1. Although Japanese calligraphy has been deeply influenced by China since the Sui and Tang Dynasties, this influence was temporarily interrupted due to the ups and downs of Sino-Japanese relations. The interruption period is often the turning point of the rise of Japanese national consciousness and the turning point of calligraphy-the N word is omitted here, so it is better to describe it in detail.
2. The biggest and revolutionary change in Japanese calligraphy is that since the Meiji Restoration, Japan has accepted western modern thoughts and artistic trends, and modern calligraphy such as so-called ink-like calligraphy and few-character calligraphy has emerged, which is almost completely different from China's traditional calligraphy concept. If you know something about western modernist art, especially abstract art, it is not difficult to understand their practices.
3. Japanese modernist calligraphy once had a great influence, mainly in the west, because China had frequent wars in modern times and had long been hostile to Japan. You can find your own information about Japanese modernist calligraphy.
4. Of course, in parallel with modernism, there is traditional calligraphy, that is, calligraphy with China characteristics.
Ok, that's all, for reference only.
