Our history of IT service
Company director used to work for major Japanese telecommunication companies.
While providing IT support services for global companies, we have conducted interviews with over 1,000 engineers, hired many of them, and collaborated with more than 300 companies. This experience has allowed us to refine our approach to IT management. Additionally, we have attended various IT and security seminars to stay updated on industry trends and best practices.
Our experience includes establishing a brand-new office in Tokyo with only a few employees, building its IT infrastructure from the ground up.
Another example of our expertise is handling company separations due to M&A. This involved exporting users and PCs from the Active Directory server and importing them into a new server hosted on a local virtual machine. We also integrated Microsoft 365 single sign-on with both on-premises and Azure AD servers to enhance the user experience. Furthermore, we implemented a cost-effective solution using Synology NAS for online virtual machine backups, enabling quick backup and recovery when needed.
Our history of solar service
We have developed total of 12 solar energy sites in Japan (as of year 2025).
We began by purchasing land and hiring local electrical wiring companies, gradually gaining expertise in developing solar energy plants. To ensure quality and cost-effectiveness, we visited factories in China to inspect and negotiate the purchase of solar panels. Additionally, we tested various supply chains to optimize the balance between cost and delivery time.
We have hired various engineers and workers to improve our service. We also have spent significant amount of time designing, reducing risks, and paralleling tasks.
