Toys Kingdom (omochya no ookoku) is a really good area to take the kids to. There are toys galore and it is divided up into different sections for the kids to play in. There are dolls and dollhouses, tabletop and arcade games, computers for kids to muck around with, lots of balls and toys with sliding balls, instruments, a play rail land with heaps of trains, jungle gyms, huge areas with building blocks to play with.

Basically, it has everything a young kid could ever want. It is located in the Tokyo Dome Complex right next to Suidobashi or Korakuen stations.
