Internal Medicine

Entrance to Consultation Rooms

Entrance to Consultation Rooms

When you have such subjective symptoms as stomachache, anorexia, or feelings of unwellness, or when you are unsure which section to visit, you will first see a physician at Internal Medicine.
At Internal Medicine we have a range of expert physicians for all areas including Cardiology, Gastroenterology, Neurology, Diabetes Mellitus/Thyroid Disease, Rheumatology, Hematology, Clinical Allergy/Asthma, and Nephrology. As we have many patients who along with other family members come to see our physicians regularly for several decades, we have the role of family physicians on our minds. Thus, we always try to provide wide-ranging medical care from the standpoint of general physicians.
  • Cardiology
    We mainly deal with cardiac diseases and blood pressure problems in this department. We provide medical care for cardiac diseases such as ischemic diseases (angina pectoris, cerebral infarction and aneurysm due to arterial sclerosis), cardiac failure, arrhythmia and cardiomyopathy and valvular disease, and hypertension and hypotension. Since patients with heart and blood pressure problems often have intercurrent diseases, we take care of them by paying attention to the whole body in collaboration with other departments.
  • Gastroenterology
    The department is responsible for the diagnosis and treatment of diseases related to digestive tracts such as the esophagus, stomach and bowel, as well as to digestive glands such as the liver, gall bladder, and pancreas. A variety of tests, including endoscopic tests of the upper and lower gastrointestinal tracts, abdominal ultrasonography, CT scanning and MRI, are carried out soon after the diagnosis thanks to our enhanced endoscopy and laboratory. We also proactively undertake sophisticated medical care for chronic hepatitis C patients, such as liver biopsy, and interferon therapy.
  • Neurology
    Just as there are "internal medicine" and "surgery" in medical care for circulatory organs and digestive organs, there are neurological internal medicine and neurosurgery in medical care for neurological diseases (the brain, spinal marrow, and peripheral nerves). Our Neurology specializes in clinical pathology from the perspective of internal medicine. It covers a wide range of areas, from acute conditions such as stroke and cerebral vascular disturbance, to chronic conditions such as neurological incurable diseases exemplified by Parkinson's disease.
  • Diabetes Mellitus/Thyroid Disease
    We specialize in conditions such as diabetes, hyperlipemia, pituitary disease (such as growth hormone and prolactin), thyroid disease, and adrenal diseases. Adult lifestyle-related diseases may often progress without patients recognizing any subjective symptoms. If any abnormality was detected in regular health checkups, earlier consultations at the hospital are recommended. We also provide medical care for Hashimoto's thyroiditis and Graves' disease.
  • Rheumatology
    We provide medical care for such diseases as rheumatism, collagen disease, and gout. Rheumatism is primarily a condition that fundamentally affects bones and joints, but when rheumatism progresses, it often affects other organs such as the lung and kidneys. It is generally believed to be an intractable disease. Thanks to the advance in treatment in recent years, however, we can now aim for the recovery of the nearnormal joint function. An early diagnosis allows it to positively treat collagen diseases such as systemic lupus erythematosus and scleroderma.
  • Hematology
    We diagnose and treat blood diseases. We also accept a wide range of consultations for anemia and other ordinary diseases.
  • Clinical Allergy/Asthma
    We diagnose and treat allergic conditions, mainly bronchial asthma, hay fever and prolonged cough. For bronchial asthma, please feel free to visit us if you cannot fully control symptoms at present.
  • Nephrology
    We diagnose and treat kidney diseases and hypertension. Kidney diseases are closely linked with metabolic syndrome and require wide-ranging and long-term treatment including diabetes and obesity. When dialysis treatment is required, we take time to explain it to patients, so that they can accept the treatment with informed consent.


For general and digestive surgery and breast surgery, we have doctors with proven track records of a large number of operations in their fields of specialty. In addition, we have expanded the line of equipment for checks of the upper and lower digestive tracts. Even when diseases require surgery, if the symptoms are relatively mild, in principle we carry out operations using an endoscope. Recovery is earlier in such cases, and we strive to shorten the time spent in the hospital as much as possible.
  • General and Digestive Surgery
    At the department, we diagnose and treat diseases of digestive tracts as well as gallstones, gallbladder polyps, inflammatory bowel diseases, and inguinal hernias, etc. We carry out minimally invasive (with minimal burdens on the body) endoscopy and laparoscopy in an effort to shorten the time spent in the hospital as much as possible.
  • Colorectal Surgery
    We objectively diagnose the defecation function of patients with complaints of constipation and defecation disorders, and then carry out biofeedback treatment or operations.
  • Breast Surgery
    We look after breast diseases and breast cancer. Many cases of breast cancer are curable if detected and treated early. In this department, specialist doctors have detected a large number of cases of micro cancer below several millimeters, early-stage cancers, and non-invasive cancers with the simultaneous use of mammography and echography and the proactive utilization of mammotome. In surgery, we identify sentinel lymph nodes to use them to diagnose the lymph node metastasis, thereby striving to narrow the extent of resection of breasts and lymph nodes, and improve the quality of life (QOL) of patients.


We specialize in the diagnosis and treatment of spinal fluid circulation disorders, such as cerebrospinal fluid reducing symptom, and normal pressure hydrocephalus. Cerebrospinal fluid reducing symptom is the leakage of spinal fluids due to accidents and other reasons, and displays such symptoms as headache, neck pain, dizziness, and a sense of fatigue. Normal pressure hydrocephalus means the accumulation of spinal fluids, which can lead to dementia and difficulty in ambulation. We conduct blood patch therapy for cerebrospinal fluid reducing symptoms, and the spinal fluid shut procedure for normal pressure hydrocephalus.


We comprehensively deal with a wide range of diseases and injuries to the organs that affect the posture and movement of the limbs and body trunks (the spinal column, limbs, joints, ligaments, nerves, and blood vessels).
More specifically, we focus on conditions such as disc hernias of the cervical and lumbar vertebrate, internal derangement of the knee, tendovaginitis, bone fractures, sprain, ligament injuries, rheumatism, lumbago, and sports injuries. We are the department particularly strong in hand surgery.

Obstetrics & Gynecology

Entrance-Obstetrics & Gynecology

Entrance-Obstetrics & Gynecology

At Sanno Hospital, recognized as a respected maternity hospital, obstetrics and gynecology is the clinical department proud of its tradition and achievements in our long history. We handle as many as 800 births a year. We are convinced that you will surely find the diagnosis and treatment by our experienced obstetricians and gynecologists very satisfying.
The Obstetrics & Gynecology department has reliable risk management and detailed outpatient care systems in place from the weeks of pregnancy. Doctor in charge continue to look after the same patient, which allow you to approach the moment of giving birth with a sense of security.
We also have team medical care structure in place for emergency responses, with a backup system of night doctors and on-call doctors ensuring the safety of mothers and children for 24 hours a day throughout the year.
As it comes to the last month of pregnancy, specialist pediatricians provide advice on how to deal with newborn babies at our "mental outpatient care" team.
You give birth in a private room in accordance with a birth plan worked out in advance, along with a maternity nurse attending. In order to dispel a feeling of fear about the pain of delivery any woman may have, we are proactively introducing the delivery with lesser pain, using epidural anesthesia in a bid to ensure a memorable, pleasant childbirth. You also have an option to use an LDR (Labor/Delivery/Recovery) room, which combines the functions of labor, delivery, and recovery rooms into one. Also, a Caesarean section can be performed in a well-equipped operating room under the management of the Anesthesia Department.
After birth, mother and a newborn baby stay in the same room, where a maternity nurse provides guidance on breast-feeding and bathing. Mothers can choose either Japanese or Western food. We can also offer special menus such as a la carte dishes and a celebratory meal.
Since between the discharge from hospital and a one-month medical checkup is a particularly important period, we support healthy childrearing by offering outpatient care for breast-feeding by maternity nurses and for babies by pediatricians.
We can provide post-birth vaccination for mothers with no immunity to measles and rubella.
We also cover a whole range of gynecology. We assist in the lifelong health management of women, ranging from cancer and other screening examinations to consultations during the period of adolescence and menopausal disorders.


Children's Room at Level 1
(for children & breast feeding)

The Pediatrics department has broadly two roles. The first is the diagnosis and treatment of pediatric diseases in general and health management, including immunization. The second is the clinical examination of babies born at Sanno Hospital and childcare consultations, with pediatricians specializing in newborn babies supporting the health of babies from the moment they are born. We also provide special outpatient care for pediatric allergy, developmental disorder/neurology, and pediatric cardiology.


When you find something wrong with your ears, nose, or throat, please visit the Otorhinolaryngology doctors. We also diagnose and treat dizziness and facial palsy, and provide specific immunotherapy (hyposensitization therapy) for allergic rhinitis. You can have a one-day sinus endoscopic surgery. We also provide advice on the use of hearing aids. We diagnose and treat voice, speaking and swallowing problems in cooperation with the Tokyo Voice Center on the same floor.
We also have a partnership with the IUHW, Mita Hospital, Head and Neck Oncology Center for the treatment of blotches and swellings.


We provide diagnosis and treatment for a whole range of dermatological diseases, including atopic dermatitis, rashes, hives, acne, and warts. Apart from diagnosis and treatment, we provide advice on skincare for babies, pregnant women, and the elderly. We also offer piercing, patch tests, and chemical peeling.


We diagnose and treat urological diseases and male genital diseases. We cover such diseases and symptoms as kidney stones, ureteral stones, urinary hemorrhage, inflammation of the bladder, urinary disturbance, urinary incontinence, hyperactive bladder, prostatic enlargement, impotence (erectile dysfunction, ED), and venereal diseases. We also pursue the early detection and treatment of kidney, prostate, and bladder cancers. For dialysis treatment of renal failure, we work together with the Sanno Medical Center.


Our Ophthalmology specializes in surgeries on the front part of the eye, such as cataract operations and refractive procedures, in addition to general ophthalmic care.
A cataract operation is designed to surgically remove the content of an opacified lens and replace it with an artificial lens. Along with the operation can also correct shortsightedness, longsightedness, and astigmatism, or remedy presbyopia, depending on the choice of lens. It is important that patients themselves choose what sort of vision to be realized after operation, based on thoroughgoing explanations by vastly-experienced doctors.
For refractive procedure, we adopt phakic intraocular lens (ICL) operations and excimer laser operations (laser in situ keratomileusis, LASIK; photorefractive keratectomy, PRK) for a wide range of treatment, including severe shortsightedness, longsightedness, and astigmatism.


We undertake tests and diagnosis by drawing fully upon highly sophisticated medical equipment and technologies, such as 1.5 tesla MRI, 64ch multislice CT, scintillation cameras (cameras for radioisotope examinations), and angiographic equipment.
Examination results can be seen in consultation rooms so that they can be used for real-time diagnosis and treatment.


Full-time anesthesiologists experienced in the whole range of clinical work are also engaged in postoperative management of patients. The administration of our four modern operating rooms is carried out under the guidance of the Anesthesiologist, who is responsible for providing anesthesia while ensuring safety. At Sanno Hospital, we take the initiative in having the Anesthesia Department manage singleday surgical procedures to collect eggs for infertility treatment. We take pride in this painless, safe, and pleasant procedure.

Dental Treatment Room

Dental Treatment Room

The life of teeth differs among individuals, but the number of sound teeth is said to gradually decline after the age of 60. We have the lineup of specialist staff to provide dentistry medical care, centering on dental implant treatment.
In addition to the dentistry medical treatment we check brushing not to neglect secular changes in the oral cavity, as of utmost importance for the daily use of dental implant. For recent dental implant treatment, the importance of postoperative maintenance has become clearer. For better precaution, we are working hard for oral care together with patients by stepping up maintenance by hygienists.

Rehabilitation Center

The Rehabilitation Center works for the recovery from bone and joint diseases such as bone fracture, gonalgia, backache and rheumatism, central nervous system diseases such as cerebrovascular diseases (hemiplegia) and Parkinson's disease, and respiratory diseases including chronic obstructive pulmonary disease (COPD), bronchial asthma, and postoperative lung cancer.
