Japan to Build World's First Zetta-Class Supercomputer by 2030

The $750M Fugaku Next aims to achieve unprecedented speeds, but faces significant energy challenges.

Fugaku Next is projected to reach zettaFLOPS, performing one sextillion calculations per second, a thousand times faster than current top supercomputers.
Japan's Ministry of Education, Culture, Sports, Science and Technology (MEXT) is leading the project with an estimated budget of over $750 million.
The supercomputer will be developed by RIKEN and Fujitsu, leveraging custom-designed CPUs and high-bandwidth memory systems.
Energy efficiency remains a major hurdle, with estimates suggesting the need for power equivalent to 21 nuclear power plants.
Fugaku Next aims to advance fields such as AI, climate modeling, medical research, and astrophysics, significantly boosting Japan's computational capabilities.
