METI's FY2025 supplementary fund expects to distribute the total across multiple operators by February 2029; Helical cleared the first hurdle but formal selection and individual grant amounts remain to be announced.
Japan's Ministry of Economy, Trade and Industry has conditionally approved Helical as a project operator under its FY2025 supplementary grant for fusion power generation demonstration, a program that expects to distribute roughly ¥60 billion (~$370 million) across selected operators by the end of February 2029.

Mainstream fusion, including the ITER project under construction in France, is built around tokamaks, reactor shapes that look like a donut. A stellarator twists that donut into a figure-8, and the National Institute for Fusion Science, where Helical's underlying research was conducted, argues the shape addresses coil-density asymmetries baked into the tokamak approach.

Helical, founded in October 2021, is one of several operators conditionally approved across a multi-bet portfolio. Formal selection and individual grant amounts remain to be announced. (Helical via PR Times) (Mainichi)
The program's mid-2020s targets: individual demonstrations of the high-temperature superconducting magnet and the blanket/divertor. Integrated demonstrations are planned for the 2030s using the demo device Helix HARUKA, with a follow-on machine, Helix KANATA, described by the company as the "world's first practical fusion power generation device," a stated target, not an achieved one.

Helical's three commercial-viability tests: steady-state operation, net electricity output, and regular, efficient component maintenance. The 2030s demos are designed to find out whether the geometry passes them.
