Located in the heart of Chitose City, Hokkaido, the Chitose City Holiday and Night Emergency Medical Center (nicknamed "Sasaeru") is a primary emergency medical facility specializing in internal medicine, with extensive availability on weekday evenings, Saturday afternoons, and from 9 AM to the following morning on Sundays, holidays, and year-end/New Year periods. It is conveniently located approximately a 15-minute walk from JR Chitose Station and about a 10-minute drive from New Chitose Airport, with on-site parking available. The center features barrier-free design and offers multilingual support including English and Korean, creating an accessible environment for diverse patients. The primary focus of treatment is first aid, with prescriptions generally covering only the number of days until regular weekday medical services resume. After receiving care, patients are advised to follow up with their primary care physician or specialized medical facilities the following day or later, where continued treatment will be provided. The center treats relatively mild internal medicine conditions and does not perform surgical procedures, specialized examinations, or inpatient treatments. For emergencies such as sudden severe chest pain, calling 119 is essential. Payment is cash only, and patients must bring their health insurance card and medication notebook. As an emergency resource for sudden health changes during nights and holidays, it serves as an important facility supporting regional healthcare.
