I saw on one of the antique shows on TV , I believe it was on Antiques Roadshow, one that was similar to yours. Some are quite old but not worth a great deal. I think they have been made for years as tourist items in some part of Japan. If I remember correctly the dolls were made for different types of luck. Each is slightly different according to what type of luck you wished for. The inscription on the bottom could be the maker or it may be what the doll is for. Could say wealth, or love or whatever the person needed. Thats about all I remember.
