It's good, but I notice that actual banchi and chome numbers are not included in the address results, just the prefecture, city, and ku, cho, son, gun (various districts). Inputting my own postal code correctly returned my prefecture, city, and area.

This means that having someone's postal code is not going to be enough to get down to the finer detals of, say, apartment numbers. You're going to need to know these details to complete the full address.

I'm not complaining, mind you--this is better than the nothing that preceded it, and I can't argue with the price! Thanks for making this available.
