Absolutely astounding value for the price. I have a one year old son and he played more here than at any other playground in Tokyo in the week we have been here. The location was perfect, in the same building as the train station, and there was a roof terrace with porch-swings when he needed a calmer space in between energetic play sessions. The fact that we could leave and return to the play space allowed for nursing and roof-terrace breaks. This was probably his favorite day of our whole trip and Kid's US Land is the biggest part of why.
