Kumagai Eye Clinic, located in Komagome, Toshima Ward, Tokyo, operates as a specialized ophthalmology clinic. Clinic hours are from 9:30 AM to 1:00 PM and 3:00 PM to 6:00 PM, with closures on Wednesdays, Sundays, and public holidays. For time-consuming examinations such as mydriasis testing, visual field testing, and eyeglass fitting, registration closes one hour earlier. The clinic does not provide care for patients who require new contact lens prescriptions or regular checkups every three months, and for new patients or those returning after a long absence, general examinations including visual acuity and intraocular pressure are conducted to determine treatment methods. The clinic also features English support and barrier-free accessibility.
