Expo Kansai Osaka 2025, with the theme "Building a Future Society, Imagining a Future Life", will open on April 13, 2025. 150 countries and international organizations are expected to participate, and more than 20 million visitors are expected to visit the Expo.

Sou Fujimoto is the chief designer of Expo 2025. The pavilion is connected to the national pavilions by a circular walkway with a circumference of 2 km, which can keep out rain and sunlight. On the roof of the cloister, visitors can look out over the sea amid the flowers.

Fujimoto said he hoped the design, which will be the largest wooden structure in the world, would add luster to the Expo.

The highest point of the cloister is 20 meters high, with an inner diameter of 615 meters and a width of 30 meters. An estimated 20,000 cubic meters of wood will be sourced from both Japan and other countries, resulting in a Japanese-style wooden structure with columns and beams crisscrossed.

The theme also aims to promote cocreation by the international community to design a sustainable society that supports individuals' ideas about the way they want to live. In other words, the Expo will for the first time ask the question bluntly: "What is a happy way of life?" . The Expo is being held at a time when new social challenges are emerging, such as widening economic disparities and intensifying conflicts, as well as advances in science and technology, such as artificial intelligence and biotechnology, that will bring changes to humanity, such as extending life spans. Saving lives, empowering lives and connecting lives are the three major themes of the Expo.

China Pavilion

Design: China Academy of Architectural Design

The architectural design of the China Pavilion takes "Chinese ShuJian" as inspiration. The exterior of the building is shaped from the long scroll of traditional Chinese books. Through the three main elements of bamboo, Chinese characters and scrolls, it demonstrates the spiritual symbol and cultural essence of the Chinese civilization, which is "The Tao of nature, the unity of nature and man", and interprets the core concept of China's unswerving pursuit of green development in the new era.

The building's elaborate facades are inscribed with poems and poems, depicting the landscape artistic conception, which is integrated with the bamboo shadow garden landscape in the ink pool in front of the museum, bringing unique visiting experience to the audience.

Bamboo is a representative element of Chinese civilization. Chinese people love bamboo, grow bamboo. At the same time, bamboo is also a renewable ecological building material, which reflects the value orientation of harmonious coexistence between human and nature and the development direction of contemporary architectural technology.

Chinese characters are the cultural treasure of the Chinese nation and one of the oldest existing characters in the world. No matter the poems and poems, or the Zhencao script script, they are all spreading the rich information and unique charm of Chinese civilization to the world.

The scroll is an inexhaustible treasure house of thoughts, which demonstrates China's cultural soft power of "looking at humanity to transform itself into the world" and embodies the profound and enduring cultural confidence of the Chinese nation.

Swiss pavilion

Design: PARTNER Manuel Herz ArchitectsBELLPRAT

The concept of the Swiss Pavilion focuses on sustainability. Spheres and modular structures made from recycled and recyclable materials, as well as plants that overgrow around the building, seal in and sequester carbon dioxide, constitute a single storey accessible building and help to minimize the ecological footprint. The scenery occupies the light exterior of the building and shows the contents of the exhibition in light and color.

In the pavilion's five spheres, visitors experience how Swiss innovation has been created from the nutrients of nature, as well as Swiss cultural traditions and a bit of magic. They can help shape and explore exhibitions themselves, and ultimately bring the innovative power of Switzerland to the world in the form of plant seeds.

Czech Pavilion

Design by Apropos Architects

Dubbed "Sculptural Vitality", the 2,121-square-metre building uses a spiral form to evoke dynamic spiraling upward motion and is considered an allegory of the ideal life path. The concept of architecture is based on the thesis that space is shaped by the movement of body and soul. Through the visitors' active activities inside the pavilion, the cultural content is materialized, thus completing the visitors' journey -- gaining internal vitality.

The pavilion aims to explicitly encourage visitors to engage in some form of physical exercise, while the content forces creative engagement with spiritual and cultural values.

German pavilion

Design: LAVA -- Visionary Architecture Laboratory

The 3,500-square-meter pavilion, titled "Wow! Germany ". The design and concept of the German Pavilion is based on the theme of circulation and will provide visitors with a multi-sensory journey about the circular future society.

The roundness is also reflected in the buildings, which are round, made of wood and surrounded by greenery. All materials are reusable, and the steel structure and trees are rented, which will be returned to the local nursery after the Expo. There is no doubt about the importance of climate-friendly buildings: the construction sector accounts for nearly 40% of global CO 2 emissions.
