TOKYO, Oct 27 (Reuters) - Japanese government bond prices slipped on Friday as the market took cues from an overnight retreat by U.S. Treasuries and stronger equities, although the Bank of Japan's regular debt-buying operation limited the losses.
The benchmark 10-year yield and the 20-year yield rose 0.5 basis point each to 0.070 percent and 0.600 percent, respectively.
December 10-year JGB futures were down 0.02 point at 150.36, confined to a narrow 150.35-150.41 range.
The BOJ on Friday bought 710 billion yen ($6.22 billion) of five- to 40-year JGBs as part of its regular debt-purchasing scheme.
Treasury yields inched higher on Thursday, undermined by a soft auction of U.S. 7-year notes which saw demand at its weakest since August last year.
Japan's Nikkei stock average continued to ride a wave of global equity strength and rose to a fresh 21-year high, led by banking and tech shares.
