Toy Kingdom Game Centre
In Hyogo there’s a kids amusement park called Omocha Oukoku (おもちゃ王国) or Toy Kingdom in English. There are actually 5 of them in Japan, but the Hyogo one is nearest to us.
We’ve been there countless times and it’s a lot of fun. There’s a water park, giant maze castle, go-karts, small roller-coasters, etc, etc all for kids under 10.
They also have a small game centre, and here’s some of the games they have there.
