Agree on the hole. The stamp is in kanji, I think... So japanese it is.I agree with unclemac, looks like it might of served some other purpose before it was a lamp. Looks like the hole were the cord is ran through was done after it was originally made and the cord looks much newer. I don't think a manufacturer or artist would drill a rough hole like that through there stamp, or hallmark.
