US projects become key opportunity for Japan’s nuclear industry
Japanese nuclear industry companies are looking to US projects for growth as new nuclear plant construction in Japan remains uncertain.
A 2025 Japan-US government agreement set out 80 trillion yen in investment in the United States, with up to 30 trillion yen for nuclear power.
Japanese companies aim to compete with US and European firms by developing next-generation reactors designed to improve safety and costs.
One example is Japan Steel Works’ Muroran plant in Hokkaido, which has supplied difficult-to-make parts for nuclear plants in Japan and overseas.
The plant is making its first major investment in 15 years, as Muroran sees renewed activity.
US business could help sustain Japan’s nuclear suppliers while domestic opportunities remain limited.
The companies’ next challenge is to win work in the US market against established competitors.
