According to a recent report by the Nikkan Kogyo Shimbun, Kioxia (formerly Toshiba Storage) plans to invest up to 2 trillion yen (approximately US$18.38 billion) to build a new 3D NAND flash memory plant at the Kitakami plant in Iwate Prefecture, Japan, and will start operations in 2023.

Kioxia’s new plant in Kitakami, named K2, will break ground around the spring of 2022 and is expected to complete the construction in the spring of 2023, and will start the production of 3D NAND flash memory a few months after completion.

According to Kioxia, the K2 plant will mainly use the existing equipment of its Yokkaichi plant. In the 2 trillion yen investment, in addition to the construction cost of the K2 plant and ancillary facilities, it also includes the equipment supplementary cost of the Yokkaichi plant. In terms of equipment investment, Kioxia may share costs with its partner Western Digital.

In addition, the new plant of Kioxia Yokkaichi plant is currently under construction. The project is divided into two phases. The first phase is scheduled to be completed in the spring of 2022.
