Hikari no Sato Clinic, located in Kai City, Yamanashi Prefecture, is an internal medicine clinic operated by Iroudoujin Kojikai Medical Corporation. The clinic is situated within the grounds of a comprehensive welfare facility run by Social Welfare Corporation Hikari no Sato, which was established in 1994 with approval from Yamanashi Prefecture. This integrated complex includes a special nursing home for the elderly, a geriatric health facility, care housing, and a day service center. As a core medical institution within this multi-facility complex, the clinic plays a vital role in supporting the daily health management of users, primarily elderly members of the local community. The corporation originated in elderly welfare and opened a child care facility in 2005, implementing Yamanashi Prefecture's first initiative where elderly residents and children interact while living on the same grounds. Based on this deep understanding and extensive experience in welfare, the clinic provides community-based medical care with inpatient facilities, going beyond simple outpatient services. The facility is barrier-free, creating an environment where patients with physical disabilities and elderly patients can receive care with peace of mind. Parking is also available, making the location accessible for those who find public transportation difficult. The clinic is closed on Sundays, public holidays, and during the year-end and New Year period, with services primarily offered on weekdays.
