But why did they leave it there?
It likely buried itself deep into the ground after it dropped from the bomber and failed to detonate.
It’s likely they didn’t know it was there
Someone was paid to push dirt over a small hole to build a runway not dig for bombs.
Not necessarily, bombs that don’t explode usually land on very soft ground - presumably the hole closed itself on top of the bomb right as it buried itself in.
Foreshadowing.
Hey Mr. Kimura, where should we build our new airport?
Mr. Koizumi, we have a big plot of empty land over here, do you remember why we haven’t built anything there yet?
… No?
… Okay!
bombs are single use, there’s no need to pick it up now
why it was there in the first place? they probably had no idea, or if there was post-war cleanup it went undetected for some reason
no need to pick it up now
I mean…
Free metal! And uh… I guess if you don’t check it (which I assume they just didn’t know it was there) explosion.
