The Uwajima City National Health Insurance Kashima Clinic is an internal medicine clinic located on Toshima, a remote island in Uwajima City, Ehime Prefecture. Operating under the national health insurance system, it serves the medical needs of local residents. Toshima is an island in the Uwa Sea, and this clinic plays a vital role in providing medical access to island inhabitants. Consultations are available only during morning hours, from 9:15 a.m. to noon, with limited clinic days centered on Mondays, Wednesdays, and Fridays. Despite these constraints, the clinic fulfills its role as a primary care provider in this geographically isolated setting. English is listed as a supported language, allowing the clinic to accommodate patients who require communication in languages other than Japanese. Given the island's remote location, it is important to confirm clinic days and operating hours in advance before visiting. As a publicly funded medical institution rooted in the local community, this clinic serves as a cornerstone of healthcare on Toshima.
