“Toward a future starting from the forest. “Sumitomo Pavilion””
The design of the Sumitomo Pavilion is inspired by the “peaks of the Besshi Mountains” in Shikoku, Japan
where the foundation of Sumitomoʼs growth was established; and features a silhouette of its mountain ranges.
The Pavilion is built with the trees of the “Sumitomo Forest”, which has lived through more than 400 years of
Sumitomo history. The lumber is processed into “plywood” based on the concept of “valuing each life, one tree
at a time” and ensuring that the tree is used in its entirety. Furthermore, the leftover “peeling core” from peelingthe logs will be turned into benches to be set up throughout the space.

The pavilion will make effective use of wood resources while also recycling to balance both ecology andeconomy and ultimately creating a building that offers the warmth and healing powers of wood. We will proceedwith preparations in our aim to build a pavilion that will portray our hopes for the future and captivate the heartsof many.
There are less than 500 days to the opening of Expo 2025 Osaka, Kansai. The Sumitomo Group will gather thewisdom, technology, and talent garnered to present and address social issues through the collective powers ofthe group. We will showcase exhibitions that move peopleʼs hearts, promote change, and create hope for thefuture; along with aspirational entertainment to create a place where people can gather and start conversations.
