Ohmori focuses on civil engineering work, particularly projects for water and sewer systems.
Residential work accounts for most architectural contracts.
Ohmori has a real estate business too. The company is firmly committed to expanding existing business fields outward and entering entirely new businesses. Contracts at Morimoto are divided largely evenly between civil engineering and architecture. The company has many accomplishments in public-sector projects, mostly for highways. Other strengths are projects for electric and gas utilities and private railways.
