We created a wayfinding system at the TOTETSU Training Institute, which the client built to develop human resources. For design motif, we used rail lines—the core identity of the client, which continues to thrive in the rail sector. Due to the characteristics of the space, some rooms are in blind areas. The rail-line design marks flow lines to those rooms, offering affordances for spatial movement. To capture theie personality, we also used rail scrap for the facility’s name sign. Through the design, we strove to create a space that would help trainees feel a sense of pride in their work.
