Hirata Iin Rehabilitation Clinic, located in Minami-ga-oka, Onojo City, Fukuoka Prefecture, is a long-established medical facility that has supported community healthcare since its founding in 1979 (Showa 54). In 2019 (Reiwa 1), the clinic transitioned to a new structure as an internal medicine and rehabilitation clinic, pursuing improved quality of daily and social life for patients through a combined approach of general internal medicine and rehabilitation medicine. The clinic's distinguishing features include its ability to address a wide range of internal medicine conditions—including lifestyle-related diseases in both acute and chronic phases—while offering hydraulic equipment-based upper and lower limb muscle strengthening, joint range-of-motion improvement, and specialized physical therapy by licensed physical therapists, all within a single facility. Day care services are also available on the same floor, making the clinic suitable for those who wish to continue outpatient rehabilitation on an ongoing basis. Appointments are not required; patients are seen in order of arrival, and advance online check-in is also available. English-language support is provided, and the facility is equipped with a parking lot and barrier-free access, creating a welcoming environment for people from diverse backgrounds. Morning hours begin at 9:00 AM, and the clinic is closed on Sundays, public holidays, and year-end and New Year periods.
