Born in Yamaguchi, Japan in 1944, Tagami studied philosophy and graduated from Yamaguchi University in 1967. Masakatsu later studied at the Taka Art Institute and in 1973, he started watercolour painting during his stay in Tokyo. In 1974, he began painting oil and copperplate engraving. Tagami is a self-taught artist who developed diversified skills. He uses a variety of materials such as watercolour, copperplate prints, oil paintings, new ink paintings and drawings. Tagami is passionate to draw and paint and has been painting for more than 40 years. Tagami’s home and atelier, which is built in a rural landscape surrounded by fields, is a large Japanese house that was built over 150 years ago. He grows vegetables in the fields and live a quiet life with nature. In many of Tagami’s paintings, landscape in the background depicts a greenish mountainscape with grasses in the foreground. The hometown where Tagami from - Yamaguchi, is known as “Western Kyoto” surrounded by the nature of the mountains that stretches along the way from Ogun to Little Kyoto and Tsuwano. There are animal figures and human in many of his paintings, the proportion of the figures are surreal and the activities that the characters engaged in seem mysterious. Art critic, Boguslaw Mansfeld compared Tagami Masakatsu's works with that of Bosch and Goya, whereby "in a world of stones, sky and naked existence, a shocking and unsettling loneliness is exposed." Masakatsu's works are sincere and soulful, reflecting his thoughts, sentiments and love of nature.
