What Kitac does

Kitac (株式会社キタック) is a comprehensive construction consulting firm founded on February 1, 1973, and headquartered at 新光町10番地2 in Niigata City, Niigata Prefecture, Japan. The firm provides integrated consulting across four technical themes — construction (geological surveys, civil engineering design), disaster prevention, infrastructure maintenance, and environmental services — and serves national, prefectural, and municipal government clients with regional offices in Tokyo, Nagaoka, Yamagata, and Fukushima. Customers include the MLIT Hokuriku Regional Development Bureau and its sediment control and river offices, Niigata Prefecture and its regional development bureaus, Niigata City, and Tokyo Metropolitan Government.

Kitac generates revenue primarily through professional services engagements procured via public tenders, with pricing not publicly disclosed. The firm transitioned to consolidated financial reporting in 2021 and is listed on the Tokyo Stock Exchange Standard Market. In December 2023, Masako Nakayama became Representative Director and President, succeeding Teruya Nakayama who became Chairman. Kitac holds ISO 9001 and ISO 27001 certifications and has accumulated more than 15 government commendations between 2021 and 2025, including a JICA Director General Award and Mongolia's North Star Medal for international work.

In 2025, Kitac launched its first proprietary technology product, COREMIE, a trademarked boring core photography system with standardized LED lighting and automated image stitching that achieves approximately 90% work reduction. An add-on module, COREMIE AI Pro, applies Transformer-based image analysis for automated soil classification, with output compliant to national column-chart XML standards. COREMIE was registered in 2025D206 under Niigata Prefecture's Made in Niigata New Technology system. The firm also announced a business partnership with IDA Corporation in November 2025 and a capital reduction in March 2026. Kitac operates community-engagement facilities (Chisoku Group cafe, art museum, and care house) at its headquarters building.
