The Totetsu Kogyo Co., Ltd. construction company was founded at the request of the former Ministry of Railways to maintain and reinforce Japan’s rail system. The design team created a wayfinding system for the company’s building, using the motif of rail lines. Rooms in low-traffic areas or those accessed through narrow corridors are less likely to be recognized by users. People can use the rail-line design to easily find their destination, changing inactive space into active space. Through the design, the design team not only strove to facilitate movement through the building but also create an environment that would help trainees feel a sense of pride in their work.
