TOKYO—Japanese government bond yields rose on a firmer stock markets and as investors prepared for Tuesday's auction of 10-year debt.
The benchmark 10-year yield added 0.01 percentage point to 1.105%.
Some investors fear that the sale, totaling 2.2 trillion yen ($25.06 billion) could meet poor demand because the expected 1.1% coupon is too low to be attractive, analysts said.
If the auction result indeed turns out to be poor, yields will likely rise and prices, which move inversely to yields, are expected to decline.
