TOKYO, Feb 26 (Reuters) - Japan's Nikkei share average

touched a four-month low on Wednesday as worries about the

outlook of the U.S. economy and a stronger yen weighed on

investor sentiment.

The Nikkei fell 1.11% to 37,814.04 by the midday

break, after falling to as low as 37,742.76, its lowest level

since Oct. 25.

The broader Topix was down 1.06% to 2,695.74.

"Rising uncertainties hurt investor sentiment. The market

was concerned about the U.S. economy outlook, the impact of U.S.

tariff plans and the direction of the yen," said Shoichi

Arisawa, general manager of the investment research department

at IwaiCosmo Securities.

"The Nikkei had been underpinned by robust earnings of

domestic firms. But once the index fell below a psychological

barrier of the 38,000 level, investors were prompted to sell

more stocks."

The Nikkei fell below the 38,000 level for the first time

since Dec. 2.

The yen rose to its highest level since October as

data showed U.S. consumer confidence deteriorated at its

sharpest pace in 3-1/2 years in February.

In Japan, chip-making equipment maker Tokyo Electron ( TOELF )

slipped 5.95% to drag the Nikkei the most. Technology

investor SoftBank Group lost 3%.

Investors were cautious as they awaited Nvidia's ( NVDA )

quarterly earnings report later in the day, said Arisawa.

Mitsubishi Corp ( MSBHF ) lost 1.99% after surging 8.8% in

the previous session on the comments from billionaire investor

Warren Buffett about the ownership of Japanese trading firms by

his Berkshire Hathaway ( BRK/A ).

Mitsui & Co ( MITSF ) lost 2%.

The bank sector fell 2.06% as yields on Japanese

government bonds slipped.

Mitsubishi UFJ Financial Group ( MUFG ) and Sumitomo Mitsui

Financial Group ( SMFG ) fell 2.58% and 1.58%, respectively.

Beer maker Sapporo Holdings ( SOOBF ) rose 2.9% to become the

biggest percentage gainer on the Nikkei.
