TOKYO, Aug 22 (Reuters) - Japanese government bond (JGB)

yields edged up on Thursday, with moves subdued as market

participants awaited remarks from the heads of both the Bank of

Japan and the Federal Reserve on Friday.

Mid- and long-term yields rose as investors continued to

adjust positions amid easing fears of a U.S. recession.

But the moves were cautious ahead of BOJ Governor Kazuo

Ueda's appearance before Japan's parliament on Friday, where he

will discuss the bank's decision last month to raise interest

rates.

The benchmark 10-year JGB yield was up just

0.5 basis point (bp) at 0.87% as of 0415 GMT, while 10-year JGB

futures fell 0.14 yen to 144.84 yen.

Markets will be watching to see whether Governor Ueda

changes his hawkish stance given the recent market turmoil, said

Yurie Suzuki, a market analyst at Mizuho Securities.

"There's a strong sense of uncertainty around that... It's

difficult to make a move under these circumstances."

The BOJ's hawkish turn is seen as a contributing factor in

the biggest single-day rout in Japanese equities since the 1987

Black Monday crash.

Suzuki said some market participants are again considering

the possibility of another rate hike in Japan within the year

after the BOJ released research papers this week that supported

the argument that broadening inflationary pressures warrant

raising rates steadily.

Fed Chair Jerome Powell will speak on Friday at the Jackson

Hole Economic Symposium, with the markets expecting the Fed to

begin cutting rates in September. Global investors will be

listening for hints on the size of the rate cut and the policy

outlook.

Elsewhere on the curve, the two-year JGB yield

rose 1.5 bps to 0.36%, and the five-year yield

ticked up 1 bp to 0.485%.

The 20-year JGB yield and the 30-year JGB

yield were both flat at 1.7% and 2.08%,

respectively.
