Environment Efforts related to environment
Design the landscape environment
Build a beautiful bridge. Generate bustle on streets. Develop a river where organisms live affluently and people who visit can interact with nature.
Infrastructure businesses which support lifestyles of all people hopefully respect the rich nature, develop things which can be utilized by everyone comfortably, generate interactions, and foster the culture and fascination of the town... Design is to “embody” the value.
A variety of elements such as safety and convenience expected of facilities as well as the will of people engaged in the business, desires of local residents, and wishes conveyed to the next generation are integrated and embodied.
We contribute to the creation of fascinating environments with the power of design so that words like “what a comfortable place” and “what beautiful scenery” can be heard in various places.
Countermeasures against global warming and regional revitalization with new energy
Since the Great East Japan Earthquake, great importance has been placed on the assurance of energy security in various sectors such as the government, local governments, and private companies, strategies to promote regenerative energy represented by the FIT system have been developed, and the domestic power generation discount rate of the regenerative energy reached approx. 17%. Moreover, the promotion of regenerative energy is, pushed by long-term strategies toward the achievement of RE100 of private companies and the Paris Agreement, expected to accelerate further in the future.
Nippon Engineering Consultants has, since the establishment of “New Energy Business Office” in 2014, conducted various considerations of distributed energy systems and hydrogen supply chains as well as hydrogen supply businesses like hydrogen ST by affiliated companies and sales of pure hydrogen fuel cells. We are going to promote various businesses related to the regenerative energy and keep on making efforts toward the solution of social issues like global warming countermeasures by CO2 reduction and regional revitalization with regenerative energy.
Seiryu Power Energy, an affiliated company of Nippon Engineering Consultants, developed G-FORCE-X, the system that produces and stores green hydrogen with power generated by woody biomass power generation and solar power generation, and supplies it as power and heat when necessary.
In recent years, an increasing number of local governments have expressed their willingness to make efforts toward virtually zero CO2 emission by 2050, and the technology developments will contribute to the realization of decarbonized society and regional resource recycling society.
[Contribution to the promotion of CCS technologies]
“Carbon neutral”, which means prevention of increase in the carbon dioxide (hereafter CO2) concentration that causes global warming, has become a key word for countries to collaborate in developing countermeasures.
Efforts to demonstrate and consider Carbon dioxide Capture and Storage (hereafter CCS) technologies have been made also in Japan based on the recognition of necessity of “CO2 recovery and storage” technologies, in other words, CCS technologies toward the realization of the carbon neutral society.
CCS is a technology that separates and recovers CO2 emitted from power plants, steel plants, cement plants, and chemical plants, and injects and stores it deep underground.
We are going to keep on making efforts so that our technologies can be utilized toward the realization of the carbon neutral society such as investigation, consideration, and assessment of strata to store an adequate amount of CO2 necessary for the promotion of CCS and the development of monitoring system necessary for the monitoring of stored CO2.
Social Efforts related to society
Technologies to determine the priorities of development of efficient planar route networks
Many road disaster prevention measures are no more than dispersed development and sufficient measures have not been taken for the functions of road networks. However, “planar development” that assumes various disasters and takes composite countermeasures is necessary for securing road networks in the event of a disaster.
The “Infrastructure Technology Institute” of Nippon Engineering Consultants has combined the analysis technologies they have developed such as earthquake resistance, tsunami simulation, slope failure prediction, and robust breakwater and the technologies to assess the priorities of road networks to develop an integrated package of disaster prevention and reduction measures against disasters such as earthquake, tsunami, storm surge, flood, slope failure, active fault, and liquefaction in collaborative research with various institutions like universities. The results will be utilized for considerations toward the efficient road infrastructure development for planar disaster prevention and reduction utilizing the AI and the minimization of disaster risks, and road network development plans to maximize investment effects will be proposed.
Investigation and construction technologies to protect lives from disasters
Water is the source of live. Securing and utilization of necessary water has been an issue for human beings since ancient times. While Japan is rich in water resources, the precipitous geography and vulnerable geology may cause significant damage in the event of disasters like heavy rainfall and earthquakes and have significant impacts on our safety.
Our group has conducted periodic inspections that become a basis for the life prolongation plan and emergency inspections after earthquakes and heavy rainfall on as many as 680 sand control facilities located in the basin of Fuji River in Yamanashi Prefecture.
Moreover, investigations of banks, river channels, and sluiceways by river maintenance and management engineers and river inspectors, and consideration of emergency measures and repair constructions have been conducted in the JV with the Regional Development Association on the rivers within the jurisdiction of the Ministry of Land, Infrastructure, Transport and Tourism, Toyama Office of Rivers and National Highways.
[Disaster prevention and reduction facility planning and management]
Dia Consultants is providing support for disaster prevention and reduction in all situations and phases ranging from field survey to grasp the situation, formulation of disaster prevention measure plans, assumption of various damage and planning and design of countermeasure facilities, to maintenance and management of the facilities after completion against various natural disasters following earthquakes, volcanic eruptions, and heavy rainfall.
Community development in the new era
[Research on the community development in response to the COVID-19 pandemic]
In the JST Strategic Basic Research program (social technology research and development) promoted by Japan Science and Technology Agency (JST) and Research Institute of Science and Technology for Society (RISTEX), a research issue in which the future urban strategy project participates, “Overcoming the vulnerability of society, recovery of social fairness, and urban redesign by social distancing” was adopted.
Through the research issue, Nippon Engineering Consultants is going to assess the impacts of physical social distancing on individuals and society and the vulnerability of urban areas and communities as well as promote policy proposals and method development toward town development responding to the new normal.
[Creation of urban diversity and innovation]
Nippon Engineering Consultants is promoting technology sales to communities, proactive participation in and reception of proposals in response to the “comfortable town you would like to walk around” walkable promotion program formulated by the Ministry of Land, Infrastructure, Transport and Tourism in the “space design” field.
We have associated them with SDGs and initiated the consideration of applicability such as walk environment investigation utilizing a video AI analysis and beacons through joint research with universities.
Human resource development
[Acquisition of a doctoral degree]
Technologies related to the social infrastructure we are engaged in are constantly evolving, so it is essential to get the latest information and utilize it for development. We therefore belong to and visit a variety of societies and associations and are constantly learning along with engineers in the same industry.
In the themes where deep research is required among them, we have entered graduate schools (doctoral course) and submitted papers to acquire doctoral degrees.

[Promotion of diverse workstyles]
Activities of “Womenomics! -Working Nadeshiko Club-”
Nippon Engineering Consultants has established “Nadeshiko Club” composed of only female employees to solve issues toward the goal of developing an environment where a lot of women can keep working in various life stages and lifestyles.
1. Formation of women's networks
Based on the recognition that the number of female employees is still very small, female employees talk about the themes which can be discussed only between women in “Nadeshiko Club”, which is providing opportunities for interactions.
2. Efforts toward formation of environments where people can work comfortably
Against the background where household chores and child rearing remain a great burden on women, they are proposing improvement plans for the company issues which can be found only by women and developing environments where everyone can keep on working.
3. Information transmission of “Nadeshiko Club” activities
Information such as results of various activities is transmitted through internal reports and the intranet, which is providing not only female employees but also male employees with opportunities to think about workstyles.
Information is transmitted proactively not only internally but also to job-hunting students and various industries.
Dia Consultants considers human resources the most precious property and believes a healthy mental and physical condition of employees contributes to the development of the company. Based on the idea centered on human resources, we are promoting the efforts toward the maintenance and improvement of mental and physical health of employees and their family members.
- ・100% of employees who were determined to need a recheck as the result of periodic checkup should be rechecked.
