The official name of the K computer’s successor, formerly known as the post-K, was announced on May 23, 2019, at a press conference in Tokyo. The name is Fugaku, which is another name for Mt. Fuji. The soaring peak of Mt. Fuji implies high level of performance, and its broad base alludes to the expansion of the user base of the post-K. The iconic mountain is well-known in the world, and the name is well-suited for the new flagship supercomputer of Japan.
