TOKYO, Feb 10 (Reuters) - Japan's Nikkei share average

declined in early trade on Monday as tariff risks and losses

across all three U.S. stock indexes last week dragged on

investor sentiment.

The Nikkei was down 0.3% at 38,684.12 as of 0005

GMT, while the broader Topix stumbled 0.2%.

Amid news that U.S. President Donald Trump will announce new

25% tariffs on all U.S. steel and aluminium imports on Monday,

Japanese steel makers fell around 1%.

Nippon Steel ( NISTF ) was down 2%.
