Daifuku

Daifukumochi (大福餅^?), or Daifuku (大福^?) (literally "great luck"), is a Japanese confection consisting of a small round mochi (glutinous rice cake) stuffed with sweet filling, most commonly anko, sweetened red bean paste made from azuki beans.
Daifuku comes in many varieties. The most common is white-, pale green-, or pale pink-colored mochi filled with anko.

Daifuku was originally called Harabuto mochi (腹太餅^?) (belly thick rice cake) because of its filling nature.
Later, the name was changed to Daifuku mochi (大腹餅^?) (big belly rice cake).
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.

By the end of the 18th century, Daifuku were gaining popularity and people began eating them toasted. They were also used for gifts in ceremonial occasions.^[2]
