signed Japanese vase

yes it is a mystery,, always wanted to know what the japanese script said,, i think is a ginger or tea jar from the turn of the century,, has a pottery makers mark on bottom but cant read it.. Can you tell me what this pot was for and what the writing is,, is beautiful painted gold and blue thicker bamboo paint,, by hand. well am still waiting,, if anyone can read the signature,, would appreciate to know who painted it.
