In post-war Japan, Inoue Yuichi advocated for "avant-garde calligraphy" and combined and catalyzed the creative techniques and concepts of contemporary Western art, becoming a milestone in the development of modern calligraphy in Japan. In the 1960s, Inoue created the unique "frozen ink" technique, which improved traditional ink and wash materials, strengthened the ink traces separated by water and ink gradients, visually highlighting the level and three-dimensionality of the strokes, and achieved the effects of "resting ink" and "flying white". Inoue's theme of the character "Yume" began in 1966, and in meaning, it is linked to the artist's affection for his parents as well as an unrequited love that went nowhere. It can be said that this is the artistic expression that comes closest to Inoue's emotional life in his career. The artwork "Yume" breaks the structure of traditional Chinese calligraphy characters, but retains the scroll mounting of calligraphy. The strokes extend from the middle to the lower right, with turns, pauses, and ending in a dot stroke, filling the picture with a strong sense of rhythm and expressive tension.
