TOKYO, May 21 (Reuters) - Japan's Nikkei share average
surrendered early gains to end lower on Tuesday, as investors
slowed activity ahead of U.S. chipmaker Nvidia's earnings
report.

level for the first time in a month.
The broader Topix .TOPX fell 0.3% to 2,759.72.
"The Nikkei's momentum didn't last as investors refrained
from active buying before Nvidia's NVDA.O earnings on
Wednesday," said Shigetoshi Kamada, general manager at the
research department at Tachibana Securities.
Air-conditioner maker Daikin Industries 6367.T fell 4.68%

surging 13.79% after the company said on Monday its group net
profit is forecast to rise 65% and that it would buy back up to
8.2% of its shares.
Peer Tokio Marine Holdings 8766.T rose 2.34% after
announcing it would sell down cross-share holdings to zero by

The insurance sector .IINSU.T rose 2.29% to become the
best performer among the Tokyo Stock Exchange's (TSE) 33
industry sub-indexes.
Sompo Holdings 8630.T fell 6% as the insurer flagged a 45%
decline in its annual net profit.
KFC Holdings 9873.T rose to a daily limit high of 6,400
yen, after being untraded with a glut of buy orders, as the
operator of Kentucky Fried Chicken outlets said U.S. buyout fund
Carlyle Group CG.O offered to buy shares of the company at
6,500 yen per stock.
Of more than 1,600 stocks trading on the TSE's prime
