Kumai Clinic is located in a residential area of Kasugai City, Aichi Prefecture, approximately a 10-minute walk from Kachigawa Station. The clinic specializes in internal medicine and also offers gastroenterology, respiratory medicine, cardiology, pediatrics, and rehabilitation. Guided by the philosophy of "heart-to-heart medicine" and "community-rooted medicine" inherited from the previous generation, the clinic provides care for patients of all ages, from infants to the elderly. Consultations are available Monday, Tuesday, Wednesday, and Friday mornings and afternoons, and Saturday mornings only. As the clinic does not operate on a fully reservation-based system, it is well-suited for handling sudden illness with flexibility. One of the clinic's distinguishing features is its home medical care service for patients who have difficulty visiting in person. Visiting medical care, rehabilitation, and nutritional guidance are provided 365 days a year, 24 hours a day, offering comprehensive support for home-based recuperation using examination and treatment equipment comparable to in-clinic care. The clinic also operates an adjacent sick-child daycare room called "Kumachan Byoji Hoiku-shitsu," which accepts children recovering from illness when parents are unable to take time off work. Beyond treatment, the clinic is committed to health maintenance through nutritional consultations, guidance, and regularly held nutrition classes. English-language support is available, and the facility offers both parking and barrier-free access.
