Your father, who is staying in Japan as a temporary visitor, is not eligible to join National Health Insurance because foreign nationals qualified for National Health Insurance are those who have completed Resident Registration and are expected to reside in Japan for three months or longer. However, if you are a member of Employee Health Insurance, and your father is recognized as your dependent, you may well ask your employer whether your Health Insurance can cover your father’s medical expense.
Ang tatay mo na isang pangsamantalang bisita sa Japan ay hindi maaaring maging miyembro ng National Health Insurance dahil ang mga kwalipikado lamang ay iyong nakapagparehistro at titira dito sa Japan ng isang taon o higit pa dito.
