Report on the results of the 2022 edition of Japan’s ‘Sleep Deviation®’ survey.
Sleep duration in Japan, the world’s shortest sleepers, increased by 21 minutes in 3 years. Sleep gadget usage rate is only 4.3%, but there is room for growth in the Japanese sleep tech market.
~Three years have passed since the establishment of Brain Sleep. Expanding business with improving sleep duration in Japan~

Brain Sleep, Inc. has conducted the Sleep Deviation® survey of 10,000 people in 47 prefectures across Japan for the years 2020, 2021, and 2022. The Sleep Deviation Score® is a method that comprehensively scores productivity, stress level, and risk of sleep apnea syndrome (SAS), in addition to items that directly determine sleep status, such as sleep habits and sleep debt.
We will use the results of this survey in the future to conduct various activities aimed at further improving sleep in Japan.
