HAZAMA ANDO Signs MoU with Helical Fusion for Fusion Pilot Plant Construction

Helical Fusion Co., Ltd. (“Helical Fusion”), a Japan-based fusion energy startup developing fusion power plants, and HAZAMA ANDO CORPORATION (“HAZAMA ANDO”), a long-established Japanese general contractor, recently announced that HAZAMA ANDO has become an Official Partner in the Helix Program, Helical Fusion’s commercial fusion initiative. The two companies have also signed a memorandum of understanding (“MoU”) to collaborate toward the construction of Helix KANATA, Helical Fusion’s Fusion Pilot Plant targeted for the 2030s.

Fusion energy has the potential to shift the foundation of energy from natural resources to advanced technology by reproducing, on Earth, the same principle that powers the stars. It is expected to create a major new industry while providing a long-term solution to global energy challenges. Helical Fusion is advancing the Helical Stellarator approach, a magnetic-confinement fusion concept supported by approximately 70 years of research at national universities and public research institutes. The approach is considered well suited to commercial power plants because it offers a clear pathway to continuous operation, net electricity generation, and maintainability.

Helical Fusion established the Official Partner framework in April 2026 to accelerate the Helix Program, its roadmap to realize commercially viable fusion power in the 2030s. The next decade will be a critical period in which core technologies and industrial capabilities for future fusion power plants move from research and development toward integrated engineering and construction.

HAZAMA ANDO has delivered construction projects for power-related facilities and other social infrastructure that support stable electricity supply. Through this MoU, the two companies will examine construction-related requirements and project execution approaches for future fusion power facilities, including “Helix KANATA”, the Fusion Pilot Plant. HAZAMA ANDO’s participation as an Official Partner is expected to strengthen the industrial foundation.

Under the shared message “Creating a New Sun for Our Horizon,” Helical Fusion and HAZAMA ANDO will work together to build the foundations of a fusion energy industry.
