Are you satisfied with just “viewing environmental data”?

The change of daily climate, the growth of crops, and concerns about the pests and diseases... the cultivation is a series of decisions.
e-kakashi gives you more than viewing environmental data.
By analyzing the data from our sensors in real time, our IoT te chnology gives you updated information not only on the climate, but also on the growth status of your plants, detecting potential problems such as the pests and diseases and finding the best solutions fo r them.


01/ Increase your income with boosting productivity and improving quality.

02/ Lower the risks with the pest and disease forecasting alert.

03/ An user-friendly, power cable free device with an affordable price.



Improve Quality and Harvest Yields

e-kakashi analyzes the collected environmental data based on plant science, and it suggests specific measures to optimize the cultivating environment. This approach already proved to increase productivity and yield. To know actual case studies, visit (Japanese only)

Train Successors and Preserve Techniques

e-kakashi provides support to solve the problems such as an aging workforce and a shortage of successors. You can share ek Recipe (digital crop calendar), environmental data, and work records, and this makes it possible to preserve techniques and shorten a learning period. Furthermore, you can incorporate your experience and intuition into an ek Recipe. What is more, e-kakashi can be used to improve and take over regional cultivating techniques.

A Wide Variety of Forecasting Alerts

e-kakashi provides you with forecasting alerts such as notification of the optimal harvest time and the existence of pests and diseases. This makes you easier to arrange the number of staffs as necessary at the optimal harvest time and to carry out the whole chemical application at the optimal timing.

Environmental Conservation

For instance, you can utilize the necessary water at the necessary timing under the optimal water management based on the scientific evidence. We support the effective use of limited water resources and the reduction of the amount of greenhouse gas. For details, please refer to the column.



Cultivating Navigation

To understand the “Now”, “Then”, and “Future” of your fields from various angles.

e-kakashi Navi is an environmental data browsing app that can be widely used by one or everyone. Not only momentary data value but also daily average, accumulated temperature, solar radiation, and humidity deficit are automatically calculated, so it is easy to grasp the changes in your fields. Also, you can receive the alert from ek Recipe* that you have already set. With the optimal harvest time forecast, you can systematically arrange the resources and staffs, making good use for the optimization of harvest timing. The resources and staffs can be systematically allocated prior to harvest timing. Pest and disease alerts can avoid risks without missing the timing for chemical application. What is more, with e-kakashi Analytics, you can manage the work and growth records of multiple producers along with the environmental data collected from e-kakashi Navi.
*ek Recipe is the electronic crop calendar from e-kakashi services.

Agricultural BI Tool

To analyze data from various angles.

e-kakashi Analytics is an agricultural BI Tool for a team (for managers and for researchers). Environmental data collected from multiple fields*¹ and work records can be uniformly managed. By utilizing component* ² which specializes in each analysis, you can customize a dashboard you want to see, and this contributes to analyze determinants and the efficient guidance on cultivation.
Furthermore, if you keep the results of analysis as knowledge, and set them into ek Recipe, you can lead to the improvement of cultivating techniques.
*1 : This is a unit of a field that is managed in the apps such as e-kakashi Navi and e-kakashi Note.
*2 : This is a standardized function for analysis that e-kakashi offers.

Work Record Tool

To carry out advanced cultivating management.

e-kakashi Note is a task management tool in which you can see w hen and which tasks should be done and can schedule the date in each fie ld. You can also check unfinished tasks in a list. Y ou don’t overlook and do same task multiple times by mistake. And also you can keep the growth rec ords such as the number of stems and leaves. e-kakashi Note assists the adva nced cultivating management. It can be used alone, but it is also recommende d to share with others. With the linkage of e-kakashi Analytics, you can a nalyze “which tasks” has effects on growth and yield and “ how”, linking to environmental data, work records, and growth records. By doing so, supervisor s can give the appropriate cultivating guidance, and the farmers can receive t he optimal cultivating guidance.




Digital Crop Calendar

To use ek Recipe and create my own recipe.

ek Recipe is a digital crop calendar that tells you the cultiva tion points on each growing stage. It is easy to get started by using the pre-set f ree recipes. You can also set your own threshold, which allows you to create you r own recipe.
It can be shared with others. For example, if you set the thres hold based on the crop calendar of its own area or a specific brand, you can c reate the recipe to take over this expertise. By sharing it, you can work toward the improvement of the cultivating techniques in the whole community .

e-kakashi supportsthe sustainable society

Environmental Conservation in Greening

With the verification tests, e-kakashi holds the system for estimating the actual amount of CO₂ absorption.

With the acceleration of global warming, various companies and organizations are promoting the environmentally conscious management, pursuing forestation projects that will help to absorb CO₂ and greening initiatives for their offices, but it is difficult to grasp the actual amount of the CO ₂ absorption in real time. We developed the system for estimating the amount of CO₂ absorption in greening spaces in which our propriety algorithm was combined with meteorological data and environmental data collected by sensors. Furthermore, we conducted the verification tests on this.
We strive to support the initiatives to bring about a decarboni zed society.

Environmental Conservation Through the Effective and Optimal Use of Water Resources

The optimum water management reduces the amount of water use by 20% and the methane emissions by 40% while improving the harvest efficiency by 20%.

Research has shown that rice paddies emit a large amount of the greenhouse gas methane and it accounts for as much as 20% of the amount of the total emission caused by human activity. Furthermore, it is said that the greenhouse effect of methane is up to 72 times greater than an equal amount of CO₂. This methane is emitted by anaerobic bacteria that inhabit rice paddies. If they were left filled with water, the oxygen in the soil will be depleted. Microbes will be activated, thereby increasing methane production. e-kakashi provides forecasting alert for the optimal timing of water management.
This makes it possible to keep down methane production and to make effective and optimal use of water resources.
