From an early age her artistic talents were evident, and as a schoolgirl in 1960 her work was accepted for a regional art competition. She won prizes at the prefecture art exhibition (1962) and the Dai-cho ten exhibition. She served the mandatory apprenticeships and worked as a kimono painter and designer until 1972, before turning to her best-known style painting geisha in splendid kimono costumes and imaginative settings. Some of Haruyo Morita's kimono designs and paintings of Japanese women wearing elaborate traditional kimonos are shown in her film animation Praying for Japan and on her Facebook page.
She is the artist of Twelve-Layer Kimono, a Showa period print with painted designs ink, color, and gold on paper. In her art she was influenced by the style and drama of Kabuki theatre and the Edo period of Japanese culture. In 2017, during the curatorship of the VMFA's Asian expert, Li Jian, Haruyo Morita's Twelve-Layer Kimono, a gift from a private collection, was added to the permanent collection of the Virginia Museum of Fine Arts' extensive Asian holdings .
She relocated to London in 1977 and arranged exhibitions of her work in London, Los Angeles, New York, and Honolulu. In the 21st century she resides on the New South Wales coast at Korora, in Australia, where she says the light and climate are perfect for creating her art.
