Conceived under Seisho-ji Temple's vision of "spreading Zen worldwide," this international Zen center serves as a multi-purpose hall within Atago Green Hills MORI Tower. The design maintains a minimalist aesthetic, with the entrance steel door finished in traditional hand-lacquered technique. The seamless walls utilize "Otsu-smooth plaster," a traditional Japanese wall-finishing method using natural earth, to create a meditative Zen environment.
