At the time of the Tsunayoshi, the 5th shogun of the Tokugawa's , Gintsuba was introduced. The outside of the Gintsuba was made by skin of Uruchi rice flour, filled with red adzuki bean paste inside, and was lightly roasted.⋅ Later in time, when transferred to Edo, the name was changed to Kintsuba from Gintsuba. The word Kin means gold and Gin means silver, so the change was for the better. At the same time, the outside portion of kintsuba also changed from using rice flour to wheat flour.
