TOKYO, Jan 28 (Reuters) - Japanese government bond

yields fell on Tuesday, tracking the declines in U.S. Treasury

yields overnight and as the Bank of Japan's (BOJ) bond-buying

operations saw a firm outcome for the bonds with super-long

yields.

The 10-year JGB yield fell 1.5 basis points

(bps) to 1.2%.

The two-year JGB yield fell 1 bp to 0.685% and

the five-year yield fell 1.5 bps to 0.87%.

U.S. Treasury yields tumbled to multi-week lows overnight as

investors sought the safety of government bonds amid a rout in

tech stocks on the emergence of a Chinese discount artificial

intelligence model.

"Demand for bonds with super-long maturities was supported

by a firm outcome of the BOJ's bond-buying operations," said

Miki Den, a senior Japan rate strategist at SMBC Nikko

Securities.

The BOJ, earlier in the day, offered to buy bonds with

maturities between one and 25 years in its regular bond-buying

operations.

The BOJ raised interest rates on Friday to 0.5%, the highest

since the 2008 global financial crisis, and revised up its

inflation forecasts.

SMBC Nikko's Den expects the BOJ to raise rates two more

times this year, in July and December, to 1%.

"The 10-year JGB yield may rise further beyond 1.2% if the

outcome of Japan's "shunto" spring wage talks is strong and

prices show faster growth," said Den.

The 20-year JGB yield fell as much as 1 bp to

1.89% and was last down 0.5 bps at 1.895%.

The 30-year JGB yield fell to as low as 2.25%

and was last down 0.5 bps at 2.255%.
