Happy Children's Day! I celebrated by going hiking, which -- since I don't live next to a mountain or drive a car -- involved an hour-long bike ride each way. I may now have calves of steel. On the way back, we stopped at an onsen, which was packed with kids and babies. Watching a bunch of babies happily splashing away in what is basically a giant bathtub is a pretty great way to spend Children's Day, I have say.
