What is it saying?
It looks safe enough.
Yukkuri okaerinasai. Which I think means "Yukkuri/Take it easy welcome home." So maybe "Welcome home and take it easy?"
I dunno. All I can do is read the hiragana. I think it's safe enough though.
Someone keeps removing family_friendly tags, this was one of them, so I'm not sure if it was a mistake/disapproval/troll.
Tag history shows this was never marked family friendly. It does count, though.
Yes, "welcome home easy."
