I am a new member and having a hard time finding any information on my Sake jug I picked up at an estate sale, looking for some help from the group. Thanks for your time, Jeff L
This is not antique, probably not even vintage. Looks like one of the current ceramic liquor bottles you might buy at any liquor shop in Japan. The small blue writing gives the registration of the business. 白雪 meaning White Snow is the liquor brand. Do an image search for 白雪 酒 and you will see many other products of that company.
There are a lot of Saki jugs or caraffes. At one time the stoneware caraffes were taken back to the liqor store for refills. I have a number of these in various sizes. The one you have is a recent version.
