三菱集团为2025年大阪世博会打造的展馆，其主题为“让世界保持活力”，这一理念体现在将生命、自然与人类社会视为相互关联的有机整体。

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.

展馆由一个地下层和两个地上层构成。建筑以几何形态叠合排列，从半地下的椭圆形空间开始，其上叠加一个菱形，该菱形的顶点触及椭圆内部的曲线；在菱形内又以类似方式布局了一个矩形，为结构增添了额外的层次。这三种几何形态分别象征着不同的元素——椭圆代表生命，菱形代表自然，矩形代表社会——建筑则表达了它们之间的相互关系。展馆并未设置单一主立面，这种“全向性”的设计使其无论是从东门主广场，还是从对侧周边道路一侧，均能呈现出引人注目的视觉效果。

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.

内部空间的设计能够让参观者在穿越展馆的主体时有立体的感受，并在以主视频展览为中心的各个区域中体验丰富多彩的活动。参观者到达后，首先下行至被称为“等待公园”（Waiting Park）的半地下空间。此处的设计既阻隔了阳光直射，又促进了冷空气流通，从而为参观者营造出一个阴凉舒适的等候区域。随后，参观者前往一层的预展区（Pre-Show）观看导览视频，再到二层的主展区（Main Show）。在沉浸式视频体验结束后，参观者途经一楼的尾展区（Post-Show），最终到达结构尖端处的“三角公园”（Sankaku Park），感受悬浮于半空的空间张力。

The interior space is designed to allow visitors to three-dimensionally cross the “body” of the pavilion while engaging in various experiences throughout areas centered around the main video exhibition. Upon arrival, visitors first descend into the semi-underground space known as the Waiting Park. The design blocks direct sunlight from entering the space and facilitates the flow of cool air. The result is a shaded and comfortable waiting area that all visitors can enjoy. From there, visitors proceed to the Pre-Show on the first level to view an orientation video before moving on to the Main Show on the second level. After an immersive video experience, visitors return to the first floor and pass through the Post-Show area before reaching an area at the structure’s tip called Sankaku Park (lit., Triangle Park), which feels as if it is suspended in midair.

展馆的主要设计概念是对小规模资源的可循环利用。展馆将在为期六个月的世博会结束后拆除，场地也将恢复至原始状态。设计最大限度地减少了建筑与地面之间的直接接触，以确保珍贵的土壤资源在世博会结束后，能以最小的环境影响回归自然状态。开挖出的土壤将被重新用于场地复垦，这是我们在资源循环利用方面的承诺。

A key concept that inspired our design for the pavilion was the circular use of resources on a small scale. The pavilion will be dismantled after the six-month duration of the Expo, and the site will be restored to its original state. The design minimizes direct contact between the building and the ground to ensure that the soil—a precious resource—is restored to its natural condition with minimal environmental impact after the Expo ends. The excavated soil will be repurposed for site reclamation, fulfilling our commitment to circular use.

在饰面材料的选择上，我们探索了通常仅在施工阶段使用的临时材料的另类用途，将其重新构想为主要的饰面材料。考虑到这些材料在世博会结束后的再利用潜力，我们希望降低展馆的经济与环境成本。具体来说，展馆外立面采用了聚碳酸酯板与钢结构脚手架1:1组合的方式。展馆中所使用的沙袋、钢管（单管脚手架）、踏板、照明装置、风扇等材料均可就地重新利用。此外，蓝色防水布、吊顶框架材料、胶合木、欧松板（OSB），以及链网围栏等实用材料也巧妙地融入了饰面和内部设计中。

For the finishes, we explored alternative uses for temporary materials that are typically employed only during construction, reimagining them as primary finishing materials. By considering the potential for these materials to be repurposed after the Expo, we aimed to reduce both the economic and environmental impact of the pavilion. Specifically, the pavilion’s exterior is covered with an equal combination of polycarbonate panels and steel construction scaffolding. Sandbags, steel pipes (single-tube scaffolding), tread plates, lighting fixtures, fans, and other materials used in the pavilion can all be repurposed on-site. Additionally, practical materials such as blue tarps, ceiling framing materials, laminated timber, oriented strand board (OSB), and chain mesh fencing are cleverly incorporated into the finishes and interior design.

空调区域被尽可能最小化，主要的室内空间被设计为一个半室外的区域，类似于日本传统住宅中的走廊空间（缘侧，engawa），从而降低了制冷负荷。设计同样避免采用过于复杂、戏剧化的照明，而是让建筑内部光线自然向外渗透，形成渐变光影。这种温柔、细腻的照明，既传承了植根于日本文化传统的幽暗美学理念，又为空间注入了深度与层次感。

The air-conditioned areas were minimized, and the majority of the interior space was designed as a semi-outdoor area reminiscent of the veranda space (engawa) found in traditional Japanese houses, thereby reducing the cooling load. The design also eschews overly complex or theatrical lighting; rather, soft illumination from within the building spills outward, creating a gradient of light and shadow. Such gentle, nuanced lighting honors the aesthetic concept of darkness rooted in Japanese cultural traditions while also imbuing the space with a sense of depth and richness.

三菱未来馆的设计代表了对可持续发展的承诺。从降低能耗到材料再利用，从建设到拆除全生命周期，展馆各个方面均力图打造一个小规模资源可循环利用的建筑样本。

The pavilion's design represents a commitment to sustainability, with every aspect— from minimizing energy consumption to reusing materials—aiming to create a small-scale circular architecture from construction to demolition.
