Japan has accomplished a feat that feels like science fiction researchers have achieved a record-breaking internet speed of 1.02 petabits per second. At that speed, massive libraries of music, movies, and games could be downloaded almost instantly.
This groundbreaking achievement, made possible using existing fiber optic technology, has the potential to revolutionize global data sharing, cloud computing, and the use of artificial intelligence.
With speeds this fast, you could stream millions of 8K videos simultaneously or download the entire Steam game library in an instant. That’s the power of the world’s fastest internet now in Japan.
Japan demonstrated the future last month. Imagine being able to download all of Netflix's content faster than it takes to launch the app, and it's going to translate into a reality.
By sending data at an astounding 1.02 petabits per second in June 2025, researchers at Japan's National Institute of Information and Communications Technology (NICT) subtly broke the world record for internet speed. 1,020,000 gigabits per second, that is.
How did Japan achieve it?
It was more than a lab trick. NICT transmitted data using standard-sized fiber optic cables, the same type that is used globally, but with four cores and more than 50 distinct light wavelengths. Even more amazing is the fact that they were able to sustain this crazy speed for 51.7 kilometers, which makes it practical for infrastructure in the real world.
What can this speed actually do?
This type of internet speed could enable instantaneous global AI processing, connecting data centers across continents as if they were on the same local network, given the demands of cloud computing, generative AI, autonomous vehicles, and real-time translation tools, which all require massive data throughput.
You can download all of the games available on Steam in just a moment. You could theoretically download every game ever made, from Counter-Strike 2 to Baldur's Gate 3, in less than 10 seconds with Japan's new internet speed.
Ten million 8K ultra-HD videos could be streamed at once at that speed. This would equate to offering a free, high-quality movie stream to every individual in Tokyo and New York City.
This also implies that you could download 1,27,500 years of music in a second, and backup all of Wikipedia's content 10,000 times in a second.
Will home users get this speed soon?
Unfortunately, not anytime soon. Terabit speeds have not yet been attained by consumer internet. However, governments, data center operators, and telecom behemoths are taking notice.
Japan's recent success could serve as a model for 6G networks, national broadband backbones, and the next generation of underwater cables.
