Japan doesn't have street names (normally), they number the blocks and houses. Which is a bit confusing, since the numbers of the houses are not necessarily in order either, other than generally assigned clockwise as they're built. So finding an address with out a map or asking someone can be tricky.
It's amusing since it's sort of like a .9 release of city planning that had some scaling issues, where as everyone else started at 1.0 to 2.0 and named their streets, and laid them out on grids. ;-)
