▶ German companies choosing Japan as Asia manufacturing hub: survey
22 Sep, 2025

Source : AHK Japan
A recent survey by the German Chamber of Commerce and Industry in Japan (AHK Japan) shows that German companies increasingly view Japan as a strategic manufacturing hub for Asia, not just a sales market. Key attractions include Japan’s economic stability, relative affordability due to the weak yen, strong regulatory environment, and proximity to major Asian markets like ASEAN and China. Out of 730 German companies in Japan, 84 run production or assembly sites. Many have long-standing operations, with 76% producing in Japan for over 20 years, and over half planning expansion. Exports from Japan are primarily sent to ASEAN (41%), China (38%), and North America (29%). Strong Germany-Japan business alignment, supply chain stability, and political risk mitigation are major incentives. However, challenges remain, especially in recruiting skilled labor—cited by 82% of respondents. Despite these hurdles, Japan is seen as a reliable and stable base in an uncertain global environment.

▶ US machine tool tariff probe targets field led by Japan
25 Sep, 2025

Source: Global Trade Atlas
The U.S. has launched a Section 232 investigation into machine tools, industrial robots, and medical equipment to assess whether import restrictions or tariffs are needed. This could significantly impact Japan, the top supplier of machine tools to the U.S., with $1.53 billion in exports in 2023. Japanese companies like Okuma and Olympus warn that tariffs would raise costs and hurt profits, as shifting high-precision production to the U.S. is difficult. The move could also raise manufacturing costs for U.S. companies and contradict efforts to boost domestic industry. Japan also plays a key role in medical equipment, with Olympus dominating the endoscope market, much of which is made in Japan.

Kansai Electric will start decommissioning two units at its oil-fired Gobo Power Station in October, aiming to finish by mid-2026, as part of its shift from fossil fuels to nuclear energy. The company has already restarted all seven nuclear reactors and reduced fossil-fuel use from 59% in 2019 to 39% in 2024. Oil-fired plants, like Gobo, are less efficient and more polluting, though useful for backup. Kansai is also expanding energy storage to support this transition. Japan's broader energy plan aims to cut fossil-fuel power to 30–40% by 2040. Other utilities are also phasing out coal and oil plants.
