It’s been forty years since I became a psychiatrist. At the age of fourteen, I set my aim to be a doctor, and by the age of twenty, I had decided to be a psychiatrist. I started my career as an intern at Nagoya Ekisaikai Hospital, where I worked for a year before interning at Nagoya University Hospital.
Since finishing my internship, I worked as a doctor at Aichi Prefectural Shiroyama Hospital(now Aichi Psychiatric Centre), a psychiatric clinic, for around ten years. Then I spent some time at the Nagoya University Hospital psychiatric department and subsequently I was employed as a counsellor at the health care centre of the Nagoya Institute of Technology.
After having been a public employee for thirty-seven years I took office at a clinic, which I took over after two years.


The theme of human existence - from its origins to its destination, from its birth to its future - has always interested me.
From my academic work, I’m aware that we recognise ourselves and others not only by using the five senses, but also at the level of cells and the body’s immune system.
However, I’m especially intrigued by the human mind, because we are one of only a few creatures on earth who have clear self awareness.


In my role as a clinical doctor, I’ve been trying to find out an answer to the question,“ where am I in my brain?“ i.e.“ identity and brain science“. 
This mystery has already been studied and its resolution attempted by scientists and doctors in the past. Especially the achievement made by the French and American psychiatrists, Henri Piéron and Nathaniel Kleitman respectively, which were remarkable in history.
As these great persons, I also chose sleep psychiatry as my main lifetime’s work.
Although I may be able to contribute only a little to the field, my passion is to resolve its secret using my knowledge of human brain waves, the biology and pathology of sleep.



I learn so many things from patients at the clinic everyday.  In addition to patients suffering from insomnia, anxiety, anemia, dysphoria, hallucinations, delusion, and loss of memory, people suffering with rarer hypersonic disorders such as insufficient sleep syndrome, sleep apnea syndrome, restless legs syndrome, REM sleep behavior disorder, sleep disorders such as delayed sleep phase syndrome, unconscious seizures, and conversion disorders such as convulsions come to our clinic.
We conduct highly accurate electrophysiologic studies such as electroencephalographic examination and multiple sleep latency tests by well trained medical technologists.
Our clinic requires an appointment for first visits and each subsequent visit, but we are making an effort to make diagnosis examinations as fast as we can.
Many patients discontinue treatment due to compatibility problems between the patient and physician. However, the emphasis on personal compatibility is thought to do more harm than good in medical treatment.  I actually do have associates who may be unsociable, but are excellent in diagnosis and treatment.  Friendliness may even have the risk of supplementing insufficient medical skills.  Therefore even if you request a transfer to a different hospital, please note that depending the course of treatment we may not recommend it.



In addition, if a patient already has a medical record with another doctor, please be aware that we cannot accept any patient without a letter of introduction from the previous doctor in charge.




We also conduct second opinions for patients under treatment at a psychiatric or sleep department.
We have a national network based on The Japanese Society of Sleep Research, hospital and clinic cooperation for patients with both physical and psychiatric disorders, and hospital and clinic cooperation for psychiatric disorders which require high expertise.  Health of the body and mind are inextricably linked, so we are serving to acquaint the best physicians we know.
Please feel free to visit our clinic.
