Kashiwamochi

Kashiwamochi (柏餅) is a mochi rice cake filled with sweet bean paste (or, in a real traditional variant, miso) and wrapped in a kashiwa (Japanese oak) leaf, traditionally eaten for Tango no Sekku, the boys’ festival now observed as Children’s Day on May 5. The oak leaf carries specific symbolism: it doesn’t fall from the tree until a new leaf has sprouted to replace it, making it a natural symbol of unbroken family succession. The leaf itself is not eaten, and its orientation signals the filling: rough, veined side out for anko, smooth side out for miso. Kashiwamochi is traditionally more common in eastern Japan; in much of Kansai and further west, chimaki, glutinous rice wrapped in bamboo leaves, is the more traditional Tango no Sekku food instead.
