Tama Seiseki Gastroenterology and Endoscopy Clinic, located on the 2nd floor of The Square, just a 1-minute walk from Seiseki-Sakuragaoka Station, specializes in gastroenterology and endoscopic examinations. A key feature of the clinic is its high-quality examination system staffed by experienced endoscopy specialists. By using sedatives, the clinic offers endoscopic procedures with minimal discomfort, and supports same-day combined gastroscopy and colonoscopy as well as same-day polyp removal when colorectal polyps are found. The clinic has also introduced a state-of-the-art AI endoscopy system to enhance early lesion detection. Inside the facility, private and semi-private spaces are available for bowel preparation, ensuring a comfortable environment before the examination. The clinic is open every day including weekends and holidays, with endoscopic examinations available on all days, making it easily accessible for those who have difficulty scheduling on weekdays. Starting from April 2026, endoscopic examinations and consultations by a female physician are offered on an irregular basis, expanding options for patients who may feel hesitant about the procedure. In addition to endoscopy, the clinic also provides general internal medicine services for colds, sudden abdominal pain, and lifestyle-related diseases, serving as a community primary care provider. Credit cards and electronic payments are accepted, and parking is available on site.
