Located in Shimokoyama, Shimotsuke City, Tochigi Prefecture, Grimm Kodomo Clinic is an internal medicine clinic. As a children's and allergy specialist clinic, they provide specialized treatment for allergic diseases such as asthma, atopic dermatitis, food allergies, and allergic rhinitis. The director has personal experience with asthma and atopic dermatitis since childhood, and family members also have asthma, which influences their unique approach to patient care. For cedar pollen allergy treatment, they recommend early-stage therapy starting from late January to early February before symptoms appear. They also offer sublingual immunotherapy for cedar pollen allergy and house dust-induced allergic rhinitis, available for children aged 5 and above. The clinic places strong emphasis on infection prevention measures, including dedicated waiting rooms and examination rooms for patients with fever or suspected infections, alcohol-based sanitization, installation of multiple air purifiers and ozone generators, thorough ventilation, strict handwashing and hand sanitization, and mandatory mask-wearing by staff. English services are available, and the clinic is equipped with parking and barrier-free facilities.
