Nine Hours Collaborates with Chiba University Hospital for Sleep Data Research

Nine Hours and Chiba University Hospital Collaboration



On May 9, 2023, Nine Hours Co., Ltd., led by CEO Takahiro Matsui, officially entered into a memorandum of understanding (MOU) with Chiba University Hospital, under the supervision of Hospital Director Seiji Otori. This partnership aims to initiate research that utilizes sleep data collected from the guests at Nine Hours' future accommodation facilities opening in Chiba Prefecture.

Nine Hours is recognized for its unique capsule hotel experience. Currently, at select locations, the company offers sleep analysis services, where guest activities, snoring sounds, and facial images during sleep are monitored through built-in sensors in the capsule beds. This data is not only valuable for improving guest experiences but is envisioned to contribute to broader healthcare assessments.

The planned research will allow Nine Hours to gather and share these sleep data metrics, provided the guests consent for this usage. These metrics will then be analyzed by experts at Chiba University Hospital, with the objective of exploring methods of disease prevention and enhancing overall health.

Nine Hours aspires to create a new breed of accommodation service rooted in collaboration with medical institutions. By partnering with hospitals and research facilities, they want to engage in innovative developments centered around health and sleep quality. The MOU serves as a springboard towards establishing networks with other university hospitals and research organizations, as well as developing new healthcare services in conjunction with various corporations.

This approach indicates a pioneering model of collaboration between academia and industry, which aims to contribute to the advancement of preventive medicine and wellness.
