Shio daifuku is a traditional confectionery which consists of chewy mochi shells filled with creamy or coarse anko red bean paste. Unlike other daifuku varieties, the red bean paste in shio daifuku is lightly salted, which results in an unusual combination of sweet and savory flavors.

They are usually round, and occasionally whole black beans are incorporated in the mochi wrapper. These soft cakes are a staple at many specialized daifuku shops, but they can also be commonly found in many stores and supermarkets throughout the country.
