Japan FY 2018 draft budget to be record high for 6th straight year

Japanese government bond issuance is ... around 34 trillion yen

Swelling social security spending will likely reach around 33 trillion yen

So Japan's social security spending could be said to be funded by debt, rather than savings or even taxation.

Well, long may this last...

Government bond issuance is expected to decline from fiscal 2017 to around 34 trillion yen, reflecting increased tax revenue during fiscal 2018.

Hang on! I thought the increased tax revenue was to be used for free education and increased child and aged care. I don't recall anything about using the revenue to prop up the failed pension system or to increase the military budget.
