Yukiken Snow Eaters Co., Ltd.

We are a construction consultancy firm specializing in snow control measures, which is rarely found in Japan.
Main Image
Our company is a construction consultancy that excels at designing snow protection measures for road construction. We have also dealt with snow control measures for the extension of Shikansen bullet train lines and snow protection measures for overseas railway construction, as well as for high-rise buildings. We possess excellent numerical simulation technology that is effective for snowstorms, avalanches, snow accretion (in warm areas), and other kinds of snow damage. We also develop and sell mobile observation vehicles that are used for snowstorm observation. We use avalanche observation systems (with a microbarometer) and conduct drone observation at avalanche sites, and develop new technologies. 


  • Avalanche study and analysis

    Avalanche study and analysis

    [Product description] We conduct detailed field studies of past avalanche points and dangerous points. The data obtained from our studies and findings form avalanche simulations are used as references when selecting countermeasure facilities, and in developing various standards regarding avalanches.

  • Snow accretion, snowcap, and snow cornice study and analysis

    Snow accretion, snowcap, and snow cornice study and analysis

    [Product description] Snow accretion, snowcaps, and snow cornices are natural phenomena that require sufficient consideration for facilities incidental to roads, and also for all kinds of facilities that influence our daily lives. We conduct observational studies in the field as well as analysis and simulation, and consider how to prevent or mitigate these phenomena.

  • Snow wind tunnel study

    Snow wind tunnel study

    [Product description] We reproduce snowstorms using actual snow particles and mock snow to observe the risks from snowdrifts and visibility failure, and to gauge the extent to which countermeasures are effective.

  • Snow, ice, and weather study and analysis

    Snow, ice, and weather study and analysis

    [Product description] Study and analysis of snow, ice, and weather are necessary in conducting various studies, projects, and businesses, as this provides the most fundamental data for these activities. Analysis is conducted using the data obtained from fixed-point meteorological observations and snow surveys.

  • Numerical simulation

    Numerical simulation

    [Product description] We reproduce air flow, snowstorms, avalanches, and other phenomena through the latest simulation technology to evaluate the risk and effectiveness of various countermeasures.

  • Study and analysis on snowdrifts and visibility failure

    Study and analysis on snowdrifts and visibility failure

    [Product description] We conduct observations on the amount of snow to quantify snowstorm phenomena, linear observations on visibility, meteorological observations, and field studies. The obtained data, simulated results, and past insights are considered in a comprehensive manner to select and recommend appropriate snowstorm countermeasure facilities, such as snow fences and visual guidance facilities.

  • Snow protection facility study and design

    Snow protection facility study and design

    [Product description] Our company prepares preliminary and detailed designs of snow protection facilities based on the findings from our research and analysis. We also design windbreaks and sand drift prevention facilities.

  • New technology development and research

    New technology development and research

    [Product description] We will actively commit ourselves to R&D on new technologies that can be applied to snow and ice. We aim to make a contribution to our era, which is always changing due to such factors as the environment, aging population, and state-to-state disputes. For example, we will focus on developing snow protection facilities that can co-exist with the landscape and environment, and cost-effective snow countermeasures.

  • Snow and weather database

    Snow and weather database

    [Product description] We offering the long-accumulated AMeDAS weather data to companies and organizations in the same or different fields as a service. Users can access this weather information anytime and anywhere via the Internet for use in their business or research.

  • Software planning, development, and production

    Software planning, development, and production

    [Product description] Our company can plan and produce software products according to customer needs using weather information. We will pursue user-friendliness and high quality so that many people can use easily use our products via the Internet and mobile phones. We also try to provide easy-to-maintain products.

[Company strength]
Very few construction consultancy firms in Japan specialize in snow control measures, so our company has become valuable. We were founded in Hokkaido, and we made snowstorm countermeasures into our strength. Our method of conducting field observations before the design process has earned customer trust. We are a technology-based company, so our employees are encouraged to obtain qualifications. We already have 10 certified technicians, and this trend is helping us to enhance our technological capabilities. Our strong technological partnerships with universities have resulted in many joint projects. Our partners have included Hokkaido University, Tohoku University, Nagoya University, Hokkaido University of Science, Chiba University, and Niigata Institute of Technology. We have sent our directors to a number of academic organizations for academic meetings, including the Japanese Society of Snow and Ice, and Japan Society of Snow Engineering. 

[Business description]
Our company offers construction consultancy services specifically relating to snow control. We especially excel at designing snow protection measures for road construction. We recently offered snow control measures for an extension of the Shinkansen bullet train line and snow protection measures for overseas railway construction. There is also an increasing demand for snow protection measures for high-rise buildings.

[Strength of products/technologies]
Our strength lies in numerical simulation technology. We take pride in the fact that we have the best numerical simulation service for snowstorms and avalanches, among other snow kinds of damage. We also developed simulation technology for the snow accretion associated with snowfall in warm areas. We develop and sell mobile observation vehicles for snowstorm observation, and created and published a database using observation data released from the Meteorological Agency. We are also dedicated developing new technologies, such as an avalanche observation system (with a microbarometer) and drone observation of avalanche sites. 

[Representative's message]
Climate change in recent years has resulted in our starting to see snowfall in unexpected places both in Japan and overseas. I feel that the snow protection technology we have accumulated in Hokkaido will increasingly be in demand in other places. Snow control measures seem to be particularly vital for economic development in countries of the former Soviet Union. Our technology will also be useful in protection and moving measures for sand associated with desertification. This feeling has grown stronger after we have had the good fortune to be able to work overseas. I believe that constant improvement is a requirement for a technology-based company like ours. We intend to contribute to society by enhancing our technological capabilities. 

[Company structure for market development/overseas expansion]
There are 5 sales representatives in the operations department under a director in charge of operations, and they try to cultivate new markets. The technology department is involved in consignment business, but they are also cultivating markets from a technology point of view. The overseas operations mentioned above are also dependent on the director who oversees these operations and the technology department. Russia seems to be a promising market for our snow business, so we have recruited Russian workers, and we are trying to promote the globalization of our company. 

[Market share/Ranking]
Our service is the only simulation of its kind in the world that is commercially available.
