Born in Nagano Prefecture in 1984, she graduated from Joshibi University of Art & Design, where she works as a visiting lecturer. She is also a visiting lecturer at Tokyo University of The Arts.
While studying at Joshibi College of Art and Design, her work entitled The Forty-ninth Day was praised for its moving originality. After creating this piece, Komatsu began to concentrate on her career as a professional painter. Starting from copperplate engraving, she has expanded her realm of creation by incorporating materials such as acrylic paint and even Arita ware in recent years.
Komatsu has been highly receptive to the invisible world from her childhood: her early experience of being immersed in nature, surrounded by animals and rich natural landscapes, developed her distinctive view of life and death that all beings were created equal in soul. With an abundance of expressive power, she has presented her works under the theme of 'Divine Spirits'.
A pair of her Arita ware works of guardian lion dogs, Heaven and Earth Komainu, which had been exhibited as part of London's Chelsea Flower Show, became part of the British Museum's collection, and it has been on permanent display. The works of Miwa Komatsu were in the possession of prominent museums and institutions such as World Trade Center, Nagano Prefectural Art Museum, Woodone Museum of Art, Izumo Grand Shrine (Shimane), The official residence of Consulate-General of Japan in Cleveland (Ohio, USA), Walt Disney Japan, just to name a few.
As a contemporary artist, Komatsu has maintained energetic activities including solo shows and live paintings across a spread of countries with the creational principle "The Great Harmonization".
