Tokyo stocks edged lower in early trade, amid uncertainty over additional tariffs and after U.S. authorities told Nvidia semiconductors they would need export permits to China.

The Topix fell 0.1% to 2,512.02 as of 9:28 a.m. Tokyo time

The Nikkei fell 0.3% to 34,176.54

Advantest was the biggest contributor to the Topix decline, down 4.4%. Of the 1,689 stocks in the index, 986 rose and 598 fell, while 105 were unchanged. "The tighter restrictions on Nvidia products show that tensions between the U.S. and China are escalating, and it's hard to invest in technology stocks unless the overall picture of tariffs and semiconductor curbs is clear," said Ryuta Otsuka, a strategist at Toyo Securities Co.
