In an effort to improve public awareness of sleep-related issues and address low consultation rates, the Japanese government is reforming its healthcare system by introducing clearly defined “sleep disorder” categories in medical departments, making it easier for patients to seek appropriate care.

TOKYO, JAPAN (MERXWIRE) – According to the Japanese Society of Sleep Research, only about 14% of individuals suffering from sleep disorders in Japan actually seek medical treatment. This suggests that many people continue to endure insomnia or poor sleep quality without professional help. One key reason is the lack of clarity in medical department classifications, leaving patients unsure of which specialty to consult.
To address this issue, the Japanese government has begun revising the healthcare system by explicitly incorporating the term “sleep disorder” into department names, such as “Sleep Disorder Internal Medicine” and “Sleep Disorder Psychiatry.” The move is expected to improve accessibility and reduce psychological barriers to seeking treatment.
Japan has long struggled with insufficient sleep. A study published in the international medical journal Sleep Medicine found that the average daily sleep duration in Japan is approximately 6 hours and 15 minutes, ranking the lowest among surveyed countries. Data from the Ministry of Health, Labour and Welfare also shows that around 30% of the population perceives themselves as sleep-deprived, highlighting the issue as a growing public health concern.
Experts note that sleep disorders not only affect daily life and work performance but may also increase the risk of chronic illnesses. However, symptoms are often overlooked or mistaken for temporary stress, leading to delays in treatment.
As reforms continue, the Japanese government hopes that clearer medical classifications and improved guidance will encourage more individuals to seek early treatment, ultimately enhancing the nation’s overall sleep health.
