Tsuru Clinic is an internal medicine specialty clinic privately established by Director Masaki Tsuru, located in Oki Town, Mizuma District, Fukuoka Prefecture. The clinic is rooted in the rural community of Oki Town, which extends to the southwest of central Fukuoka, serving as a familiar family doctor for local residents. The facility provides 10 free parking spaces, accommodating patients who travel by private vehicle given the limited public transportation access in the area. The clinic is barrier-free, ensuring that elderly patients and those with physical disabilities can visit with confidence. English language support is available, making the clinic accessible to those who require assistance in languages other than Japanese. Both new and returning patients are seen by appointment, helping to minimize waiting times. The clinic is closed on Sundays and public holidays, as well as during the year-end and New Year period (January 1–3) and the Obon period (August 14–15). As a community-based internal medicine clinic, it serves as a medical institution for everyday health management and the treatment of various internal medicine conditions.
