During the full-scale Japanese invasion of China, the damage to China's cultural relics was far-reaching. 1939, the Japanese even replaced the Jin Sinan wooden columns in the first three archways of Yonghe Palace with cement columns, which reduced the brilliance of the archway, and the replaced Nanmu columns were transported to Japan. It is said that several rooms were built in Nagoya, which shows that the Japanese army plundered China's cultural relics.
According to modern statistics, there are 23,000 famous paintings lost overseas, including 1/3 in Japan.
Among the more than 90,000 collections in Tokyo National Museum, there are tens of thousands of China cultural relics, including Liangzhu cultural jade in Neolithic Age, Tang, Song and Yuan porcelain, and porcelain calligraphy and painting in Qing Dynasty. At present, there are 143 cultural relics such as China's national treasure or important cultural property appearing on the museum website (including 1 1 before Han Dynasty, 2 1 in Wei, Jin, Southern and Northern Dynasties, 45 in Song Dynasty, 19 in Yuan Dynasty, 3 1 in Ming Dynasty and/in Qing Dynasty) These include stone monsters in the late Shang Dynasty, bronzes in the Spring and Autumn Period and the Warring States Period, Haijijing in the Tang Dynasty, original calligraphy by Mi Fei, Zhu and Huang Tingjian in the Song Dynasty, and jade and porcelain in the Ming and Qing Dynasties. Only a few cultural relics are marked as donations, and most of them are not marked with their sources. There are Ma Yuan's Crossing the Water in the Cave, Fishing Alone in the Cold River, Kai Liang's Snow Scene, Li Baixing's Song, Six Ancestors Cutting Bamboo, Li Di's Red and White Lotus, etc. In addition, China's cultural treasures are numerous in Japanese museums. Almost all Japanese 1000 public and private museums have China's collections, and the number should be several hundred thousand.
