| Kashiwamochi has such origin, but oak trees do not grow naturally in Osaka metropolitan district and to the west, such as the Shikoku region, so a leaf of Smilacaceae is mostly used as a substitute since Chimaki (a rice dumpling wrapped in bamboo leaves) has originally been used for the Boy's Festival. |
柏餅にはこのような由来があるが、四国地方などの近畿圏以西では、カシワの木が自生しておらず、元々端午の節句には粽を用いる為、サルトリイバラ科（サンキライ）の葉を代用して作られる事が多い。 |
