TOKYO, June 11 (Reuters) - Yields on 10-year Japanese government bonds fell for the second straight session on Friday, tracking declines in U.S. Treasuries yields, while some domestic investors who failed to buy U.S. debt shifted their money to JGBs, a market participant said.

The longer term bond yields also fell, with the 20-year JGB yield falling one basis point to 0.410% and the 30-year JGB yield sliding 0.5 basis point to 0.655%. The five-year yield fell 0.5 basis point to minus 0.120%. The two-year JGB yield was flat at minus 0.130%. The 40-year JGB yield was also unchanged at 0.705%.
