The "Shaseiga-ha ('ha' means school in Japanese)" is devided into two sub-schools appeared in the last half of the 18th century, the one of which is called "Maruyama-ha" and the other "Shijo-ha". These two schools are generally assumed not to be different in the sketching style of the nature. However, when we compare and observe the sketchbooks of MARUYAMA, Okyo (the representative of the "Maruyama-ha") and those of MATSUMURA, Keibun (that of the "Shijo-ha"), we can find that between them there exist certain differences in character and aesthetic sensibility.
