Toyota Motor Corp yesterday said it had been hit by a technical glitch forcing it to suspend production at all of its 14 factories in Japan.
The world’s biggest automaker gave no further details on the stoppage, which began yesterday morning, but said it did not appear to be caused by a cyberattack.
The company said the glitch prevented its system from processing orders for parts, resulting in a suspension of a dozen factories or 25 production lines yesterday morning.

The company later halted the afternoon shift of the two other operational factories, suspending all of Toyota’s domestic plants, or 28 production lines.
“We do not believe the problem was caused by a cyberattack,” the company said in a statement. “We will continue to investigate the cause and to restore the system as soon as possible.”
The incident affected only Japanese factories, it added.
It was not immediately clear exactly when normal production might resume.
In the wake of the news, Toyota’s stock fell 0.20 percent to close at ¥2,431.5 in Tokyo trading.
Last year, Toyota suspended all of its domestic factories after a subsidiary was hit by a cyberattack.
The company is one of the biggest in Japan, and its production activities have an outsized impact on the country’s economy.
Toyota is famous for its “just-in-time” production system of providing only small deliveries of necessary parts and other items at various steps of the assembly process.
This practice minimizes costs while improving efficiency, and is studied by other manufacturers and at business schools around the world, but also comes with risks.
The auto titan retained its global top-selling crown for the third year in a row last year, and aims to earn an annual net profit of ¥2.58 trillion (US$17.61 billion) this fiscal year.
Apple Inc has closed in on an agreement with OpenAI to use the start-up’s technology on the iPhone, part of a broader push to bring artificial intelligence (AI) features to its devices, people familiar with the matter said. The two sides have been finalizing terms for a pact to use ChatGPT features in Apple’s iOS 18, the next iPhone operating system, said the people, who asked not to be identified because the situation is private. Apple also has held talks with Alphabet Inc’s Google about licensing its Gemini chatbot. Those discussions have not led to an agreement, but are ongoing. An OpenAI
INSATIABLE: Almost all AI innovators are working with the chipmaker to address the rapidly growing AI-related demand for energy-efficient computing power, the CEO said Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) yesterday reported about 60 percent annual growth in revenue for last month, benefiting from rapidly growing demand for artificial intelligence (AI) and high-performance computing applications. Revenue last month expanded to NT$236.02 billion (US$7.28 billion), compared with NT$147.9 billion in April last year, the second-highest level in company history, TSMC said in a statement. On a monthly basis, revenue surged 20.9 percent, from NT$195.21 billion in March. As AI-related applications continue to show strong growth, TSMC expects revenue to expand about 27.6 percent year-on-year during the current quarter to between US$19.6 billion and US$20.4 billion. That would
‘FULL SUPPORT’: Kumamoto Governor Takashi Kimura said he hopes more companies would settle in the prefecture to create an area similar to Taiwan’s Hsinchu Science Park The newly elected governor of Japan’s Kumamoto Prefecture said he is ready to ensure wide-ranging support to woo Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) to build its third Japanese chip factory there. Concerns of groundwater shortages when TSMC’s two plants begin operations in the prefecture’s Kikuyo have spurred discussions about the possibility of tapping unused dam water, Kumamoto Governor Takashi Kimura said in an interview on Saturday. While Kimura said talks about a third plant have yet to occur, Bloomberg had reported TSMC is already considering its third Japanese fab — also in Kumamoto — which would make more advanced chips. “We are
Huawei Technologies Co’s (華為) latest high-end smartphone features more Chinese suppliers, including a new flash memory chip and an improved chip processor, a teardown analysis showed, pointing to the progress China is making toward technology self-sufficiency. The inside of Huawei’s Pura 70 Pro was examined by online tech repair company iFixit and consultancy TechSearch International, finding components made by Chinese suppliers. The firms also found that the Pura 70 phones run on an advanced processing chipset made by Chinese chip foundry Semiconductor Manufacturing International Corp (SMIC, 中芯) called the Kirin 9010, which is likely a slightly improved version of the advanced chip
