A Comprehensive Medical System Supporting Mind and Sleep
At Kayukawa Clinic, our practice is grounded in board-certified psychiatric care, strengthened by specialized expertise in sleep medicine and extensive clinical experience in occupational health.
We look beyond presenting symptoms to conduct a comprehensive evaluation that includes prior treatment history, lifestyle background, work environment, and sleep patterns. Based on this thorough assessment, we develop individualized treatment plans grounded in medical evidence.
When advanced diagnostic testing or multidisciplinary care is deemed necessary, we collaborate closely with appropriate medical institutions to ensure that patients can continue their treatment with confidence and continuity of care.
Sleep Medicine Specialist (JSRS)
Our clinic has physicians with many years of experience in clinical psychiatry.
In addition, several doctors—including board-certified sleep medicine specialists from the Japanese Society of Sleep Research—work together to provide coordinated care.
Through our rotating schedule system, we are able to offer:
-
Prompt response to sudden changes in condition
-
Continuity and stability in ongoing treatment
-
Multidisciplinary perspectives through professional collaboration

Rather than relying solely on the judgment of a single physician, we share and review cases among our medical team when appropriate, ensuring careful and well-considered clinical decision-making.
Comprehensive Care for a Wide Range of Mental Health Conditions
Our clinic provides integrated care through close collaboration among a board-certified psychiatrist with expertise in occupational health and sleep medicine, addressing both mental health and sleep from a comprehensive perspective.
We treat a broad spectrum of psychiatric conditions, including depression, anxiety disorders, and adjustment disorders, as well as stress-related symptoms, chronic fatigue, and mood fluctuations. You are welcome to consult us even if you are unsure whether your symptoms meet a specific diagnosis.
We carefully consider the course of your symptoms, your personal and social background, and your work and home environment. Together, we develop a practical and sustainable treatment plan tailored to your individual needs.
Female Physician Available
A female physician is also on staff, and we can accommodate requests for a specific doctor whenever possible.
If you feel more comfortable speaking with a female physician, or find it difficult to discuss certain concerns with a male doctor, please let us know.
Sensitive issues—such as concerns related to adolescence or menopause—can be discussed in a supportive and respectful environment.
If you have a preference, please inform us at the time of booking your appointment.
