A growing trend in Japan sees spaces dedicated to blocking out sensory input, such as light and sound. Often in urban and high-stress environments, these spaces are becoming increasingly popular as means for relaxation and stress relief. Residents turn to these areas for finding serenity amidst the bustling city life. The concept is backed by various wellness and therapy experts, citing the numerous benefits of lengthy periods without sensory stimulation.

Japanese society, especially in large cities, is often characterized by long working hours and densely populated areas, which can increase stress and sensory overload. Thus, a respite from sensory stimuli aligns with the ongoing pursuits for better mental health and work-life balance in Japan. These spaces may also serve as an individual's solution to Japan's inherent societal adherence to communal harmony, allowing them to retreat and refresh without causing disturbance to others.

In the US or EU, similar solutions may be available, albeit commonly marketed under wellness trends such as sensory deprivation tanks or meditation centres. The rise of "quiet" or "sensory-free" spaces in public and work areas is not as pronounced. This difference may reflect variations in societal pressures and distinct approaches to stress management and mental health wellness.
