The Nikkei 225 index in Tokyo has risen by 1.1 percent. The broader Topix index is up 0.3 percent.
In Hong Kong, the Hang Seng index has instead fallen, down 0.3 percent.
The composite indexes in Shanghai and Shenzhen are showing increases of 0.2 and 0.5 percent, respectively.
The increase in Japan is driven, among other things, by tech companies such as Advantest, Softbank, and Tokyo Electron, writes CNBC.
This comes after the American semiconductor giant Nvidia's surge on Wall Street on Wednesday. The company is now valued at 3.77 trillion dollars, which means it is regaining its position as the world's highest-valued company ahead of Microsoft and Apple.
