TOKYO, Oct 21 (Reuters) - Japan's Nikkei share gauge

continued its record run on Tuesday, ahead of a parliamentary

vote expected to confirm fiscal dove Sanae Takaichi as the

nation's next prime minister.

The Nikkei 225 Index climbed 1% to 49,663.45 in

early trade, and is poised for a record close, if the current

momentum persists. The broader Topix gauge was up 0.6%.

The nation's stocks surged on Monday after Takaichi's ruling

Liberal Democratic Party secured a new coalition partner in the

Japan Innovation Party, known as Ishin, to firm up her support

in the Diet.

The Nikkei hit successive highs earlier this month on

expectations of further stimulus after Takaichi won a vote to

lead the LDP. But her assent to the prime minister's seat was

delayed after long-time political partner Komeito split from the

LDP's coalition.

A parliamentary vote to choose the premier is scheduled for

the afternoon. Market attention now turns to who may fill out

Takaichi's cabinet for signs of how the new government will

approach spending and debt management.

Takaichi has finalised a plan to appoint former regional

revitalisation minister, Satsuki Katayama, as finance minister,

broadcaster FNN reported on Tuesday.

Reaction in the Japanese government bond (JGB) market was

muted early on. The 10-year JGB yield fell 0.5

basis point (bp) to 1.66%, while the two-year yield

fell 1 bp to 0.935%.
