Due to the influence of Japanese culture since ancient times, Japanese characters have always had a special position in the eyes of Japanese people.
They are used to writing Chinese characters stroke by stroke, and always remain in awe of Chinese characters.
Whether it's surnames, personal business cards or the cast of TV movies, most of them are written in block letters.
Therefore, it is normal for Shigemitsu Mamoru to sign the Japanese surrender in Chinese.
The Japanese regard Chinese characters as a difficult and lofty subject to learn Mandarin.
Japanese people are cautious in doing things, and regardless of their calligraphy ability, they write Chinese characters very carefully and neatly.
In fact, Japanese passports are signed by individuals, both in English and Chinese characters. Of course Chinese characters are the mainstream.
