Societal Issues We Aim to Solve

The Company is developing its business with the aim of solving the societal issue of "significant economic loss due to sleep deprivation." According to a 2016 study published by the American think tank RAND Corporation, Japan's economic loss due to sleep deprivation is estimated to be up to approximately 15 trillion yen annually. This background includes not only productivity losses due to absenteeism and decreased performance during work among the working-age population, but also the long-term effects of increased mortality risk due to sleep deprivation leading to a shrinking labor force, and sleep deprivation among children and young people hindering academic achievement and skill development, thereby lowering the quality of the future workforce. *1

Business Initiatives Centered on SleepTech

To address this societal issue, the Company primarily approaches it with services that combine sleep and wakefulness with technology. We aim to solve sleep problems with products developed by a team with a unique perspective and high expertise.
