I saw this exact vase yesterday and thought it looked old - the colour of the glass, crudity of manufacture, etc. I think the label looks new and not what I would expect of vintage Japanese ware. It also looks like it might have been peeled up from one edge. Most old Japanese stuff just seems to say Foreign. I would guess 1930s Chinese and made by a home worker for a larger company, like I believe many of the paperweights were. Did the post-War Japanese glass industry have out workers?
You can all shoot me down now
