Mitsubishi Pavilion (Expo 2025) / Mitsubishi Jisho Design

A "Mother Ship" Hovering Just Above the Ground. – The theme of the Mitsubishi Group pavilion for Expo 2025 Osaka, Kansai—"keeping the world vibrant"—is reflected in the core design concept of life, nature, and human society as interconnected and interacting elements. The pavilion consists of a belowground level and two aboveground levels of layered geometries, beginning with a semi-underground elliptical space. Overlapping this space is a rhombus whose vertices touch the interior curve of the oval. A rectangle similarly laid out within the rhombus provides an additional layer for the structure. Each of these three geometric forms symbolizes a different element—the ellipse, life; the rhombus, nature; and the rectangle, society—while the architecture expresses their mutually supportive relationship. The pavilion has no single front-facing façade; rather, the all-directional design is meant to be visually engaging from both the main plaza on the east gate side as well as the peripheral roads on the opposite side.
