We ask ourselves: “What matters most to those who pass through this door?” “Where are they headed, and in which direction will their journey unfold?” Our mission goes beyond functionality—we maximize cross-departmental collaboration to propose the very nature of space, starting from the door itself. For example, we engage in proposal-based sales activities that include flow line planning, offering high-quality products with outstanding cost performance. Our robust international sales and service network ensures meticulous and reliable maintenance. Together, these elements contribute to creating comfortable and meaningful spaces for our customers. Looking ahead, we will focus on developing barrier-free products in anticipation of an aging society, expanding the comfort and accessibility of door spaces across a wider range of environments.
