About Us

We have been serving patients with organ failure since 1971, especially those with renal failure, hepatic failure and Type I diabetes mellitus. We have pioneered many cutting-edge treatments and studies in Japan, including organ transplantations, immunosuppression therapies, hemodialysis, surgeries in organ failure patients and whole-body management.


Our institute has performed more than 4,500 renal transplantations to date as one of the nation’s largest renal transplantation programs. Our department performs about 100 renal transplantations every year. We also perform pancreas transplantation for type 1 diabetic patients, many of whom with simultaneous renal transplantation. Although we do not have a liver transplantation program at present, we also provide care for patients who have undergone liver transplantation.


As specialists in the field of renal failure, we make more than 500 arteriovenous fistulas and perform over 800 cases of percutaneous transluminal angioplasty every year. Peritoneal dialysis catheter placement is also available at our center, as another means of dialysis. Surgical treatment for secondary hyperparathyroidism, a complication of long-term renal failure, as well as surgical treatment for gastrointestinal diseases for patients with renal failure is also available.



Request An Appointment

When you visit our outpatient clinic, you will need a letter of referral from your primary health care provider on your first visit.

Please visit our appointment center on the basement floor of the outpatient ward, or call the appointment booking center at 03-3353-8138. We are closed on the third Saturday of each month, as well as Sundays and holidays.

You may visit without making an appointment, as long as you arrive at the outpatient ward before 11AM, however in this case you should be prepared for a long wait as patients with appointments will be seen first. Reception for outpatients begins at 7:30AM. In cases of after-hours emergency, you will go through the emergency room first. Please call 03-3967-1181 before coming to the ER.



Renal Transplant Program

Renal transplantation is a treatment for renal failure. You may receive a kidney from either a deceased donor or a live donor. If you have a family member willing to donate a kidney, please come to the hospital with your prospective donor. They will need to be either a) within the sixth degree of consanguinity, or b) within the third degree of affinity. You will need a letter of referral from your primary health care provider on your first visit.

You can also opt to be added to the national transplant waiting list to receive a kidney from a deceased donor. To register in the list, you will need to either a) be on regular hemodialysis treatment for renal failure, or b) have end-stage renal disease with an eGFR below 15mL/min.

Pancreas Transplant Program

If you have been diagnosed with type 1 diabetes and have severe episodes of dangerously low blood sugar levels despite good insulin control, you may be eligible for a pancreas transplant. A transplanted pancreas should start producing insulin, relieving many diabetes symptoms. 

Two types of pancreas transplant are currently offered in our program:

  1. Simultaneous pancreas-renal transplantation

           Patients with renal failure due to diabetic complications are given a kidney and a pancreas from the same donor.

  1. Pancreas after renal transplantation

           If you have already undergone renal transplantation, but need a pancreas transplantation to cure difficult-to-manage type 1 diabetes, you may be eligible for a pancreas after kidney transplant.

As both transplants are from deceased donors, you will first need to apply to the Japan Organ Transplant Network. To be registered in the pancreas transplant program, you will need to undergo various medical tests to determine whether you are qualified to be a pancreas transplant recipient. It would take more than a half year. If you decide to register with us, please bring a letter of referral from your primary health care provider for your first visit to our clinic.
