Since exhibiting at Art Brut Tachikawa in 2015, Kaoru Iga has been presenting his works annually. He uses various artistic materials such as colored pencils, pastels, and paints, but he particularly enjoys using palette knives. In recent years, he has expanded his repertoire to include both abstract and representational paintings. Alongside his passion for painting, he has also spent two decades learning the cello, and his focused gaze while playing leaves a lasting impression. Though he struggles with conversation, he enjoys engaging with others and is not shy to meet new people.
