The Hibiya Park Police Box stands as a notable example of contemporary security architecture completed in 1987. Designed by architect Yokogawa Ken, this protective facility represents a thoughtful integration of functional law enforcement operations within Tokyo's prominent public space. Located in the Chiyoda Ward adjacent to Hibiya Park, the structure exemplifies the design principles of its era, balancing accessibility with security requirements. As a fire and disaster prevention facility, it serves both practical and symbolic roles in the urban landscape, reflecting the architect's approach to creating utilitarian structures that complement their surrounding environment while meeting essential community safety needs.
