I wonder how Japanese names are translated into Chinese.

Although I don't know Japanese, believe me, Japanese hiragana, katakana and pronunciation are all borrowed from ancient China's glyphs and pronunciations, but many borrowed pronunciations are ancient sounds, such as ancient five tones. So it is not surprising that the pronunciation of some words is indeed similar to that of some Chinese characters in modern Chinese. Of course, there are many Chinese characters in Japanese that are completely different from those in modern Chinese.

In addition, there will be cases where several pronunciations correspond to the same Chinese character or the same sound can correspond to several Chinese characters in Japanese, which is similar to the case that Chinese characters have different homophones and homophones.
