TOKYO, Aug 27 (Reuters) - Yields on the longest-dated

Japanese government bonds fell on Tuesday following a

well-received sale of super-long debt by the finance ministry,

while short-term yields tracked their U.S. peers higher.

The 30-year JGB yield fell 3 basis points

(bps) to 2.040% by 0545 GMT, while the 40-year yield

sank 2.5 bps to 2.300%.

The 20-year JGB yield eased 0.5 bp to 1.685%,

while the 10-year yield was flat at 0.880%.

Japan's Ministry of Finance offered 400 billion yen ($2.76

billion) of super-long JGBs in a liquidity enhancing auction,

100 billion yen less than it offered at the previous sale.

"It's been pretty tight in terms of supply and demand" in

the super-long end, said Shoki Omori, chief Japan desk

strategist at Mizuho Securities.

Pension funds and other long-term investors are buying the

bonds to lengthen duration into month-end, he said.

In terms of the broader trend for JGB yields, "it's really

up to the U.S.," Omori added.

U.S. Treasury yields rose on Monday, making back some ground

after the steep decline on Friday, when Federal Reserve Chair

Jerome Powell sent a much more dovish signal than the market had

expected. Yields ticked up further in Asian time on Tuesday.

Bank of Japan Governor Kazuo Ueda's determination to

continue with rate hikes will also continue to lift short-dated

JGB yields, Omori said.

The two-year JGB yield rose 0.5 bp to 0.36%,

while the five-year yield rose 0.5 bp to 0.495%.

Benchmark 10-year JGB futures fell 0.07 yen to

144.74 yen.
