Saitama Municipal Youth Astronomical Museum aka the Saitama Space Museum (Urawa, Saitama City). さいたま市青少年宇宙科学館。Includes information for the planetarium and special exhibitions.
It’s spring break in Japan. It is also end of school year. Traffic tends to increase and queues lengthen, but there are still some hidden gems that evade the chaos. Saitama’s space museum, or officially the Saitama Municipal Youth Astronomical Museum, is one such place. “Astronomical” is the word they use in the official English, i.e. an Astronomy Museum, but it is actually more like a space science museum.
Saitama Space Museum
A great little space museum located on the old grounds of Urawa Reds (Saitama soccer team) at Komaba stadium. If you are looking for somewhere in Saitama, or close to Tokyo, to bring a young child interested in astronomy, this space museum is worth considering.
The Saitama Municipal Youth Astronomical museum is a great place to instill an interest in astronomy in young children. The museum was designed to appeal to children in particular. Moreover, it introduces the basics of physics in ways that children and adults alike can understand.
Furthermore, children can learn about space and science the best way: hands on experiences. Through the various interactive and educational displays, play areas, reading area and even special events available free of charge. There is also a planetarium that costs 510 yen per adult or 200 yen for students aged 4 and up.

It is quite small and you wouldn’t need a lot of time if you aren’t paying into the planetarium as well, but its a nice little spot for kids. Particularly if you want to get in from the rain and / or heat. If the weather suits, make a day (or half a day) of it with a visit to Besshonuma Park, also in Urawa, Saitama City.
Planetarium Information
