Yokan, a firm jelly dessert, is a popular type of wagashi (Japanese sweets) typically made from adzuki (red bean) paste, agar, and sugar. This unique yokan is instead made from imo (sweet potatoes), a specialty of Kawagoe City in Saitama. 

To prepare the soil for potato cultivation, Kinoshita Seian uses the traditional fallen-leaf composting method, which has been around for over 300 years. Fallen leaves are combined with fermenting microorganisms and left for two years to turn into compost. The resulting soil is fertile and soft, leading to plump sweet potatoes with a noticeable  natural sweetness.

This recycling-oriented farming method won the Emperor's Cup in the village development category at the Agriculture, Forestry, and Fisheries Festival and is recognized as a Japan Agricultural Heritage.
