TOKYO, April 30 (Reuters) - Japanese government bond

yields dropped sharply on Tuesday, catching up with a slide in

U.S. Treasury yields as Japanese markets reopened following a

national holiday.

The 10-year JGB yield declined 5.5 basis

points (bps) to 0.865% as of 0453 GMT, on track for its steepest

one-day decline since Dec. 20.

On Friday, it had risen as high as 0.93% for the first time

since Nov. 2. The rise came a day after equivalent U.S. yields

climbed to 4.739%, also the highest since Nov. 2.

Since then, the benchmark Treasury yield has dropped as much

as 13.6 bps to 4.605% ahead of crucial market events this week,

with the Federal Reserve deciding policy on Wednesday and

monthly U.S. jobs data due on Friday.

Meanwhile, there is little impetus for JGB yields to rise

based on domestic factors, after Bank of Japan Governor Kazuo

Ueda signalled on Friday that monetary conditions would remain

easy for now, and there would be no imminent tapering of its

monthly bond purchases.

The BOJ will publish the May schedule for bond purchases -

known locally as rinban - at 0800 GMT, with no alterations

expected.

"Given Ueda's dovish comments on Friday, what would be the

rationale for changing rinban now?" said Shoki Omori, chief

Japan desk strategist at Mizuho Securities. "It would completely

contradict what he said."

Benchmark 10-year JGB futures rose 0.62 yen to

144.55, rebounding from a near six-month low of 143.73 reached

on Friday. When bond prices rise, yields fall.

The two-year yield slid 3 bps to 0.265%, and

the five-year yield fell 4 bps to 0.465%.

The 20-year yield sank 4.5 bps to 1.640%. The

30-year yield lost 3.5 bps to 1.925%.
