Let me tell you this question! Strong, is eager to learn; No.2 lies in imitation and innovation. I know all Japanese characters, hiragana and katakana! Hiragana is matched with ancient Chinese characters (pure Chinese characters are used in some grand formal occasions), and Katakana is used to spell foreign languages. As can be seen from the characters, Japan is very diligent, learning from the characters of neighboring countries and combining them to create a set of its own characters. Up to now, Japan has proposed to continue to advocate "Sinology" as a noble cultural standard! Katakana's dedication to spelling western languages, history, envoys of the Tang Dynasty and so on all reflect their desire to learn ... I will talk about it in detail here. If you are really keen on this issue, I suggest you study the history of Japanese writing, because writing is the epitome of a country's thought and culture.
