Why is the country doing it?
Japan has plans to build the fastest computer in the world to help create cutting-edge driverless cars and robots.
The country is looking to spend 19.5 billion yen (£139m) on the brand-new computer. It should be able to make 130 quadrillion calculations per second.
The news comes under Japans government policy to keep up with South Korea and China, which are currently home to the world’s best performing machine.
Sources have told Reuters that the country’s engineers are looking to begin building as early as next year.
The new computer will be 130 petaflops which would be China’s Sunway Taihulight which is capable of 93 petaflops.
Satoshi Sekiguchi, from Japan’s National Institute of Advanced Industrial Science and Technology, told Sky News: “As far as we know, there is nothing out there that is as fast,”
The Prime Minister of Japan, Shinzo Abe, wants companies and politicians to work closely so that Japan can win in the areas of artificial intelligence.
