Critical Care and Emergency Medical Center/ER

In order to respond to the emergency medical care needs in Tokyo, the Critical Care and Emergency Medical Center/ER provides a wide range of critical and emergency medical care.

Medical services

Initial care is provided for acute illness, injury, burns, poisoning, and so on. The Critical Care and Emergency Medical Center/ER is equipped with emergency imaging examinations (CT, XR), and there are 8 beds of emergency ICU (EICU), 2 resuscitation rooms and examination rooms devoted to internal medicine, surgery, pediatrics, obstetrics and gynecology, ophthalmology, otorhinolaryngology, and dentistry. The emergency ward is equipped with 12 beds for immediate hospitalization and observation.

Treatment Policy

We aim to provide advanced medical care according to the disease condition to all patients who need urgent diagnostic treatment.


Because at least one doctor from each department is regularly stationed in the hospital, Emergency Services covers all areas of emergency care. In addition, through cooperation with the other departments, emergency imaging, specimen tests, and surgeries can be conducted 24 hours a day.

The establishment of comprehensive medical care systems in 2010 has enabled us to provide all patients requiring primary to tertiary care with emergency physicians' treatment, as necessary. In addition, construction work to install 6 ICU beds to be exclusively used for critical care and an emergency ward consisting of 14 beds took place from May to July, 2010, in order to establish a system to provide patients in a serious condition with emergency care on a 24-hour basis. Although the number of emergency patients temporarily decreased due to construction work, the number of those requiring tertiary emergency care has been particularly and rapidly increased since then.
