A courtyard where a sense of freedom reigns within its red brick walls

The courtyard within the facility was a place where inmates could envision a connection to the outside world. Hiroki Hasegawa of Studio Onsite, who designed the garden, referred to it as the "outside within," expressing a yearning for the world beyond.

A Courtyard Sensing the Outside

Architect Hiroki Hasegawa of Onsite Climate Design pursued a concept contrasting with the imposing red-brick walls: "a landscape that could never have existed in a prison." Once an "inside-out" courtyard where inmates yearned for the outside, it is now a modern sanctuary. The contrast is vivid—indoor tension versus outdoor light, and liberation within towering walls.

A Path Through the Seasons

Breathing vibrant life into grand architecture of national prestige, trees and flora take center stage. Pathways are designed in a zigzag pattern to encourage mindful wandering, with chairs and tables inviting guests to pause and feel the changing seasons. Harmonizing with history, this courtyard features thoughtful plantings that celebrate a revolving canvas of spring blossoms and autumn hues.

A Courtyard Emerging in Light

At dusk, the courtyard transforms, revealing a mystical character. Mr. Hasegawa envisioned a space that does not sink into the night, but "emerges" within the light. Soft illumination brushes pathways, seating, and flora, bringing three-dimensional silhouettes to life. This design beautifully reframes the grim image of prison architecture, enhancing the view from the lounge and evening strolls.
