Cyest to tackle two critical social issues in Japan with one solution.


Long before the most recent meltdown of two nuclear plants following the Great East Japan earthquake, Japan has been struggling to find sustainable sources for its huge energy consumption. Pressure from the local general public to lower dependency on nuclear power has urged both the state and private sectors to look for renewable energy alternatives.

The Project

Seeing the need to improve Japan’s energy self-sufficiency, Cyest co-founder Yoshiaki Kitamura took the opportunity to bring together a team of retired former executives to create a new business line that builds and invests in new renewable energy utilities, including solar panels, wind turbines and biomass plants. The company, named Cyest Energy, has now completed 14 projects all over Japan by 2019 March, generating a total of 26.4 MW. More projects are also under development.

As implied in the name Cy – as in Cycle and est – as in Best, Cyest Energy serves to optimize the resources of human talent (retired industry experts) and natural energy supply for the society.

The People

Cyest Energy team consists of Kitamura and three industry experts.

  • Mr. Matsunaga – Former Finance Manager at Goldman Sachs Realty Japan Limited, former VP at MUFJ/Investment Banking and most recently Head of Solar Energy IPP at Hanwha Q Cells Japan.
  • Mr. Kasahara – Former Deputy Head of Design and Planning Department at Taisei Corporation (one of two Japanese giant general contractors.)
  • Mr. Kazusa – Former Managing Director of Honda Brazil, the Honda F1 business, former President of Honda Hero India and Honda Soltech Japan.

Our experts work with us on a hands-on advisory basis, which enables us to start small while leveraging on top class industrial know-how.
