Stora Enso and Czech Pavilion partner at World Expo in Japan

The World Expo serves as a global platform that unites people and innovations from around the world to tackle challenges facing humanity on an international scale. This year Stora Enso is proud to be a part of the event that welcomes tens of millions of visitors in Osaka, Japan as a partner of the Czech National Pavilion. Over 800 m³ of Sylva™ CLT elements are being used for the ground-breaking PEFC-certified wood structure of the pavilion with a glazed façade aimed to inspire the world with its innovative use of materials.

“Our partnership with the Czech National Pavilion gives us a unique opportunity to present one of the tallest cross laminated timber (CLT) buildings in Japan on the largest stage of global innovation, here at the World Expo at Osaka. Stora Enso already has a long history of supplying high quality posts and beams and sawn wood to Japan. Thanks to CLT´s leading sustainable performance, its well-being benefits for the tenants and last but not least, its improving financial competitiveness we see an increasing demand for wooden commercial and multi-storey residential buildings in the region. I am sure the pavilion will serve as a stunning example of the unique structures that can be built using Sylva™ by Stora Enso kit of prefabricated wood-based products for low-carbon buildings,” says Lars Völkel, Executive Vice President, Stora Enso Wood Products division. 

Japan’s deep-rooted tradition of wooden architecture—exemplified by the Horyu-ji Temple from 607 AD, the world’s oldest surviving wooden building—continues to evolve today. “The Japanese government actively promotes timber use in construction, including non-residential buildings, to cut carbon emissions and support a circular economy. This aligns with Stora Enso’s mission to do good for people and the planet by replacing non-renewable materials with renewable products,” says Satoshi Yamada, Sales Director Japan, Wood Products, Stora Enso. 

Welcoming visitors until October 

The eye-catching Czech National Pavilion occupies a prominent oceanfront location, offering visitors a truly immersive experience. Its standout position next to the water makes it one of the most visually striking structures at the Expo.  

A 260-meter-long educational trail winds through the site, providing stunning views of Osaka Bay. At its heart is a multifunctional auditorium that will host a rich and engaging program throughout the exhibition, making it a hub for learning and cultural exchange. 

Inside, the pavilion features a dynamic 402 m² exhibition space, with widths ranging from 1.8 to 7 meters and soaring up to 12 meters in height. The design highlights both architectural innovation and sustainable construction, brought to life through Stora Enso’s Sylva™ CLT elements made in Czechia with wood from sustainable managed local forests. 

Construction began in mid-September 2024, and by mid-December, the main structure was completed. This was followed by the installation of the pavilion’s signature glazed spiral, adding a modern and elegant finishing touch. 

The World Expo in Osaka will be open from 13 April to 13 October 2025. The Czech National Pavilion is a must-visit for anyone passionate about architecture, engineered wood, and environmental stewardship.
