TOKYO, June 11 (Reuters) - Japanese government bond (JGB)

yields edged lower on Thursday, reversing earlier gains, after

U.S. forces confirmed the completion of overnight strikes on

multiple targets in Iran, easing some market concerns.

Here are a few details:

* The benchmark 10-year JGB yield fell 0.5

basis points (bps) to 2.675%, after briefly rising 1 bp earlier

to 2.690% earlier in the session.

* The five-year yield fell 0.5 bps to 1.93%,

reversing an earlier 0.5 bps rise to 1.940%. Yields move

inversely to bond prices.

* Market sentiment improved after the U.S. military's

Central Command announced that its strikes in Iran had

concluded.

* This development helped calm investor nerves, according to

Takahiro Otsuka, senior bond strategist at Mitsubishi UFJ Morgan

Stanley Securities.

* Meanwhile, the Bank of Japan said Governor Kazuo Ueda has

been hospitalised for medical treatment and will miss the June

15-16 policy meeting.

* While analysts expect a highly anticipated rate hike to

proceed as planned next week, Ueda's absence has raised concerns

on how the central bank will communicate its future policy

outlook.

* "There is some concern over what message the BOJ will send

at its June meeting without the governor, and the implications

this could have for its communication with markets," Keisuke

Tsuruta, a senior bond strategist at Mitsubishi UFJ Morgan

Stanley Securities, said in a note.

* Overnight, U.S. consumer inflation in May accelerated at

its fastest pace in three years, boosted by surging prices for

energy products amid the Middle East conflict, and giving more

ammunition for the U.S. Federal Reserve to keep interest rates

unchanged into 2027. U.S. Treasury yields also ended higher on

Wednesday on rising U.S.-Iran tensions.

* At the long end, Japan's 30-year yield rose

1 bp to 3.860%. The Ministry of Finance sold about 600 billion

yen ($3.74 billion) of 30-year JGBs on Wednesday. The auction's

bid-to-cover ratio, a measure of demand, declined to the lowest

in a year.

* The 20-year JGB yield climbed 1 bp to

3.565%.
