Vintage Japanese Sake Bottle

This is a Vintage Japanese Sake Bottle. This is marked on the bottom with "Made in Japan" and I think this is circa 1930s. This is preloved and vintage, and I think in great condition. There is one mark on the lip and some black spots around the bottle as shown in pictures (which I think is part of the making of the bottle). Measurements: Approximately 6.25" H x 2.5" W
