Saiwai Clinic, located in Gakuen Nishimachi, Kodaira City, Tokyo, is a medical practice offering comprehensive care centered on internal medicine along with dermatology and psychosomatic medicine. Situated about a 6-7 minute walk from either Hitotsugashi Gakuen Station or Ome Kaido Station on the Seibu Tamako Line, right in front of the Kodaira City Central Library, the clinic is easily accessible for local patients. Director Dr. Nobuyuki Sagehashi graduated from the Gunma University School of Medicine and spent the 1990s through the 2000s engaged in medical activities across multiple conflict zones and disaster areas, including a war-wounded surgical hospital in Afghanistan, refugee healthcare in Burundi, Africa, and medical reconstruction projects in the former Yugoslavia's Kosovo. He opened the clinic in 2013. The psychosomatic medicine department addresses physical and mental conditions stemming from work- or school-related stress. Dr. Sagehashi holds memberships in the Japanese Society of Plastic and Reconstructive Surgery, the Japan Diabetes Society, the Japanese Dementia Society, and the Japanese Society of Psychosomatic Medicine, and is active in both research and clinical practice, with published academic papers and books. The clinic is open on Wednesdays, Thursdays, Saturdays, and Sundays, and is closed on Mondays, Tuesdays, Fridays, and national holidays. The clinic does not accept workers' compensation insurance or treat children aged 10 and under, so patients should confirm these details before visiting.
