The Tokyo Stock Exchange opened lower on the first trading session of the month, with the benchmark Nikkei falling 0.44% to 63,014.43, a loss of 275 points.
The decline followed a correction in US stock markets, where selling concentrated on technology and semiconductor shares after Intel's plunge and doubts about the profitability of investments in artificial intelligence. Uncertainty over the US midterm elections also weighed on sentiment.
On the foreign exchange market, the yen strengthened against the dollar at 157.70 and traded at 176.10 against the euro.
