TDK generates $10.1 billion a year by manufacturing objects most people have never seen — ceramic capacitors thinner than a human hair, magnetic cores the size of a fingernail, lithium-polymer cells sealed in flexible foil pouches. The company controls roughly 103,000 employees and operates factories on four continents, yet its most important competitive asset sits at the molecular level: proprietary barium titanate dielectric layers sintered at temperatures above 1,000 degrees Celsius without cracking. The 2005 acquisition of Amperex Technology Limited turned out to be one of the most consequential moves in consumer electronics supply history. ATL became the standard-bearer for lithium-polymer batteries inside premium smartphones and wearables, embedding TDK's chemistry into devices sold by companies that would never publicly acknowledge a single-source dependency. By 2024, that bet generated a meaningful portion of TDK's energy segment revenue. Revenue peaked at $11.5 billion in fiscal 2022 and contracted to $10.1 billion by 2024, reflecting an inventory correction in consumer electronics and a slowdown in electric vehicle adoption rates. Operating margins compressed under pricing pressure in standard passive components — the segment where competitors from mainland China have been closing the quality gap for a decade. What the revenue decline obscures is TDK's deeper trajectory: the company has spent thirty years moving from commodity ferrite cores toward system-level sensor modules that combine MEMS accelerometers, gyroscopes, and pressure sensors into integrated units. The 2017 acquisition of InvenSense and Micronas accelerated that shift. The result is a company whose most defensible business lines require capabilities that took TDK four decades to build — and that a new entrant cannot replicate with capital alone.
President and Chief Executive Officer
Kikuchi assumed the role of CEO in 2023, continuing the aggressive execution of the company’s strategic pivot toward automotive, industrial, and next-generation energy storage solutions, focusing on maximizing shareholder value through disciplined capital allocation and the development of advanced solid-state battery technologies.
President and Chief Executive Officer
Ishitsuka led the company through its most transformative period, executing the aggressive expansion of the ATL battery operations, orchestrating the integration of the InvenSense and Micronas sensor acquisitions, and fundamentally changing the company's business model to focus on high-reliability automotive and industrial electronics.
As companies like Texas Instruments, Analog Devices, and Infineon develop highly integrated power modules and system-in-package (SiP) solutions that combine silicon logic with embedded passives, they threaten to eliminate the need for discrete MLCCs and inductors on the printed circuit board, potentially shrinking the total addressable market for TDK's traditional passive components. The second major challenge is the extreme geopolitical and supply chain risks associated with the raw materials required for its Energy Business, specifically lithium, cobalt, nickel, and rare earth elements. The third critical challenge is the intense cyclicality and rapid technological obsolescence inherent in the consumer electronics market, which historically has been the primary revenue driver for the Energy Business. Finally, the company faces a persistent challenge in managing the extreme foreign exchange volatility that impacts its financial reporting.
The company's founding philosophy was centered on the radical idea of domestic industrial self-sufficiency, dictating that Japan could and must design and manufacture its own advanced electronic materials, tailored specifically to the unique operational challenges of the nation's rapidly modernizing infrastructure. The pivotal moment in the company's early history occurred during the devastation of World War II, when TDK's manufacturing facilities were severely damaged, and the company faced the existential threat of total collapse.
TDK has had a relatively stable line of presidents and CEOs since founding in 1935, each typically rising through internal materials and engineering ranks. Kenji Kawai served as the founding president from 1935 and led the company through its early industrial decades. Successive Japanese presidents oversaw the expansion into recording media, the global brand build of the cassette era, and the diversification into components. In the 2000s and 2010s the leadership transition was managed through structured handovers, with Hajime Sawabe serving as president from 1998 and as chairman afterward. Takehiro Kamigama became president and CEO in June 2006, leading TDK through the EPCOS acquisition in 2008, the exit from recording media in 2007, and the early growth of ATL battery sales. Shigenao Ishiguro succeeded him as president and CEO in June 2016, overseeing the InvenSense acquisition in 2017. Noboru Saito became president and CEO in June 2022, continuing TDK's strategic emphasis on sensors, batteries, and automotive electronics. The CEO succession has consistently favored internal candidates with materials and engineering backgrounds rather than external hires.
Noboru Saito became president and CEO of TDK Corporation in June 2022, succeeding Shigenao Ishiguro. Saito is a long-serving TDK insider who joined the company in 1985 and rose through engineering and management roles, including assignments in the magnetic application products business and in corporate strategy. Prior to becoming CEO he served as senior vice president and as head of key product groups, giving him broad operational experience across components and energy. Saito's strategic agenda has emphasized four priorities. First, expanding the company's exposure to electric vehicles and advanced driver-assistance systems through higher-content sensors, capacitors, and DC-DC components. Second, continuing the long-term investment in lithium-ion battery capacity at ATL, while developing solid-state and other next-generation battery technology. Third, deepening the sensor portfolio inherited from InvenSense and Micronas with emphasis on industrial and automotive applications. Fourth, sustaining roughly 7 to 8 percent R&D intensity to defend technology leadership. Saito has publicly framed TDK's positioning around the energy transition, electrification of vehicles, and the data-driven society, drawing a line from the company's 1935 ferrite origins to its modern role as a supplier of components for smartphones, cars, and renewable-energy infrastructure.
Takehiro Kamigama served as president and CEO of TDK from June 2006 to June 2016 and led the company through one of the most strategically active decades in its history. Under his leadership TDK completed the 2007 exit from consumer recording media, ending a half-century in cassettes and tape that had defined the company's consumer brand. The same year he oversaw the integration of ATL battery operations acquired in 2005 as smartphone demand began to accelerate. In 2008 he led TDK's largest acquisition to that point, the roughly 1.18 billion euro purchase of EPCOS, transforming the company into a global passive-components leader with major European footprint. Kamigama also navigated the 2011 Great East Japan Earthquake, which damaged several TDK plants, and managed the subsequent supply-chain recovery. He pushed restructuring of legacy product lines while increasing investment in batteries and sensors. By the time he handed over to Shigenao Ishiguro in 2016, TDK's revenue mix had shifted decisively toward components and energy, and ATL had become the single largest growth engine. Kamigama later served as chairman of TDK, continuing to influence strategic direction at the board level.
Shigenao Ishiguro served as president and CEO of TDK Corporation from June 2016 to June 2022, a six-year tenure that emphasized the company's transformation into a sensor and battery powerhouse. Ishiguro joined TDK in 1981 and had extensive experience in passive components and in corporate management before his appointment. His most prominent strategic move was the 2017 acquisition of InvenSense for approximately $1.3 billion, which gave TDK a leading position in MEMS motion sensors and microphones for smartphones, wearables, and automotive applications. Under his leadership TDK also continued substantial investment in ATL battery capacity to meet rising smartphone and emerging electric-vehicle demand, with multiple new plants built in China and abroad. Ishiguro guided the company through the 2018 to 2019 trade tensions and supply-chain disruptions as well as the 2020 to 2021 COVID-19 pandemic period, during which demand for electronics components surged. He emphasized a strategic narrative around the energy transition, electrification, and sensor-driven applications, framing TDK as a beneficiary of the structural shifts in mobility and connectivity. He handed over to Noboru Saito in June 2022 and continued to serve on the TDK board.
