TOKYO, Sept 14 (Reuters) - Japanese government bond prices retreated across the board on Friday as Tokyo stocks climbed to seven-month highs and reduced investor demand for safe-haven debt.
A regular debt-purchasing operation by the Bank of Japan, however, helped limit JGB losses.
The five-year JGB yield and the 10-year yield were both half a basis point higher at minus 0.070 percent and 0.110 percent, respectively.
The 30-year yield also rose half a basis point, to 0.840 percent.
The BOJ on Friday offered to buy 700 billion yen ($6.26 billion) of one- to five-year JGBs as part of its bond-buying scheme.
The Nikkei rose to its highest level since early February as risk appetite continued to improve on the back of an ebb in U.S.-China trade conflict concerns. ($1 = 111.8000 yen) (Reporting by the Tokyo markets team; Editing by Gopakumar Warrier)
