Nisshin Gastroenterology & Surgery, located in Sakae, Nisshin City, Aichi Prefecture, has specialized in gastroenterology since opening in 1999. The clinic treats gastrointestinal diseases of the esophagus, stomach, large intestine, liver, gallbladder, and pancreas, addressing symptoms including loss of appetite, nausea, heartburn, vomiting, and stomach pain. For diagnosis, the clinic utilizes electronic endoscopes with miniature cameras and ultra-thin gastroscopes as narrow as a pencil to diagnose gastritis, gastric ulcers, duodenal ulcers, and stomach cancer. The nasal insertion method reduces nausea while allowing conversation with the physician during examination, and H. pylori testing is available. Supporting this advanced diagnostic system is Director Dr. Masato Hayakawa, a certified physician of the Japan Gastroenterological Endoscopy Society and a board-certified surgeon of the Japan Surgical Society. The clinic prioritizes building trust with patients and their families, employing a health management system that supports family-wide care. The clinic clearly explains matters outside its specialty and refers patients to trusted hospitals and physicians. H. pylori rapid testing uses the urea breath test where urea is ingested and breath analyzed. Facilities include parking and barrier-free accessibility, with English language support available. Additionally, an online eligibility verification system has been introduced for verifying pharmaceutical information and specific health screening data.
