Since the pronunciations of Fuku (腹) (belly) and Fuku (福) (luck) are the same in Japanese, the name was further changed to Daifuku mochi (大福餅) (great luck rice cake), a bringer of good luck.
Debido a que fuku (腹?) (‘ventre’) e fuku (福?) (‘sorte’) se pronuncian igual en xaponés, o nome cambiou máis adelante a daifuku mochi (大福餅,?, ‘pastel de arroz gran sorte’), propiciatorio da boa sorte.
