TOKYO, Feb 17 (Reuters) - Japanese government bond (JGB) yields fell to multi-week lows on Tuesday in holiday-thinned trading, tracking sharp declines in U.S. Treasury yields last week.

The benchmark ?10-year JGB yield fell 8.5 basis points (bps) to ?2.125%, its lowest since January 9. The 20-year JGB yield slid 11 bps to 2.970%, the lowest ?since the end of December.

Japan will likely see annual bond issuance

surge ?28%

three years from now on rising debt-financing costs, Reuters reported, ?casting doubt on ?premier Sanae Takaichi's argument that the country can deliver tax cuts without boosting debt.

"The news would have ?prompted investors to sell bonds and push ?the yields higher, but that was offset by the sharp declines in the U.S. Treasury yields," said Katsutoshi Inadome, a senior ?strategist at Sumitomo Mitsui Trust Asset ?Management.

Bond ?yields move inversely to prices.

The U.S. two-year bond yield fell to its lowest in four months last Friday, as cooler-than-expected inflation data for January ?underpinned hopes for rate cuts by the Federal Reserve.

U.S. markets ?were shut on Monday for Presidents' Day holiday.

Holidays in Asia have curbed trading volumes, leading JGB yields to fall more sharply on Tuesday and negatively affecting the outcome of a five-year JGB auction, said Tomoaki Shishido, a senior rates ?strategist ?at Nomura Securities.

The markets in mainland China, Hong Kong, ?Singapore, Taiwan, and South Korea were closed on Tuesday for Lunar New Year holidays.

The ?5-year JGB yield fell 2.5 bps to 1.645% before the auction at 0130 GMT and extended the decline after the outcome was announced, last down 5.5 bps to 1.615%, its lowest since January 15.

With forward one-year overnight index swaps (OIS) two years ahead hovering between 1.7% and 1.75%, and the BOJ having raised its policy rate to ?1%, the five-year bond yield will trade around the 1.7% level going forward, said Yuki Kimura, bond strategist at Okasan Securities

The 30-year yield slipped 9 bps ?to 3.39%, its lowest since the ?end of December.
