Yonezawa Eye Clinic, located in the heart of Yonezawa City in Yamagata Prefecture, is an ophthalmology clinic operated by the medical corporation Chikeikai. The clinic is notable for its active research activities by its physicians. In January 2026, a letter paper by Dr. Yu Kaneko was published in JAMA Ophthalmology, an internationally authoritative journal in the ophthalmology field, demonstrating the clinic's high academic standards. Regular examinations by specialists from Yamagata University are also conducted, and the clinic plays a role as a core ophthalmology clinic in the region. The clinic is open six days a week, with Tuesday afternoons used for surgery, ensuring a well-established system for both consultations and procedures. English language support is available, making it accessible for patients who are not Japanese speakers. The clinic accepts credit cards, debit cards, and electronic payments, and is equipped with parking and barrier-free facilities, making it convenient for patients visiting by car or with physical disabilities. The clinic is closed on Thursdays, Sundays, and holidays, so it is recommended to check the clinic schedule before visiting.
