TOKYO, Dec 6 (Reuters) - Japan's 10-year government bond yields fell on Monday, tracking a tumble in U.S. 10-year Treasury yields as uncertainty over the Omicron coronavirus variant dampened risk sentiment.
The 10-year JGB yield fell one basis point to 0.040%.
The benchmark U.S. 10-year Treasury yield fell to its lowest level since Sept. 23 at 1.335% on Friday, underpinned by demand for safe-haven debt, and were last at 1.38% on Monday.
With the absence of market-moving indicators on Monday, the 10-year bond yields moved along with the U.S. bonds in Asian trading, a market participant said.
The 20-year JGBs were not traded and their yield remained at 0.450%, while the 30-year JGB yield fell 0.5 basis point to 0.660%.
The 40-year JGB yield was flat at 0.705% after the bonds were not traded.
The two-year JGBs were not traded and the yield was unchanged at minus 0.120%.
The five-year yield fell 0.5 basis point to minus 0.105%.
Benchmark 10-year JGB futures rose 0.09 point to 152.2, with a trading volume of 12,475 lots. (Reporting by Tokyo markets team; Editing by Devika Syamnath)
