At the event, LEESOL will showcase its 'sleepisol+/blissol' sleep care devices featuring its proprietary 'CS-tACS' technology. The company will present the relationship between sleep and corporate health, the potential for using these devices as employee benefits, and case studies of research and implementation in South Korea.

Addressing Management Issues for Japanese Companies

In recent years, decreased productivity and mental health issues caused by sleep deprivation have become major global social issues. Japan, in particular, faces chronic sleep deprivation, with average sleep duration among the lowest in the OECD. Sleep problems are not merely personal issues but critical factors affecting labor productivity, corporate competitiveness, and overall societal vitality.

Consequently, employee health is increasingly recognized as a vital resource for sustainable corporate growth. More companies are strengthening initiatives for sleep improvement and stress care as part of health management and wellbeing strategies. Leading firms are treating sleep as a part of human resource strategy, actively implementing measures to support employee condition.

LEESOL has addressed sleep challenges through its 'sleepisol' series, utilizing its patented 'CS-tACS' (Cranial Stimulation-transcranial Alternating Current Stimulation) technology. In South Korea, the company has expanded its business through multiple generations of product improvements and clinical research, now achieving annual sales of approximately 1 billion JPY. It has been designated a 'Baby Unicorn' startup by the South Korean government for its high growth potential.

Leveraging this experience and knowledge, LEESOL is now launching full-scale operations in Japan, focusing on corporate health management and employee benefits. This exhibition marks the first step, where attendees can experience the 'sleepisol+' device, designed for improved sleep quality, concentration, relaxation, and stress management.
