Astemo, Ltd. (日立Astemo, Hitachi Astemo Kabushiki-Gaisha) is a global automotive components manufacturer headquartered in Otemachi, Chiyoda-ku, Tokyo, Japan.

The company name was changed from Hitachi Astemo, Ltd. to Astemo, Ltd. on April 1, 2025.[1]

Overview

[edit]

Hitachi Astemo was established in January 2021 as a global automotive components manufacturer through the business merger of Hitachi Automotive Systems, Keihin Corporation, Showa Corporation and Nissin Kogyo.[2][3]

The name "Astemo" stands for "Advanced Sustainable Technologies for Mobility", reflecting the company's focus on technologies related to connected, autonomous, shared and electric mobility. Astemo develops automotive technologies aligned with the industry trends of connectivity, autonomous systems and electrification, with a focus on both passenger and motorcycle applications.[4][5]

Astemo's ownership structure includes major stakes from both Hitachi, Ltd. and Honda Motor Co., Ltd., each holding 40%, with JIC Capital holding the remaining 20%. While Astemo includes former Honda-affiliated parts manufacturers, it also maintains business relationships with Nissan Motor Co., reflecting Hitachi's historical ties to the Nissan Group.[3][4]

Strategic Direction and Market Position

[edit]

Astemo has expanded its research and development activities in electric powertrains, advanced driver-assistance systems, and in-vehicle software. These efforts support its strategic focus on electrification and autonomous mobility. The company has also pursued partnerships and vertical integration to address industry competition and supply chain challenges.[6]

In December 2024, the Government of Cantabria awarded the Hitachi Astemo Buelna plant a €1 million grant through SODERCAN’s competitive programme for major industrial competitiveness projects. The funding supports a €5 million experimental development project focused on advanced braking systems, to be completed over 18 months. This initiative underlines the region’s strategic support for automotive innovation and sustainability efforts.[7]

Technology and Innovation

[edit]

Astemo develops components for electric and autonomous vehicles, with a focus on integration of key systems such as power control units, motors, inverters, and software-defined vehicle platforms. The company also emphasizes model-based systems engineering and virtual validation to shorten development timelines and reduce prototyping costs.[5] In 2023, Astemo announced a ¥15.3 billion (~US $100 million) expansion of its Berea, Kentucky plant to support its electrification business.[8]

In July 2025, Astemo announced a £100 million investment in its Horwich manufacturing facility in Bolton, Greater Manchester. The project will establish a new production line dedicated to electric vehicle (EV) inverters, making the site the only facility in the United Kingdom with this production capability.[9][10]
