What is Hakko Anko: A Fermented Sweet Red Bean Paste
Hakko Anko is a fermented sweet red bean paste made by blending cooked azuki beans with rice koji. Unlike typical anko made with added sugar, this fermented sweet red bean paste relies on the natural enzymes in rice koji to convert starches into gentle sugars. As a result, Hakko Anko can be made with no added sugar and still taste sweet and rounded. The process highlights the sweetness that already lives inside the azuki beans while producing a subtler, more complex flavor than standard koshian or tsubuan.
The fermentation process brings clear benefits. Because rice koji breaks down starch slowly, the paste develops layered umami and mild tang. Fermentation can also improve digestibility and alter texture, making the paste silkier when mashed into koshian or chunkier if left as tsubuan. For practical cooking, pressure cooking azuki beans before fermentation helps them soften evenly and reduces polyphenol loss, which preserves flavor.
Culinary uses for hakko anko are versatile. Use it as a filling for mochi or dorayaki, spread it on toast, stir it into yogurt, or shape it into small sweets alongside traditional neriyōkan or mizuyōkan. Because it needs no added sugar, Hakko Anko pairs well with fresh fruit and lightly sweet desserts where you want a refined balance of taste.

Yōkan Varieties in Japanese confectionery (Hakko Anko and Yōkan)
Yōkan is a classic Japanese dessert with a long history. It began as temple food and evolved into a refined confectionery enjoyed across Japan. The three main varieties are neriyōkan, mizuyōkan, and mushiyōkan. Neriyōkan is dense and jelly like. It uses adzuki bean paste, sugar, water, and kanten to set a firm block that slices neatly.
Mizuyōkan is a lighter version. It contains more water and less kanten, so it becomes smoother and less sweet. For this reason, mizuyōkan is often served chilled in summer to refresh the palate. Mushiyōkan is steamed and thickened with wheat flour or arrowroot. It may include additional elements like candied chestnuts for texture and seasonal flavor.
Key Ingredients for Japanese confectionery (Hakko Anko and Yōkan)
Kanten is the common gelling agent in yōkan. It comes from agar seaweed or tengusa seaweed and creates a clear, firm jelly. Adzuki bean paste provides the base flavor. Makers may use smooth koshian or textured tsubuan. Sugar and water balance sweetness and mouthfeel. For seasonal variety, add candied chestnuts or sweet potato.
