Bekomochi is a seasonal confection that is made and eaten for the celebration of “Children’s Day”. It is made from rice powder and brown sugar, but lately, you can see green Bekomochi that tansy is mixed in.
It is said that the name “Bekomochi” is derived from “bekko” meaning turtle shell in Japanese, or “beko” meaning cow in a dialect of Tohoku district, but neither theory has been identified. I think both make sense. They express well the various look of the confection.
Incidentally, Bekomochi is available only in part of Tohoku district and Hokkaido.
In other areas, they have Kashiwamochi to celebrate Children’s Day.
