(Representative Director and CEO of TriIs Inc.)

As a country frequently hit by natural disasters, Japan is facing increasingly aging infrastructure mostly built during the period of high economic growth, with equipment renovation, extension of service life, and the effective utilization of existing stock looming as urgent challenges. On the other hand, as environmental issues such as global warming become apparent, it is imperative to conserve the global environment and create a sustainable society. Since its establishment, Crearia has consistently been engaged in the maintenance and design of river-related infrastructure. Taking full advantage of our accumulated know-how and always improving our special technical expertise in water, we will continue to meet ever-changing social needs. Furthermore, turning our eyes toward neighboring regions and upstream regions in addition to our existing business fields, Crearia will make efforts to evolve into a company actively committed to environmental conservation and restoration. Our aim is to be a company with a distinctive presence with the most advanced technical skills and customer support even though small in size in the construction consulting industry.
