TOKYO, Dec 30 (News On Japan) –
As international uncertainty continues to develop, Japan’s digital parts business has been quietly strengthening its presence on the world stage.
A better have a look at applied sciences acknowledged by Apple reveals Japan’s present place as a essential hub within the international provide chain.
Once once more this 12 months, Japan was abuzz with pleasure over Apple’s newest product launch.
The iPhone 17, launched in September 2025, drew consideration for its new options and design, however what lies contained in the machine stays largely unknown to most customers.
At a warehouse in Tokyo, an organization specializing within the teardown and evaluation of digital units disassembles every part from private computer systems to gaming consoles on the request of company shoppers, compiling detailed studies.
“This is the iPhone 17 Pro and Air,” mentioned Kashio Nansho, CEO of Fomalhaut Techno Solutions.
The firm disassembled the newest iPhone instantly after its launch. What they discovered was placing.
“In the case of the iPhone, most of the components are made in Japan. Smartphones simply cannot be built without Japan,” Kashio mentioned.
Nearly 1,300 Japanese-made components are used within the newest iPhone, underscoring the nation’s overwhelming presence within the machine.
“With concerns recently raised over tensions surrounding Taiwan, if anything were to happen in China, Japan’s position as a supplier of electronic components would become even more important,” Kashio added.
Among essentially the most distinguished parts is a sensor wherein Japan holds a commanding lead.
“Japan is especially strong in camera-related components. One key example is TDK’s TMR, or tunneling magnetoresistance sensor,” Kashio mentioned.
TMR sensors play an important function in digicam autofocus and picture stabilization. They are produced by TDK, certainly one of Japan’s main digital parts producers.
At the World Athletics Championships held in Tokyo in September 2025, the TDK brand was seen on the athletes’ chests, a reminder of the corporate’s rising international presence.
That similar month, TDK President Noboru Saito was photographed introducing the corporate’s know-how to Apple CEO Tim Cook. The assembly happened at Apple’s confidential analysis facility in Yokohama, the place 4 Japanese producers have been invited to showcase their applied sciences. Cook reportedly praised every of them immediately.
TDK, as soon as finest recognized for cassette tapes, has remodeled itself over the a long time. The firm’s resurgence has drawn renewed international consideration.
Inside a TDK manufacturing facility in Nagano Prefecture, tv cameras have been allowed in for the primary time. After passing by way of air showers and strict cleanliness controls, solely rigorously screened personnel are permitted contained in the cleanroom.
While most manufacturing processes stay confidential, one machine used to form essential parts was proven.
“This device forms the essential patterns for TMR sensors,” mentioned Noriyuki Ito, common supervisor of TDK’s TMR sensor manufacturing division.
Through a number of precision processes, the parts are lowered to a measurement smaller than a grain of rice—so small they will barely be seen on a fingertip.
“All of our most advanced technology and passion are packed into something this small,” mentioned Hayato Miyashita, head of TDK’s TMR sensor enterprise. “That is our strength.”
Apple has extremely valued this focus of cutting-edge know-how.
TDK’s rising profile can be mirrored in rising expectations from the United States. Commerce Secretary Gina Raimondo has said that TDK produces digital parts and energy modules important to AI infrastructure valued at roughly 250 billion {dollars}, signaling robust curiosity in additional funding.
TDK’s progress has been pushed by fixed adaptation.
“Society is constantly transforming, so we must continue to transform as well,” mentioned President Saito.
Founded in 1935 to commercialize ferrite, a magnetic materials nicely suited to electronics, the corporate has repeatedly shifted its core merchandise to match altering occasions. Today, smartphone parts comparable to TMR sensors are driving its enlargement.
Another key to its success has been aggressive acquisitions.
“We have been pursuing M&A for 40 years, but especially over the past decade, many new partners have joined our group,” Saito mentioned.
One notable acquisition was a Chinese battery maker bought in 2005 for round 10 billion yen. That firm now instructions roughly 60 % of the worldwide marketplace for smartphone batteries.
Through such acquisitions, TDK has expanded to 141 group firms worldwide. Of its greater than 105,000 staff, about 90 % are non-Japanese nationals.
Even as a worldwide enterprise, TDK continues to carry executives from all over the world collectively for coaching packages aimed toward sharing frequent values.
At the core of these values is what the corporate calls the “ferrite tree,” an idea rooted in its foundational experience in magnetic supplies.
“From magnetic materials, our business has branched out like a tree into cassette tapes and many other products,” Saito mentioned. “That evolution defines who we are today.”
By dominating specialised niches fairly than mass markets, Japan’s producers proceed to show that small parts can carry huge international affect.
