Mitsui Clinic is an internal medicine clinic located in Honcho, Nirasaki City, Yamanashi Prefecture, providing medical services from 9 AM to 12 PM and from 3 PM to 6:30 PM. The clinic treats neurological conditions affecting the brain, spinal cord, peripheral nerves, and muscles through internal medicine approaches. Various symptoms are addressed, including limb weakness, numbness, difficulty speaking or swallowing, unsteadiness, gradual slowing of movements, hand tremors, headaches, and double vision. To precisely identify the location of neurological lesions, initial consultations typically require 30 minutes to one hour. Diagnostic services include peripheral nerve conduction studies and needle electromyography, with surface electromyography used to diagnose involuntary movements such as tremors. Abdominal ultrasound detects structural abnormalities within the abdominal cavity, while carotid artery and thyroid ultrasounds are also performed. Color doppler assesses blood flow direction and turbulent flow at stenotic sites, and pulse doppler measures blood flow velocity, aiding in the evaluation of arteriosclerotic conditions. Various X-ray examinations, electrocardiograms, and oxygen saturation tests are also provided. Patients are generally seen in order of arrival. Vaccinations are available upon request, and the facility offers parking and barrier-free access.
