Great place for kids of all ages. Took my 1.5 year old son. Many things he was too small for but still enough. Cafeteria was a bit crowded but had a reasonable menu.
The Tamarokuto Science Center is a wonderful place for anyone who loves science, space, and hands-on learning. The exhibitions are very interactive and designed for all ages — kids, students, and even adults will enjoy exploring the different zones. The planetarium show is especially impressive, with a huge dome screen and clear explanations in both Japanese and English.
It feels like transported in time to when I was a kid and was discovering science by experiencing it, touching it and sharing. 100% recommended for families, science lovers and curious people. It has a fix exposition, planetarium and several extra activities. Will repeat and try some activities next time.
The counter warned us before we purchase the ticket that everything in this place is in Japanese. It is great for kids! Not really big though. There are many science display, moonwalk simulation, a chemistry lab, and a planetarium that you have to pay extra to get in. Be warned: it is a 1.1 km walk between the nearest bus stop and this science center. But the walk of the neighborhood is fabulous!
I went here with our schools elementary kids. It was an amazing experience and the staff were very nice and accommodating. Even though I was chaperoning, I too had a lot fo fun with the kids and was really impressed by how much there was to explore. The planetarium was really awesome and they even have the planetarium movie available in English! I would highly recommend for families and schools, it's a great, fun place!
