Toyoda Gosei Invests in Helical Fusion, a Startup for Clean Nuclear Fusion Energy

KIYOSU, Japan--(BUSINESS WIRE)--Toyoda Gosei Co., Ltd. (TOKYO:7282) has invested in Helical Fusion Co., Ltd. in July 2025, which aims to achieve practical nuclear fusion power generation as a promising energy source for the future.

Nuclear fusion is a nuclear reaction where high power is generated without emitting CO₂. It is allegedly more controllable compared to nuclear fission because the reaction can be stopped quickly by ceasing to supply fuel. Deuterium and tritium for the fuel are also abundant in seawater. International competition is therefore intense in developing nuclear fusion as a way to fundamentally solve the world’s energy problem.

Helical Fusion is a startup that was established based on research findings at the National Institute for Fusion Science. With its strengths in engineering technology for the nuclear fusion reactors key to power generation, the company aims its social implementation.

As this new power generation is expected to grow, Toyoda Gosei invested in Helical Fusion with a view to exploring fields where the company can leverage its technology and increase its knowledge. This investment is one of the venture investments Toyoda Gosei is making as part of efforts to explore and enter new business fields.
