TOKYO, Aug 8 (Reuters) - Japanese government bond (JGB) yields were mixed on Thursday, with a rise in their U.S. peers overnight creating upward pressure while better-than-expected demand at an auction for 30-year JGBs supported buying.

The market largely brushed off a summary of opinions from the Bank of Japan's July meeting released on Thursday, which showed that some policymakers called for further interest rate hikes.

BOJ Deputy Governor Shinichi Uchida on Wednesday played down the chance of a near-term rate hike, saying it will not raise rates when markets are unstable.

U.S. Treasury yields rose on Wednesday after the Treasury Department saw soft demand for 10-year notes and as companies rushed to sell debt as risk appetite improved.

Yields move inversely to bond prices, rising as bonds are sold.

JGB yields climbed across the curve during morning trade in response, but were mixed after solid sales were reported at an auction for 30-year JGBs. The corresponding yield reversed course to fall 7 basis points (bps) to 2.115% after earlier touching a one-month high of 2.24%.

The bid-to-cover ratio, a common measure of demand at auctions, improved to 3.47 from 2.97 in July.

The 10-year JGB yield fell 2 bps to 0.855%, down from a session high of 0.895%.

Benchmark 10-year JGB futures rose 0.16 yen to 145.12 yen.

Markets have been volatile this week on U.S. recession fears and the unwinding of investments funded by a cheap yen, as well as concerns about how fast the BOJ would tighten monetary policy.

"The market likely expects additional rate hikes have been pushed back" given BOJ Deputy Governor Uchida's remarks, said Makoto Suzuki, senior bond strategist at Okasan Securities.

On the other hand, uncertainty about the state of the U.S. economy and pace of rate cuts by the Fed may remain for now, he added.

The two-year JGB yield, which corresponds more closely with monetary policy expectations, inched up 2.5 bps to 0.29% but remained well off a more than 15-year peak of 0.465% touched on Aug. 1.

The five-year yield ticked up 0.5 bp to 0.415%.

The 20-year JGB yield slid 6 bps to 1.68%. (Reporting by Brigid Riley; Editing by Mrigank Dhaniwala)
