Striving to Be the Most Appreciated Company in the IT Industry through “IT” × “OT” × “Omotenashi (Japanese hospitality spirit)”
Quest Corporation was founded in 1965, at the dawn of the information services industry, and proudly celebrates its 60th anniversary in 2025.
We would like to express our sincere gratitude to all our stakeholders for their unwavering support and cooperation over the years.
Since our founding, we have provided consulting, system development, IT infrastructure construction, and operations and maintenance services to a diverse range of industries, including manufacturing (notably semiconductors), financial institutions, electric power companies, and railway groups.
By combining the expertise and technical skills cultivated in each of these fields, we remain committed to always being close to our customers, refining our technology, and consistently delivering services that exceed expectations.
The "sincere spirit of inquiry" and the "customer-oriented approach" nurtured over the past 60 years form the foundation of Quest’s corporate philosophy.
These values have been passed down as the very soul of our dedicated employees who relentlessly devote themselves to their work.
Going forward, we will continue to contribute to solving social issues together with our customers, business partners, and alliance partners, pursuing a more prosperous society and sustainable growth.
With the fusion of IT (Information Technology) × OT (Operational Technology) × Omotenashi (Japanese hospitality spirit), we strive to become the company in the IT industry that hears “A-RI-GA-TO-U”(=“Thank you”) the most.
We humbly ask for your continued understanding and support in the years to come.
