Wagashi (Japanese cakes) are an art form in themselves. They are extremely beautiful creations of both ingenuity and observation of nature that only the Japanese could dream up in such a meticulously detailed way. Flowers, petals, foliage and birds are all featured in wagashi from season to season. There are basically three types of wagashi available at Japanese wagashi shops: namagashi (raw, wet cakes) are made of fresh ingredients that do not keep long; han-namagashi (half raw cakes) made of fresh ingredients that are hardened by long cooking, so keep well for a few weeks; and higashi (dry cakes and sweets), which are made from sugar, bean flour or jellies and keep well for a few months. Namagashi and han-namagashi are very dense and sweet, and mostly made of glutinous rice flour, azuki or other bean paste, chestnuts, sweet potatoes and kanten (agar-agar). Higashi are blocks of sugary bean flour and come in many shapes.
