Much custom involved with how to treat the dead. I can’t read hiragana. Found out months later the sign reads:
“If you trash garbage here, you are sentenced to five years’ penal servitude or
pay a fine of ten million yen under the law.
Moushi Hanashiro Family”
There are no signs in Arlington dictating behavior. We were dressed down by grave police for our behavior. The self appointed monitor accused us of being disrespectful. On the contrary, this is how we honor our dead.
