FUKURACIA OAZO is a meeting room rental space in a high-rise building in Marunouchi, Tokyo. The area is the business center in Japan surrounded by new buildings. Instead of just following the usual trends in the developed Marunouchi area, we created this space in pursuit of the Japanese spirit of finding beauty in the passage of time in a day. We focused on changing light and colors to reflect daily and seasonal changes in the space. The dyed aluminum panel “SORA NO ENGAWA” at the wide windows varies its hues, reflecting abundant tones of traditional Japanese colors such as Ruri, Gunjo, and Ai.
