Vintage Japanese Kutani Ware porcelain sake cup (considered Japanese art)

This is a vintage and previously owned Japanese sake cup. It is hand-painted produced in the Ishikawa perfector of Japan and is considered Japanese art. The diameter is two and an 8 inch and it’s height is 1 inch. In I was unable to get an exact age of the peace it’s obviously older and probably early 20th century there’s a few chips around the top edge and it has some outside cracks that do not show all the way through to the inside they look like surface cracks and because of the age have darkened there’s a good possibility. This is even older, but I can guarantee nothing. I’m trying to show the chips and cracks in the picture so please look at the photos.
