Message from the New President

Representative President Jun Tanaga

For 30 years since its establishment, HOUSEI has addressed customers' IT challenges with self-contained solutions, from upstream to downstream in software development, including recent cloud environment construction. What we have valued is not just technology. It is our stance to think with our customers, stand by them, and unfailingly achieve their desired goals. We believe that this 'power to accompany' and 'ability to deliver' are HOUSEI's unchanging value and the foundation for our growth. Meanwhile, with the rapid evolution of generative AI, the nature of IT services is facing a major turning point. How development proceeds and the values demanded are undergoing changes that are not mere extensions of the past. Under the philosophy of 'Embracing Change and Continuous Innovation,' we intend to positively accept these changes and create new value that aligns with the times. Based on our cultivated full-stack technical capabilities and the ability to bring our customers' visions to fruition, we aim to be an IT partner that continues to grow with our customers even in this era of change.
