“I came to realize that
Earth observation data
should be more useful to society.”

“I came to realize that
Earth observation data
should be more useful to society.”

When I was a child, I saw the film Apollo 13 and was fascinated by the ingenuity and spirit of challenge of people working in space, so I became a JAXA engineer. Through the development of several Earth observation satellites, I came to realize that Earth observation data (smart big data) should be more useful to society, but that it is not yet being utilized to its full potential.

Just as my own feelings have gradually changed from "space as a dream" to "space as useful to society", it can be said that space big data has now become a driver for solving social problems and evolving human life.

As a bridge between technology and society, I would like to work with various people to create an exciting future.


Expert in Earth observation satellites, was stationed at NASA's Goddard Space Flight Centre. Currently doubles as JAXA's technical area lead, responsible for the entire development process of the GPM main satellite for precipitation observation and the Ibuki-2 satellite for greenhouse gas observation. While specializing in project management of large-scale systems, he also creates business ideas while utilizing observation data from satellites he has developed himself.
