Main social security systems and expenditure can be divided into following categories.
The total social security benefits (note2) in 1994 were about ¥70 trillion, the equivalent of 16.3% of the national income. The pension benefits were the largest item and the medical service costs the second (See statistical data in Appendix). These two items of expenditures (benefits) in 1997 amount to more than 95% of the total social security benefits. The proportion of other expenditures, such as personal social services and family policy, are estimated to become higher in future
