Consultation hours are from 8:30 AM to 12:00 PM and 4:00 PM to 6:00 PM, with the clinic closed on Saturdays, Sundays, and public holidays.

Cervical cancer vaccinations are also available, reflecting the clinic's emphasis on preventive medicine. The clinic has introduced online eligibility verification, enabling patient registration via My Number Card as part of its efforts to build an efficient medical system. It also participates in the selected medical service system for generic drugs, providing patients with thorough information regarding medication costs. The facility features a parking lot and is barrier-free, making it accessible for those arriving by car or individuals with physical disabilities. Additionally, multilingual support including English is available, and credit card and electronic payment options are accepted, ensuring a highly convenient experience for patients. As of March 2025, the organization has further contributed to regional healthcare by opening Yutaka Family Clinic in Otoyoshi-cho, Masuda City.
