Etymology

The English word "tofu" comes from Japanese tōfu (豆腐). The Japanese tofu, in turn, is a borrowing of Chinese 豆腐 (Mandarin: dòufǔ; tou4-fu) 'bean curd, bean ferment'.

The earliest documentation of the word in English is in the 1704 translation of Domingo Fernández Navarrete 's A Collection of Voyages and Travels, that describes how tofu was made. The word towfu also appears in a 1770 letter from the English merchant James Flint to Benjamin Franklin. The term "bean curd(s)" for tofu has been used in the United States since at least 1840.
