Osamu Watanabe is a Japanese artist pioneer in sweets decoration. His work is often associated with the Japanese Kawaii movement. His work is inspired by his mother who was a pastry chef and teacher at a confectionery school, and he believes that sweet brings happiness. He uses decorating piping bags and fake cream made of resin in his artwork. He coined the term "fake cream art" as a new category of contemporary art. A wide variety of his work is displayed in permanent collections of museums throughout Japan. Watanabe has also held exhibitions both in Japan and abroad in China, Turkey, Hong Kong, and Indonesia.
