rinkans

Rinkans are a type of residential building primarily found in Japan, characterized by their long, narrow floor plan and multiple stories. The term "rinkan" (狭間, literally "between spaces" or "gap") refers to the distinctive architectural feature of these buildings, which are typically constructed on narrow plots of land, often sandwiched between other structures. This constraint on space dictates their vertical orientation and elongated shape.

The design of a rinkan often includes a series of rooms or units arranged along a central corridor or staircase. This allows for efficient use of limited space and can create a sense of communal living, though individual units are usually self-contained. The narrowness of the buildings can also influence natural light penetration, leading to design considerations like skylights or open courtyards to improve illumination and ventilation.

Historically, rinkans emerged as a practical solution to urban land scarcity, particularly in densely populated cities. They are commonly found in older districts and can range from simple, older constructions to more modern, renovated residential spaces. While they may appear similar to other multi-story dwellings, the defining characteristic of a rinkan is its extreme narrowness in relation to its length and height, a direct consequence of the building's site limitations. The aesthetic and functional aspects of rinkans are deeply tied to the challenges and opportunities presented by tight urban environments.
