The referenced document at time of its creation was unique. It retained that distinction for a little over 13 years, at which time the French began to develop their own constitution based on ours. It is possible that there now exist a few more documents based on ours, however, I am unable to name any.
It is entirely possible that Japans governing document is very similar, since it authors were not locals.

We can be fortunate in America to be having debates of whether all people deserve medical treatment, where as some countries are forced into debates of whether or not to build a hospital with their scare resources.

I feel the resources and economics of America are what make it so great, and less to do with the constitution being that much better than any other democracy/republic.
