Wearable device for sleep: Carry Your Rest Anywhere
As digital connectivity exposes us to an overwhelming stream of information, sleep remains the only time we can truly disconnect from the world. By combining cutting-edge technology with traditional wisdom, we introduce an innovative sleep system—seamlessly integrating rest into the closest thing to the body: clothing.
Issue
Japan Faces a Sleep Deprivation Crisis
Among 33 developed nations, Japan ranks lowest in average sleep duration.* Chronic sleep deprivation continues to be a serious issue, resulting in immeasurable economic loss.

Creation
Merging Technology and Tradition
We created next-generation sleepwear designed to optimize the timing of short naps . Equipped with biometric monitoring, the sleepwear system uses sound and lighting to enhance both sleep and wakefulness. Inspired by the traditional Japanese “Yogi”—a quilted kimono used for warmth—it is reimagined for modern sleep environments, balancing comfort and portability. The inner lining incorporates Kodenshi fiber, promoting deep relaxation.






Technology
A Personalized Sleep Environment
By analyzing biometric data from a smart ring, the system dynamically adjusts music and lighting to enhance sleep quality. Stress levels dictate two types of optimized sound frequencies for easier relaxation. A red-toned light fosters deep sleep, while a gentle blue glow and carefully curated music facilitate a smooth awakening.
Future
Expanding Co-Creation Partnerships
The ZZZN SLEEP APPAREL SYSTEM is an open innovation project, actively seeking collaboration with apparel brands, material manufacturers, pattern makers, and designers. By bringing together specialists from various fields, we continue to explore the intersection of sleep, fashion, and sound, shaping the future of rest through wearable solutions.
