On the top floor of the Aeon mall they have this amazing playground for kids in 2nd grade and younger. It has all sorts of inflatable moon bounce kinds of things that keep the young ones entertained for as long as the adults can stand it. It is a pretty fun place to go on a cold winter day. Our younger two could have stayed all day bounding from play area to play area
Here is the info:
500y per hour per child UNLESS you are a member in which case the price is the same but there is no time limit.
Membership is 1000Y BUT if you get a multiple use pass (available in 5 or 10) or one/three month pass then membership is free.
We got a five visit pass for 2000Y with the included membership. For each visit we can us two tickets for each child. (I guess we'll have to pay for one the third time we go.)
They have them all over Japan and apparently, even one in San Fransisco (though I can't find out any info about that one- whacha think sis?)

They have another branch inside the Kyoto Jusco Family Mall, west of the Saiin station on Shijo.
