Today, Toshiba Corporation (Toshiba) has decided to transfer all shares of Toshiba Materials Co., Ltd. (Toshiba Materials), a wholly owned subsidiary of Toshiba, to Niterra Co., Ltd. (Niterra), and has concluded a share transfer agreement with Niterra, with the aim of completing the transfer by May 30, 2025 after going through the necessary procedures.

Toshiba Materials’ origins are in Toshiba’s specialty materials business, and the company has long applied its unique technologies to functional materials and components that meet evolving industry needs and changing times. These have included metal materials for cathode ray tubes, phosphor materials used in fluorescent lamps, color TVs, and medical equipment, and silicon nitride components used in aircraft and electric vehicles. The company is particularly known for its silicon nitride balls, a fine ceramic product, which have won a high share in the global market of ball bearings for electric vehicles, machine tools, wind power generators, railway vehicles, and other applications that require high-speed rotation and high resistance to corrosion. In addition, demand for its silicon nitride ceramic substrates used in power semiconductors and other applications is expected to grow.

Niterra leverages core competencies, including in ceramic material technology, to explore new fields, with the major strategic objective of strengthening its core internal combustion engine business while simultaneously expanding the scale of its non-internal combustion engine businesses. The company is doing this by focusing on four fields: Environment & Energy; Mobility; Medical; and Communication, and is expanding its business and developing new businesses in these areas. 

These are all areas where Toshiba Materials also has strong capabilities in material design and, processes and product application technologies, and synergies can be expected from the integration of Niterra and Toshiba Materials’ ceramic technologies, expansion of the global customer base, and the enhancement of support systems. Toshiba has determined that Niterra is the best partner for Toshiba Materials, with the resources required to maximize the potential of Toshiba Materials, and that pursuing synergies under Niterra will enhance Toshiba Materials' corporate value.
