Near where I live, there's a kindergarten, and playground where my daughter would often play in. About a year or so ago, an undetonated missile was discovered. It was one of the many bombs dropped on residential areas during firebombing of Tokyo in WWII. The place where it was discovered is right in front of the kindergarten, and very close to the playground. Luckily it was safely extracted away. But kids have been running around that place for decades.
