Atsuo Yokoyama was born and raised in Kanagawa Prefecture in 1989 to a farming family, and was surrounded by nature and living things. He seemed to immerse himself in an imaginary world, writing down the creatures of the imaginary world in his drawings. He began his path towards becoming an artist in his 30s, and began presenting his work on Instagram. He held his first solo exhibition at a rented gallery in Harajuku in November 2019. The following year, in 2020, he held his second solo exhibition, “~We’re Watching You~,” at the same gallery, and in response to the changing world situation caused by the Coronavirus. Influenced by the style of Basquiat and other artists, he combines free-spirited paintings in acrylic paints and pastels with collage and continues to produce and transmit his work under the theme of “expressing the relationship between nature and human society/human spirit,” which is based on his background of growing up with nature.
