"Great - Luck" Manju is "Daifuku" in Japanese which is a soft round rice cake filled with sweet red bean paste.
"Salty" but not actually "salty", it's just a little more salt added compared with normal Daifuku.
So don't worry, it's still sweet ! (*^^)v
We have a wide variety of Daifuku.
Why don't you try as many kinds of Daifuku as you can ? (^_-)-☆
