TOKYO, Jan 10 (Reuters) - Longer-dated Japanese government bond prices edged higher on Thursday, taking positive cues from a well-received 30-year debt auction.
The 30-year notes were sold at the lowest price of 99.60, higher than market expectations, and the auction drew bids of 4.03 times the amount offered.
The 30-year and the 40-year yields declined by one basis point each to 0.690 percent and 0.810 percent, respectively, while the 20-year yield dipped 1.5 basis point to 0.485 percent.
The benchmark 10-year yield traded flat at 0.025 percent, after hitting its lowest level in more than two years of minus 0.050 percent on Friday.
Ten-year JGB futures gained 0.11 point to 152.51, with a trading volume of 39,781 lots. (Reporting by Tokyo Markets Team; Editing by Sherry Jacob-Phillips)
