TOKYO, Dec 19 (Reuters) - Japan's Nikkei share average

narrowed losses on Thursday as the yen weakened following the

Bank of Japan's (BOJ) decision to not hike interest rates.

The yen fell despite widely-held market expectations that

Japan's central bank would push policy tightening to January or

March, and was down about 0.14% at 155.035 per U.S. dollar by

0634 GMT.

The Nikkei ended the day 0.69% lower at 38,813.58

after finishing the morning session down 0.96%. The BOJ's

announcement came during the trading recess.

The broader Topix ended the day down 0.22% after

being 0.49% lower at the lunch break.

Japanese government bond yields came off early highs, with

benchmark 10-year note yields last at 1.08%, 2

basis points higher than Wednesday's close, after opening the

day at 1.095%.

"The BOJ likely decided to give it a miss, judging that it

would be fine to wait and confirm the trends for another month,"

said Takumi Tsunoda, senior economist at Shinkin Central Bank

Research Institute.

"But in any case, the conditions for another hike are being

met: Japan's inflation is on a slight upward trend and import

prices are again beginning to rise a bit due to the weak yen.

The BOJ should be able to raise rates easily at the January

meeting."

Japanese yields tracked a sharp rise in U.S. peers on

Wednesday, when the U.S. Federal Reserve cut interest rates by a

quarter point, as expected, but signalled a slower pace of

easing next year.

The Fed's hawkish stance sent U.S. stocks sliding, which

weighed on Japanese equities at the open.

Japan's rate-sensitive real estate sector was the worst

performer on the Nikkei, while financials was the only sector to

rise.

Among individual stocks, AI-focused startup investor

SoftBank Group stood out, tumbling 4.3%.

Nissan Motor ( NSANF ) ended a volatile session with a 6.5%

gain, the most among Nikkei constituents, after a local media

report said merger talks with Honda ( HMC ) could begin on

Monday. Honda ( HMC ) fell 2%.
