Koizumi Internal Medicine & Gastroenterology Clinic is located in Shohaku, Yawatahama City, Ehime Prefecture, and opened in September 2024 as a clinic specializing in internal medicine and gastroenterology. Director Yohei Koizumi, after years of service at Ehime University Hospital, has accumulated broad clinical experience as a gastroenterologist, treating conditions ranging from everyday ailments to serious diseases. The clinic was established on the site of Koizumi Obstetrics and Gynecology Clinic, which long served as a cornerstone of local healthcare in front of Yawatahama Station, carrying on that legacy of community medical contribution as the family doctor for the Hassai district. The clinic places great emphasis on clear explanations that minimize medical jargon and on providing consultations and treatment plans tailored to each individual patient. Office hours are from 9:00 to 12:30 in the morning and from 14:30 to 18:00 in the afternoon, with closures on the 2nd through 5th Sundays and public holidays. English-language consultations are available, and the clinic accepts credit cards and electronic payments. With parking facilities and barrier-free accessibility also in place, the environment is designed to be welcoming to a wide range of patients.
