，不仅能感受到木构建筑的魅力，还能体会到人类与自然和谐共处的深远意义。这座建筑无疑将成为世博会最耀眼的明珠，为全球观众留下难忘的记忆。

More than just an architectural marvel, the Grand Ring is a bridge between tradition and innovation, nature and human ingenuity, past and future. It stands as a proud emblem of Japan’s cultural heritage and creative spirit, inviting visitors to explore the beauty of wooden craftsmanship while contemplating the deeper message of harmony between people and the planet. As the crown jewel of Expo 2025 Osaka, the Grand Ring promises to leave an indelible mark on the hearts of all who witness its splendor.
