The heat is most definitely on. And with the mercury so high, so are the expectations among the wee ones that you haul them off somewhere that little bit different. Here are a few ideas for Tokyo places where you and they might find some respite during the dog days.

Water, preferably lots of it, works a treat at this time of year. There are plenty of pools around town where the kids can get down to some serious frolicking, though many are indoors and don't allow you to enjoy both the sunshine and the water.

Here, the open-air 50-meter swimming pool with a surrounding area for stretching out under the sun is an agreeable spot for a lazy summer day with the kids. Not that this pool especially goes out of its way to be child-friendly: The automatic showers you have to walk through are remarkably effective at scaring the wits out of tiny children.
