TOKYO, Dec 20 (Reuters) - Japan's government will raise its long-term interest rate estimate, used to compile the state budget, to 1.9% for the next fiscal year from the current year's 1.1%, the Nikkei newspaper reported on Wednesday.

The higher estimate reflects rising Japanese government bond yields on expectations of a near-term exit from ultra-loose monetary policy, and pushes up the government's debt-financing cost, the paper said, without citing sources. (Reporting by Leika Kihara; Editing by Leslie Adler)
