Exploring Space with Kids in Yokohama: A Visit to Hamagin Space Science Center”

If you’re visiting Yokohama with children and looking for a fun, educational activity, don’t miss the Hamagin Space Science Center (also known as Hamagin Uchuu Kodomo Center). This hands-on science museum is all about space and astronomy — perfect for curious little minds and grown-ups alike!

Located in Isogo Ward, Yokohama, the center features multiple floors of interactive exhibits, real astronaut gear, a planetarium, and even a climbing wall shaped like a rocket! It’s ideal for rainy days too, since it’s almost entirely indoors.
