Helix HARUKA

Helix HARUKA is Helical Fusion’s intermediate demonstration device. It is intended to validate technologies before the planned Helix KANATA power-producing unit. The published program distinguishes a first phase for magnet testing from a second phase for integrated demonstration. HARUKA’s second phase is explicitly described as having no power generation, an important distinction when comparing it with proposed fusion power plants.

Phase 1 is located in dedicated joint-research space on the National Institute for Fusion Science campus in Toki, Gifu. Its purpose is to assemble and current-test a non-planar helical high-temperature superconducting magnet; the announced target is energization testing in 2027. Phase 2 would bring together magnets, blanket/divertor technologies and sustained high-temperature plasma operation. Its location was not disclosed in the cited site announcement, and the Phase 1 address should not be assigned to every later phase. Helical Fusion: HARUKA Phase 1 construction site

Helical Fusion reported completion with RYOKI TOOL of ten coil-case parts and one prototype breeding-blanket component. These provide tangible manufacturing milestones for the hardware program. They do not demonstrate the performance of a fully assembled device, a self-sufficient fuel cycle or net-electric operation. For overseas readers, HARUKA is a useful example of how a reactor-development company connects precision manufacturing to an integrated test platform. Its success will depend on subsequent assembly, testing and validation under the conditions required by the next stage. Helical Fusion: HARUKA components manufactured with RYOKI TOOL
