Between 1960 and 1964, Nissho produced a series of works in dark tones with the wall playing a thematic role. House is the depiction of a run-down house painted in dark monotones that seems to be blocking the way of the viewer. In Garbage, he paints an oil drum and discarded metal cans in front of a wall. The wall became a theme he also developed in such works as A Human and Alone. It is thought that Nissho was influenced in this type of expression by the works of other painters in his circle at the time in Obihiro, such as Terashima Haruo, and his brother Kanda Kazuaki. One painter who had a particularly strong influence on him was Cho Yang Gyu, evident from Nissho’s scrapbooks and sketchbooks. Through his painting, Nissho may have been trying to reexamine his own status at the periphery of a provincial farming community that was becoming materially prosperous thanks to Japan’s economic growth.
