Yuzuru Hanyu is Japanese, and all Japanese names are in Chinese.
Japanese culture originated from the Tang Dynasty. Their Chinese is the same as ours, but the way of expression is different, such as their Chinese characters.
The pronunciation of Japanese Chinese is also different from that of our Chinese. Japanese Chinese characters generally have two pronunciations: phonics and training, and the pronunciation is divided into two parts: Han and Wu. The training also has voiced and semi-voiced sounds. Long sounds and awkward sounds are equally divided, so there are often several ways to read a Chinese character. This is fine in daily life, but it is a bit troublesome to apply to names. There is often a phenomenon of multiple sounds for one surname, so the Japanese directly use Chinese characters. Name, this is just one way of writing it.
