The Activator Method is the world’s most popular instrument adjusting technique, gentle, low-force approach to chiropractic care. This technique has been used safely on patients of all ages since 1967. It is highly effective for spinal, extremity, and muscular conditions.    It follows a certain protocol in balancing the body through proper identification of leg length inequalities.

Related symptoms such as joints and muscles such as back pain, stiff shoulders, Low back pain, neck pain, knee joint pain, shoulder joint pain, headache, numbness of limbs, sports problems, traffic accidents etc mainly use Activator Methods

1. Have them pose to check for spinal imbalances.
2. If there is an imbalance, a neurological erred signal is transmitted from the brain to the spinal cord, and the balance of muscles is disturbed and the leg length becomes uneven.
3.  When the activator is adjusted in dysfunctional area, the nervous system is activated and adjusted to normal function.

Work on Brain and Nervous System
It is the work of the brain and nervous system that keeps the body healthy.
People with good nerve flow can move freely and have no pain.
If the nervous system flows poorly, you can not move freely and suffer from pain.
Some people may wonder, "Can you fix my problem with this instrument ?” But we work directly on the "neural flow" that is one of the causes of pain so your problem will improve soon.
In addition, the flow of nerves is activated, and the healing power of the body itself is enhanced. As well as abnormalities in the skeleton and muscles, internal organs and dysfunction of the autonomic nervous system can be well balanced, and health can be derived.
Therefore, even if there is no pain, in particular, there are many patients who regularly visit our clinic for maintenance purpose and keep their health to keep their entire body in good condition.

A treatment that rewrites the false memory that the brain learned unconsciously into a healthy memory
"Therapies that focus on mind-body correlations and bioenergy blocks (EBs) and adjust for false memory with their associated learning memory patterns"

In PCRT, we regard the living body as an energy body, and we believe that the trouble that occurs in the living body is related to the bioenergy block where the living energy flowing through the living body stagnates.
In order to normalize the "work" of the living body, we adjust the bioenergy such as the nerve energy and the energy of "Qi".
In PCRT, it is considered that the causes of symptoms and diseases are caused not by a single cause but by various relationships, and the various relationships related to the cause are clarified and adjusted.
3.False Memory
In PCRT, various chronic symptoms are considered to be caused by memory of malfunction, and it is defined as “false memory" and adjusted to promote healthy brain plasticity.

Depending on the person, the symptoms may vary, but when we see the patient's pain and problems improved and their pleasing appearance, We are also happy.
Please do not hesitate to consult if you have any questions or problems. We will be happy to help you. Thank you in advance.


The first visit patients will have 45 minutes including explanations, examinations, treatments, hot packs etc. after filling out the questionnaire. From the second time onwards, it is less than 25 minutes by examinations, treatment (10 minutes), hot pack.
The treatment time for symptoms related to mental health is about twice as long as usual (25 minutes) and within 40 minutes in total including examinations and hot packs.
Junior high school students and below have no hot packs, so they will finish earlier.

A wide range of age groups, from infants to the elderly, mainly patients with musculoskeletal symptoms such as back pain, stiff shoulders, joint pain, sports disorders etc., but with allergic symptoms and mental problems Many patients are also coming to visit by word of mouth.

The number of treatments before improvement can be expected to be a certain level of healing process if trauma, but especially for chronic conditions, it varies depending on the type and degree of symptoms, duration of symptoms, and the cause of each. It is difficult to simply determine the number of treatments according to symptoms or illness. Some patients improve with one treatment, while others require more than 20 treatments. The degree of improvement of symptoms depends on the degree of symptoms, mainly the depth and complexity of the cause.


Especially in the case of chronic symptoms of unknown cause, it is thought to be the result of programming "habit", that is, the neural circuit of the brain,
which causes the symptoms without knowing. In that case, it is necessary to make the body remember from the unhealthy "habit" causing the conventional symptoms to the healthy "habit". In order to do so, it is necessary to receive repeated treatment as in the practice. By receiving repeated treatment, you will learn and memorize the habit of healing your body gradually, and the symptoms will be improved.

In chiropractic and manipulative treatment, it is accepted that cracking the joint is as a treatment purpose, but this hospital does not crack the joint. The idea of ​​"cracking the joints and correcting the displacement of the joints" seems to be a general idea, but there are many misconceptions in that idea.
The joint sound of "crack" tends to seem as if it adjusted the gap of the joint.
However, it does not mean that the joint displacement has been corrected only by the so-called "cavitation" (cavitation) that the pressure of the synovial fluid filling the joint cavity changes and the air bubbles repel causing a so-called "cavitation".
It is more important to normalize the function of the nerve than to "correct the position of the joints".
In our clinic, by adjusting the nerve transmission, that is, the nerve energy and the bioenergy, the treatment is performed for the purpose of normalizing the function of the muscle and settling the position of the joint in a place where it should be settled and improve the symptoms.

Basically, no painful treatment is given. Even if pain is caused only by the examination to check the movement of the normal joints, the examination and treatment are performed so as not to cause pain as much as possible.
Because the treatment table is electrically operated, even when it is difficult to lie on a treatment table (treatment bed) or it is difficult to turn over, you can lie down from the standing position without having to move the body.
We take care so that we can receive treatment easily without pain as much as possible. Please feel free to contact us if you have any concerns.

Treatment is available from 0-year-old children. For children between the ages of 0 and 3 years old, it is recommended that mothers also receive treatment.
the examination of the child up to about 3 years old performs a proxy examination through the mother's body. the treatment of the child of the child will be carried smoothly if the balance of the mother's mind and body is prepared in advance.
In addition, especially children from 0 to 3 years of age have a close relationship with their mother's mind. There is a small amount of influence of mother's subconscious mind on her children. In that case, the physical condition of the child will be improved by adjusting the physical condition of the mother.

Depending on the type of insurance, it may apply, but basically you will need to pay for treatment with cash. If you wish to make the necessary documents for insurance company, a fee of 5,000 yen with tax are required.

There is basically no need to change clothes, but it is helpful if you can come to the treatment with easy-to-wear clothes so it will be easier to test. We also have a clothes changing corner and lockers, so please bring exercise clothes, etc. Furthermore, please put your belongings, valuables and accessories in the lockers and receive treatment.

In our hospital, many mothers with children come to our clinic. Please be assured that we are also support your children.
During the mother's surgery, the staff will handle the children. For children with infants who are difficult to leave mothers, we are working to ensure that the children feel safe as much as possible.

As there is no parking lot in our hospital, if you come by car, please use the nearby coin park.

There are occasional holidays, so please make a reservation by phone or email. If you speak English only please call Dr. Yasui.
