TOKYO, June 25 (Reuters) - Japanese government bond (JGB)

yields slipped on Thursday as oil prices fell close to levels

seen before the Iran conflict, easing inflation concerns.

Here are a few details:

* The benchmark 10-year JGB yield fell 4

basis points (bps) to 2.625%. Yields move inversely to bond

prices.

* Oil prices extended their decline on Thursday, edging

closer to pre-war levels as stranded tankers exited the Strait

of Hormuz following an initial accord to end the U.S.-Israeli

war with Iran, easing supply concerns.

* "The JGB yields reacted to the decline in oil prices, but

this could be a short-term move as there is still uncertainty

around the talks (to end the war)," said Naoya Hasegawa, chief

bond strategist at Okasan Securities.

* The market shrugged off comments from a hawkish Bank of

Japan board member Naoki Tamura, who said on Thursday the

central bank should raise interest rates once every few months

and stand ready to speed up the pace of hikes.

* "There was no surprise in his comments," said Hasegawa.

* The markets await outcome of an auction for the 20-year

bonds later in the day, which Hasegawa expects to be relatively

firm.

* The decline in yields in morning trade may have some

impact on the outcome, Hasegawa said.

* The 20-year JGB yield fell 2.5 bps to

3.540%. The 30-year yield was down 2.5 bps at

3.840%.
