At lunch, local time, the Japanese Nikkei 225 had fallen by more than 1.5 percent.
The decline comes in connection with new export figures for July, which show a decline of 2.6 percent on an annual basis.
Exports, which have been affected by the US trade tariffs, were, according to CNBC, worse than analysts' expectations.
It is also rough in South Korea, where Kospi is falling by 1.8 percent.
The stock exchanges in China are also seeing declines. Shenzhen and Shanghai are falling by 0.7 and 0.1 percent, respectively. The Hong Kong-based Hang Seng is at the same time at minus 0.4 percent.
Several major tech stocks fell in the US on Tuesday evening. Fellow companies in Asia are now following suit. Among other things, the Japanese tech conglomerate Softbank is falling sharply, and was at lunchtime down by 7.3 percent. The company is, among other things, the majority owner of the semiconductor company Arm.
