Advancing as one: academia and industry united
“Fusion energy is not just a dream. But if we don’t act now, we may miss our chance.”
Driven by this belief, researchers and engineers have come together—devoting their efforts to make fusion energy a reality. Crossing the boundaries between academia and industry, we are pooling world-class expertise and technology to take on the challenge of demonstrating fusion-based power generation—a first for Japan, and for the world.
