Press Kit
- Unique Properties
- Planned international school campus in Yokohama, Kanagawa (design 2023-2025, unbuilt). A rice-terrace-inspired section steps upward from north to south to satisfy strict shadow control, while stacking green roof terraces as everyday learning landscapes. A central skylight and atrium bring daylight deep into the long plan, and transparent classroom fronts promote curiosity and cross-cultural interaction. Site approx. 11,300 sqm; total construction floor area approx. 29,000 sqm.
- Dimensions & Packaging
- Planned campus: B2F + 5F; building height approx. 19.5 m. Typical floor height 3.9 m (1F-5F); ceiling height 3.0 m (1F-5F, B1) and 4.0 m (B2); floor height 4.4 m (B1) and 6.1 m (B2). Total construction floor area approx. 29,000 sqm on a site approx. 11,300 sqm. Key devices: stepped massing for shadow control, green roof terraces, central skylight and atrium, transparent classroom fronts.

- Production Technology
- Realized through section, not a decorative skin. Terraces and roofs are layered as planted open spaces, forming a continuous learning landscape. A large skylight spans the center of the elongated volume, and an open atrium increases daylight penetration and visual connection between floors. Classroom fronts use glass partitions to keep learning visible and inviting while maintaining controlled separation.
- Design Challenge
- Challenge: create an internationally open learning environment while conveying Japanese culture without turning tradition into decoration, and also satisfy strict shadow control. The solution turns compliance into identity: a rice-terrace-inspired mass steps upward from north to south and layers green roof terraces as everyday learning landscapes. Inside, a large skylight and atrium secure daylight and orientation, while transparent classroom fronts keep learning visible and interactive.
- Research
- Type: design research. Objective: translate rice-terrace heritage into an educational campus that meets strict shadow control while providing biophilic learning space. Method: iterative north-to-south sectional studies; stacking green roof terraces; daylight strategy using a central skylight and atrium across an elongated plan; transparency via glass classroom fronts. Tools/Data: compliance and daylight checks. Result: a campus where cultural identity is experienced as daily landscape and light, supported by bright shared interiors and accessible terraces.
- Inspiration
- Inspired by rice terraces, a Japanese landscape shaped by slope, water, and time. The campus translates this heritage into an urban school: overlapping green roof terraces form a daily outdoor learning terrain, while the stepped section rising north to south responds rationally to strict shadow control. The concept lets international students sense Japanese culture through routine movement, light, and landscape, not as decoration.
- Project Duration
- Location: Yokohama, Kanagawa Prefecture, Japan. Design period: 2023-2025. Project status: unbuilt, construction not scheduled. The proposal forms a stepped, rice-terrace-like campus mass shaped by strict shadow control, with layered green roof terraces and a central skylight/atrium for daylight quality. Site approx. 11,300 sqm; total construction floor area approx. 29,000 sqm.
- Operation Flow
- The campus works as a vertical landscape. Students move along layered terraces and corridors around a central atrium, keeping orientation in the long plan. The skylight and atrium make shared spaces bright and legible, while green roof terraces support daily outdoor learning and rest. Glass-partitioned classrooms keep activities visible, encouraging curiosity, spontaneous encounters, and cross-cultural exchange.
