Asian Porcelain Tea Pot

Another find while out thrift shopping , it is what I always look for ; Asian Art . This teapot is about 8 inch tall and 4 1/2 inch round , has a pretty pink wisteria tree and gold accent ; it is in pristine condition and was within my budget to spend . I am not sure of province but looks Japanese to me , could anyone help to translate writing from the bottom of pot please , I did try to use google image match ; it was no help .
