Budget requests for social security for FY2027 (Reiwa 9) total JPY 39.7 trillion, against JPY 39.1 trillion for social security expenditure in the initial FY2026 budget. The material lists as issues for the FY2027 budget the triennial revision of long-term care and disability welfare fees and the revision of drug prices, the revision of public assistance standards, a review of the share of medical costs paid at the counter by people aged 70 and over and of the threshold for the 20 percent co-payment in long-term care insurance, and work on a target for the social security burden ratio.The taxes and insurance premiums the country collects pay for pensions, medical care, long-term care and child-rearing. All of that together is called social security. On November 4 a panel of experts at the Ministry of Finance discussed the money for social security, and the material from that meeting was published. The ministries asked for JPY 39.7 trillion for next year. The amount already set for this year is JPY 39.1 trillion, so the request is larger. Which parts will go up and which will be held down has not been decided yet.
