Japan plans to build the world's first "zeta-class" supercomputer, a machine 1,000 times faster than today's most powerful ones. This supercomputer, estimated to cost over USD 750m, will help Japan stay competitive in AI development. The Ministry of Education, Culture, Sports, Science, and Technology announced plans on 28 August for this machine, which could reach speeds on a petaflops scale. This unprecedented speed would allow it to perform one sextillion (1 followed by 21 zeros) calculations per second, surpassing current supercomputers' exaFLOPS speeds (one quintillion calculations per second). The supercomputer is expected to be fully operational by 2030.

The proposed supercomputer is being touted as the successor to Japan's Fugaku supercomputer (0.44 exaFLOPS), which previously held the title of the world's fastest supercomputer until it was dethroned in 2022 by the U.S.'s Frontier supercomputer (1.2 exaFLOPS) at Oak Ridge National Laboratory in Tennessee. Fugaku is currently considered the fourth most powerful supercomputer in the world.
Japan to start building 1st 'zeta-class' supercomputer in 2025, 1,000 times more powerful than today's fastest machines
Japan's new state-of-the-art supercomputer, which is due to cost more than $750 million to build, is set to turn on by 2030.

スパコン富岳後継、AI計算で世界初ゼタ級へ25年開発始動 - 日本経済新聞
国の基幹スーパーコンピューター「富岳」の後継機の開発が2025年に始まる。文部科学省は初年度の開発・整備費として、25年度予算案の概算要求に約42億円を盛り込む。人工知能(AI)を活用した科学研究の発展に対応するため、ポスト富岳ではAI向けの計算で世界初の「ゼタ(ゼタは1兆の10億倍)級」と呼ばれる高速性能の実現を目指す。国費投入1100億円以上に開発費用の総額のうち、国費は1100億円以上
