Denka Clinic, a medical facility operated by the Kojunkai Medical Corporation in Kanna, Sodegaura City, Chiba Prefecture, began outpatient care in January 2026 as an internal medicine clinic. Serving as a primary care provider for the local community, they offer initial medical care for everyone from children to the elderly. The clinic takes time to listen to patients, provides thorough explanations, and delivers compassionate care. They perform same-day laser surgery for lower limb varicose veins (visible veins and lumps), with varicose vein consultations available by appointment. The clinic also has a system in place to refer patients to advanced medical facilities such as Kimitsu Central Hospital, Teikyo University Chiba Medical Center, Chiba University Hospital, and Sodegaura Satsukidai Hospital, depending on symptoms and patient preferences. To reduce waiting times and prevent infections, an online and automated telephone registration system is available, allowing same-day appointment booking. For patients with fever, regardless of whether they have COVID-19, the clinic separates waiting areas by using their own vehicles or designated waiting rooms, minimizing contact with regular patients. The clinic also accepts cashless payments and provides parking and barrier-free facilities.
