For years, the government has kept borrowing costs, as measured by assumed interest rates, low, effectively allowing the Bank of Japan (BOJ) to bankroll debt.
That is up from 25.25 trillion yen this year, the sources said, requesting anonymity as they were not authorised to speak publicly.
For the current fiscal year, the annual budget hit a record 114 trillion yen, boosted by steps to cope with COVID.
Social security accounts for nearly one-third of budget spending, making it the lion's share of the overall budget, followed by debt-servicing costs, which make up more than a fifth of the budget.
