TOKYO, Dec 24 (Reuters) - Japanese government bond yields rose slightly on Thursday, tracking firmer U.S. Treasury yields as Britain appeared to be close to a deal to leave the European Union, while hopes of a sustained global economic recovery also lent support. The 10-year JGB yield rose 0.5 basis point to 0.010%, while the 20-year JGB yield rose 1 basis point to 0.385%. The 30-year JGB yield rose 1 basis point to 0.620%. At the shorter end, the five-year yield ticked up 1 basis point to minus 0.120%. But the two-year JGB yield was flat at minus 0.140% after an auction of 3.0 trillion yen ($28.97 billion) two-year JGBs attracted solid bids. Benchmark 10-year JGB futures snapped their four-day winning streak to fall 0.16 point, their biggest decline in a month and a half, to 151.98.
