We will deliver an impressive starry sky experience.
mobile planetarium

If you go through the entrance of the air dome, you will find yourself in a space full of stars.

​You can enjoy the beautiful stars regardless of the city lights or time. We will visit you anywhere, including areas and facilities where it is difficult to see the starry sky. In addition, it is also possible to project automatic projection programs and your favorite images.

​digital planetarium projection

A special projector is used to project the starry sky and outer space. The live commentary by the astronomical staff is attractive.

​Star Watching

These days, the raw starry sky is becoming a precious thing. Another world awaits when you point your telescope at the starry sky. We will taste the stars that can be seen in each season and explain the stars. We will develop an observation event that can only be done by the astronomical entertainment group TOMITA.

We will visit you with a wagon car, an air dome, a projector, and a mobile astronomy car "Galileo".

In addition to "Galileo", refracting telescopes, reflecting telescopes, binoculars, etc. are available according to the plan. We also have a flat planetarium projecting on a screen and a daytime solar observation session using a special telescope.
