TOKYO, June 4 (Reuters) - Japanese government bonds

(JGBs) fell on Thursday, sending yields higher across the curve,

as investors weighed firmer Bank of Japan rate-hike expectations

and global inflation concerns.

Here are a few details:

* The yield on the benchmark 10-year JGB

climbed 2.5 basis points (bps) to 2.665%. The two-year yield

, the one most sensitive to Bank of Japan policy

rates, gained 1.5 bps to 1.415%. Yields move inversely to bond

prices.

* BOJ Governor Kazuo Ueda said on Wednesday the central bank

must discuss the pros and cons of raising interest rates if

upside inflation risks outweigh downside risks to the economy.

His comments reinforced expectations that the BOJ will raise its

key rate from 0.75% to 1% at its June meeting.

* "The speech delivered yesterday by Bank of Japan Governor

Ueda contained many important hawkish messages," Ataru Okumura,

a senior rate strategist at SMBC Nikko Securities, said in a

note. "It is possible that he will raise interest rates at the

June meeting while emphasising more strongly than before the

BOJ's intention to continue raising rates beyond that point."

* Inflation concerns hung over global debt markets, with

U.S. Treasury yields climbing overnight amid renewed U.S.-Iran

hostilities that pushed oil prices higher and revived inflation

concerns.

* "Negative factors surrounding ultra-long-term bonds, such

as inflation concerns and worries about fiscal expansion, have

not been resolved," Keisuke Tsuruta, a senior bond strategist at

Mitsubishi UFJ Morgan Stanley Securities, said in a note.

* The 20-year yield advanced 4 bps to 3.575%,

while the 30-year yield added 2.5 bps to 3.880%.

The yield on the 40-year JGB, Japan's longest

tenor, increased 0.5 bp to 3.755%.
