Children living in Katsushika City from age 0 until the first March 31 after turning 18 can see a doctor without paying the out-of-pocket share of insured care at the counter. There is no income limit, and inpatient, outpatient, and pharmacy costs are all covered. Just show the child medical certificate (Maru-Nyu, Maru-Ko, Maru-Sei) together with the health insurance card at the counter. The city takes part in Tokyo's program, so that Tokyo and Katsushika City together make out-of-pocket medical costs effectively zero until the end of the fiscal year in which the child turns 18.
