A noted private collection, USA, acquired from the above.Ohaguro (lit. 'black teeth') is the name given in Japan to the custom of blackening one's teeth with a solution of iron filings and vinegar. It was especially popular between the Heian and Edo periods, from the 10th century until the late 19th century, but the opening of the country to Western customs during the Meiji period led to its gradual disappearance. It was a tradition practiced mainly by married women and some men, almost always members of the aristocracy and samurai. In addition to Japanese society's preference for black teeth, it was also considered beneficial to health, as it prevented tooth decay by acting as a dental sealant.Auction comparison: Compare a related wood netsuke of Okame as a mermaid by Shugetsu, also from the Teddy Hahn collection, at Zacke, Fine Netsuke & Sagemono, 29 October 2021, Vienna, lot 167 (sold for 6,067 EUR).13% VAT will be added to the hammer price additional to the buyer’s premium – only for buyers within the EU.
