I looked through our materials on Japanese glass companies, and have not found any references to the Hokuyo Glass Co. I also did a search online, and found a few references.

  • This site mentions that Hokuyo Glass Co. manufactured glass floats, and that "Supposedly, this company stopped making floats in the late 70's although they are still found."
  • This site implies that the company is still open, and "Their plant is designated for making “Tsugaru Vidro (Tsugaru Region glassware)” that is a traditional craft in Aomori, Japan. Tsugaru Vidro is very attractive glassware that is made by a unique use of local fine skills." They also provide contact information for the company.
  • This site has photographs of the Hokuyo Glass Manufacturing Company's Blown Glass Factory, Aomori, Japan.

I can't speak to the accuracy of these references, but I hope they lead you to more information!

As a non-profit, cultural institution, The Museum cannot offer appraisal services. If you wish to determine the value of your glass piece, you may want to consult a reliable local antique dealer, or send a photograph of the object to a reputable auction house (see ArtNet’s directory of auction houses worldwide, http://www.artnet.com/auctionhousedirectory/index.aspx).

You can also find appraisers through several professional organizations: The American Society of Appraisers (phone) 1-800-ASA-VALU (online) http://www.appraisers.org; The Appraisers Association of America (phone) 212-889-5404 (online) http://www.appraisersassoc.org; and The International Society of Appraisers (phone) 312-224-2567 (online) http://www.isa-appraisers.org. 

Your local library may have a subscription to Maloney’s Antiques and Collectibles Resource Directory, which provides listings of appraisers by type of collectible.

While the Museum does not provide appraisals, our curatorial staff may be able to help you identify your object. You can contact them through their online form (http://www.cmog.org/glass-questions).
