Uehara used her cultivation of descriptive power in paintings, creating skillful sculptures, under a theme of combining plants and humans which she was inspired by an idea of Japanese animism which is the belief that natural objects have souls and gods. The facial expression of creatures that she uses as motifs are calm and the audience can sense divine or gentle and strong vitality from the skin which is very sensitive and soft.
