Decades of involvement in the popularization of astronomy,

Starting with holding an astronomical observation party for local children,

Constructing a private observatory...

Before I knew it, I have taught thousands of people how to enjoy and learn about astronomy.

Today, thanks to many encounters and support, I am involved in a wide variety of work, including new construction, maintenance, repair, and remodeling of observatories.

The field of astronomy continues to make endless progress like the vastness of the universe.

We are striving every day to be a bearer of that progress, even if only a little.

We will continue to push forward with the further study of technology.

Our philosophy is "Providing Happiness".

From TOMITA, we will convey the “impression,” “curiosity,” and “peace of mind” that you feel when you look at the stars.

And I would be happy if I could happily connect ​.
