I'd like to apologise beforehand in case I'm breaking any rules since I'm extremely new to forums but my curiosity is killing me!!

I've been told by students who study Japanese that it's traditional Chinese and I've been told by students who study Chinese that it's Japanese, so I'm also kind of at a loss as to which language this is to begin with
It's carved by who didn't have a good carving skill. Can't recognize a character.
1st one looks a little like 河
2nd one can be 内,丙,雨?
3rd one is a little like 国,团
I have totally no idea what it is.
