In fact, Japanese names are not random. If they look random when transliterated, it is also due to cultural differences. Many Japanese names also have their own meanings. However, sometimes many people may think that Japanese names are strange. There seems to be no special rules, just like some words put together. Indeed, some people's names are put together with Chinese characters.
The main reason is that Japanese surnames affect their names. In fact, many times their names are quite nice, but their surnames look particularly strange. Because in Japan in the past, ordinary people did not have surnames, but the aristocratic class could have them, and everyone could give themselves a surname according to their own preferences, so sometimes they might choose it based on their work or life circumstances. Come and get it.
Some surnames at that time were slowly passed down, so you may find that some surnames look strange or even random. For example, "big island" sounds like a big island and has no meaning. Most people focus on the surname when choosing names, and are more casual about first names, so if combined in this way, the name will look really random.
Japanese surnames are also written in Chinese characters. Because of the Japanese language, it is difficult for others to know what his name is if it is not written in Chinese characters. After all, Japan has many surnames with the same sound, and they can only be distinguished by Chinese characters. But in fact, there are also many particularly nice names among Japanese names, which you can find if you follow Japanese celebrities.
