LehmanSoft Japan
LehmanSoft Japan is a Tokyo-based energy storage and renewable energy technology firm that pivoted from financial software development into the energy sector.
Profile
Develops and operates battery storage systems that help balance Japan's electricity grid as it adopts more renewable energy.
LehmanSoft Japan is a Tokyo-based energy storage and renewable energy technology firm that pivoted from financial software development into the energy sector. Originally founded as a developer of trading systems for financial markets, the company leveraged its algorithmic trading expertise to enter Japan's rapidly growing battery energy storage system (BESS) market in the early 2020s. Their first grid-scale project, a 2MW/8.1MWh facility in Saitama Prefecture, came online in December 2025, marking their transition from software to physical energy infrastructure.
The company now operates three core business lines: battery storage aggregation services, energy management systems (EMS), and turnkey BESS project development for investors. They position themselves as a bridge between Japan's financial markets and its renewable energy transition, applying market-making concepts to electricity trading. While still small compared to domestic players like Sumitomo Electric or Softbank's new battery division, LehmanSoft has carved out a niche by combining energy market operations with their financial technology roots. The company appears to be capitalizing on Japan's GX 2040 Vision, which earmarked ¥20 trillion for green transition projects including energy storage.
