Tenchijin, Inc.

Tenchijin, Inc. is a start-up company that uses space big data to reveal the value of land that no one is aware of yet.

We develop business solutions using high-precision, high-resolution earth observation satellite data and our proprietary land evaluation engine.
We are recognized as a JAXA STARTUP that conducts projects using Japan Aerospace Exploration Agency (JAXA)'s intellectual property and knowledge, was established by JAXA staff and developers with expertise in the agricultural IoT field.

Potential Producing Area
Discovery Project

We are collaborating with Zespri Fresh Produce Japan to explore the cultivation base of Zespri brand kiwifruit in Japan.

We will discover places here in Japan that match Zespri brand varieties while meeting similar climatic conditions and topography to those of New Zealand in the southern hemisphere. This project has also been selected by the Cabinet Office for Advanced Remote Sensing Data Utilization Demonstration Project 2019.

Using "Space Big Data"
to Increase Rice Production

We have formed a business alliance with Shinmei Holdings,co., ltd. and are working towards the production and branding of rice using space big data.

There are concerns about the future supply capacity of Japanese agriculture due to the aging and declining number of producers, and we will make maximum use of space data and the attractiveness of space as an agricultural policy that will lead to increased rice production in the future.

Research to solve social issues
in the livestock industry

In collaboration with Nippon Telegraph and Telephone East Corporation, we are conducting research to solve social issues in the livestock industry.

This project aims to reduce the cost and improve the quality of domestically produced feed by analyzing the optimal growing environment for the grasses used to feed dairy cows from space and providing information on the risks associated with the growing environment and the timing of seed sowing.
Good feed is an important part of delivering good tasting raw milk to consumers.

Optimize Human Civilization by "Space Big Data"
Space has become more accessible.
Satellites can provide information about the temperature of land and sea, the strength of rain and snow, the wind and tides, and information that is invisible to the human eye. We can learn about the mountains, where no one lives, and about the other side of the world.
By analyzing and visualizing this "invisible information" with our proprietary "Tenchijin Compass", we are able to maximize the benefits of the Big Data in the universe while revealing the value of land that no one has yet noticed.
Once we know the true value of the land, the various civilizational activities of humanity will be optimized.
The compass to navigate
your decision-making
Our proprietary "Tenchijin Compass" is an information platform that utilizes space big data. It analyzes and superimposes huge amounts of data that have been accumulated in accordance with the objectives of your business, and leads you to valuable information.
Search for land by overlapping criteria
For example, when considering new crop plots, there are numerous conditions, such as "temperature below 30°C in August, precipitation between 100mm and 150mm in the early spring, etc.". In order to find the best place in a wide area, each condition can be layered on top of each other to search for the best land.
Visualize the risks
In business, not all land that meets all the requirements is a candidate site. Also, weather conditions need to be taken into account. Tenchijin Compass analyzes data from various sources and visualizes the risk profile of a site to help you make decisions.
Data can be generated
without ground-based observation point
The land you're interested in may be more than a few dozen kilometers away from a ground station with a thermometer or rain gauge. Tenchijin Compass can analyze the location with pinpoint accuracy from space and display a time series of data specific to that location.
