(1) theoretically advocates "breaking the principle and showing the reality". The so-called "breaking the truth" is to exclude all ideals and describe the "truth" truthfully without any utilitarian purpose. Japanese naturalistic literature opposes fiction, fantasy, affectation and ideal, and emphasizes self-expression and description of nature. Tayama Katai thinks: "It is enough to reproduce life scenes from eyes to mind", and Shimazaki Tōson thinks that writers are journalists embedded in the battlefield of life. Staring at reality and reappearing life is the creative purpose of Japanese naturalism literature. Therefore, even the ugly reality should be reproduced truthfully. Quilt and New Life show their deep animality.
(2) In creative practice, we advocate the creative method of absolute objectivism. Japanese naturalist writers are calm and objective, trying to describe things without any inclination. Tayama Katai's "explicit description" is to objectively show the beauty, ugliness, goodness and evil in life, to be impartial to the beauty and goodness in the eyes of moralists, and to treat the good, evil, beauty and ugliness equally. Therefore, Japanese naturalistic literature does not shy away from being humble and ugly. For example, the descriptions of lust in Tayama Katai's novels and idiots, lunatics and ugly girls in Bai Niao's works are faithfully displayed.
(3) In writing style, writers are required to confess themselves and expose themselves. Japanese naturalist writers tend to pay attention to the themes of life around them and the things they are most familiar with. In particular, it highlights the writer's own spiritual course, inner anguish and animal instinct in the modern cultural transformation. In Shimazaki Tōson's Breaking the Ring, Ugly Song's hesitation and pain for "breaking the ring" is exactly the author's own painful feeling under social repression. The true pursuit of naturalist writers makes them unable to hold all kinds of burdens in their hearts and really "expose" them. Only in this way can they get inner relaxation.
