Ibisoku's Strengths

  • 1

    Flexible yet bold implementation of ICT,
    DX, AI, and more

    Ever since Ibisoku's establishment in 1973, we have continued to grow as a general construction consultant for improvement and maintenance of social infrastructure and protecting regional safety, and as a general cultural-property consultant that surveys and paves the way to protective operations for the cultural properties that are national assets. With "innovative technical development and diligent pursuit of technology" as the guiding precept of our company, we continue to take up the challenge of myriad forms of technical development for the purpose of gaining new knowledge. In recent years we have also taken on the challenge of implementing information and communication technology (ICT), digital transformation (DX), artificial intelligence (AI), and even practical use of big data. The sophistication and breadth of these technical capabilities are Ibisoku's strengths.
