Magnificent Hand Painted Porcelain Japanese Sake Bottle

This is a beautiful signed hand painted sake bottle or vase. It is made of fine porcelain and is either Japanese or Chinese, not sure which, featuring mountains, trees, water, birds and sanpans that wrap around the bottle. It measures 5.75 inches high and 2 and 3/8 inches across. It is in excellent condition, no chips and no cracks. It is signed but I don't know what it says and I have no idea of the age.
