Sudo Hospital, operated by the medical corporation Sukeikai, is located in Annaka City, Gunma Prefecture and provides internal medicine-centered care. On Wednesdays, specialized urology is available in the morning and otolaryngology in the afternoon, with same-day reservations available for both specialties. Orthopedic surgery switched to a reservation system in February 2025 to reduce congestion and waiting times; patients without appointments for non-urgent cases will be seen in surgery or internal medicine instead. A fever outpatient clinic is available with consultation hours from 10:00 AM to 11:30 AM and 3:30 PM to 5:00 PM, and until 4:00 PM on Saturdays. The clinic is closed on Sundays and holidays, as well as the first three days of January, August 15th, and the two days at the end of the year. The facility offers English support, accepts credit card and electronic payments, provides parking, and features barrier-free access. Continuous mask-wearing is required within the facility for infection prevention.
