Nissho’s canvases started to be dominated by vivid colors in 1966. He began doing a series of indoor paintings using lots of paint and materials, named Studios. He did not yet have a studio for painting, but he may have seen this subject in much the same way as the cow and horse, as essential to his life. In 1968, he started painting a person inside the studio. In that same period, his Wall and Face and Fence and Man paintings included sheets of newspaper or posters pasted onto a wall, symbolizing modern society. These works expressed modern man’s sense of feeling trapped or lonely. Nissho addressed the same theme in Interiors, a work he painted in the year of his death, which depicts a man sitting, holding his knees to his chest, in a small room covered wall-to-wall in newspaper. Interiors can be thought of as Nissho’s most definitive statement as an artist.
