I don't know anything about Japanese coins but my guess is that it is a "small character" version Nagasaki coin similar to the one illustrated at this website:

Following comment received from Luke Roberts, who has an excellent web page on Nagasaki coins - www.history.ucsb.edu/faculty/roberts/coins/Nagasakiexport.html:
Coin is of the "small character" type, and the sub type would be "falling ho" which refers to the low placement of the right character relative to the center square hole. As such it is a common variety worth a couple of dollars. The top gen character with the bump on the top line may just be a casting error but it may be an unknown type. The only way to know the latter is to find an identical one somewhere
