In later years, Shoko mostly presented his works at Teiten (The Japan Art Academy Exhibitions) and Nitten (The Japan Fine Arts Exhibitions), but in 1948 he left Nitten and formed a new organization with several other artists called "Sozo Bijyutsu" (Creation of Art).
その後は帝展・日本美術展覧会で主に作品を発表したが、1948年（昭和23年）に日展を離れ、数名の画家と共に新団体『創造美術』を結成。
