English National Health Insurance Japan: The 70% Reduction You Must Ask For
Japan cuts the flat part of your National Health Insurance bill by 70, 50 or 20 percent when household income was low. In Tokyo that is 65,200 yen a year down to 19,560, a gap of 45,640 yen. But it never arrives unless the city office knows your income, so zero income still has to be declared. Living alone, the 70 percent line is 1.08 million yen. Corrections stop after two years.
