Yokan: The Traditional Japanese Sweet Jelly Explained

Introduction – Japan’s Elegant Sweet Block

Yokan (羊羹) is one of the most traditional and elegant wagashi (和菓子). This sweet, jelly-like confection is made from red bean paste, sugar, and agar, creating a smooth, rich texture that has delighted Japanese tea drinkers for centuries. Often shaped into rectangular blocks, yokan is both visually refined and deeply flavorful.

The History of Yokan

Yokan originated in China as a gelatin-based dish made with sheep (yo) broth (kan). When introduced to Japan in the Kamakura period (1185–1333), Buddhist monks replaced animal gelatin with plant-based agar (kanten). Over time, sugar was added, transforming yokan into the sweet jelly we know today.
