Who knows the legend of the origin of Japanese surnames?

The nation with the most surnames in the world is Japanese. According to the Dictionary of Japanese Names published by the Commercial Press in 1981, there were about 7, surnames in Japan at that time, and new surnames appeared every day. It is estimated that by the middle of the 21st century, Japanese surnames will exceed 15,. 15 thousand surnames! More than the population of some small countries. There are more than one billion people in China, but their surnames are only a few hundred, which shows how complicated Japanese surnames are. Why are there so many surnames in Japan? One hundred and twenty years ago, specifically, before the eighth year of Meiji in Japan (1875), Japanese people didn't have their own names like now. At that time, except for the privileged classes such as nobles, warriors and doctors, farmers, businessmen and ordinary artists all had first names but no surnames, and surnames were the privilege of a few people at that time. Toyotomi Hideyoshi, who is famous in Japanese history, only had a first name of Tokichiro without a surname before he became a samurai, and only had a surname of Muxia after he became a samurai. In the eighth year of Meiji, Japan announced the Order that Miao characters must be called, requiring everyone to have their own surname. Suddenly, there was an upsurge of taking surnames all over Japan. At that time, the population had grown to a considerable extent, and everyone wanted to have a distinctive surname, so the surnames in Japan increased greatly and varied. There is another reason for the increase of surnames. Unlike China people and Koreans who also use Chinese characters, Japanese people do not use the same paternal surname for generations, and a large proportion of Japanese people do not use paternal surnames. As a result, of course, the number of surnames is increasing. Japanese surnames are not only numerous, but also complicated in pronunciation and Chinese characters. There are several or even more than a dozen Chinese characters for surnames with the same pronunciation, and the same Chinese characters will have several pronunciations. For example, ささき can be pronounced as the following surnames-Sasaki, Sasaki, Sasaki, Sasaki, Sasaki, Mausoleum, Que and so on. Japanese people whose surname is ごとぅ can write in Chinese characters in the following ways: Goto, Goto, Goto, Wutong, Wutong, Jiangteng, Niutou, Wudao, Houdao and so on. This is the case with Japanese surnames. I don't know how to read some names written in Chinese characters in complex days, and I don't know how to write Chinese characters when I hear the names. No wonder a survey shows that the Japanese exchange as many as 4 million business cards a day, which means that there are 231 groups of people exchanging business cards every second. In Japan, it is very rude to call each other by the wrong name. Therefore, in order to prevent the other party from mispronouncing their own names, most Japanese people indicate the pronunciation of Japanese next to the names written in Chinese characters. The most common Japanese surname is "Sato". It is said that no matter in the school classroom or in a small company, if someone goes to find someone named "Sato", they will probably see several Satos coming out together. There is a joke that if a Grenade is thrown into a crowded crowd during the rush hour in Japan, ten people will be killed, nine of them will be called Sato. According to a survey conducted by a Japanese institution, the top ten most used surnames are: 1. Sato (? .？ ）。 Second, Suzuki (Bao Naimei. Actor). Third, Gao Qiao (a cartoonist studying in the United States). Iv. Ito (? .？ ）。 V. Watanabe (Junichi. Writer). Qi Teng (Long Yi. Unknown creature in backyard). Tanaka (Fang Shu. Writer). Kobayashi (Guangyi. Go player). Nine, Sasaki (Kotaro swordsman). Ten, Yamamoto (56. First-class war criminals). (Japanese characters and occupations that are familiar to everyone are in brackets, and the question mark is that I can't think of a more suitable person at the moment because of my limited level. You must find that among the top ten surnames, there are three with the word "rattan". Japanese surnames with the word "vine" include Kato, Kudo, Goto, Goto and Naito. Why are there so many surnames with the word "vine"? It is said that 1,5 years ago, there was a family named Fujiwara in Japan. This family had great snobbery for a long time, so many families wanted to live as long as Fujiwara. In the eighth year of Meiji, people who had never had a surname in their lives wanted to get some auspicious taste of the word "rattan" when they took their surnames, so "Fujita", "Fujimoto", "Fujii", "Fujiyama", "Fujikawa", "rattan" and "rattan"! (joke) "and so on the surname was born. From here, we can also see one of the ways of thinking when the Japanese first chose their surnames. Japanese surnames can be roughly divided into the following five types: First, the toponymic surnames are the most in Japan, accounting for more than 8% of all surnames in Japan, generally based on the geographical location of residence. For example, Ueno, Tanaka, Hanoi, Uehara, Shibara and Luqian. It is said that there are as many as 1.5 million people surnamed Tanaka, most of whom are from Kyushu. It is said that rice growers lived in huts in rice fields at that time, so they took the surname Tanaka. Second, the name of the merchant who opens a rice shop is Mi Wu, the person who opens an oil shop defines his surname as "delicious" and "delicious", and those who engage in romantic places are called "the prostitute man", and those who raise pigs are called "pig head" and "pig rice". In addition, such surnames include "Wo Wu", "Zhi Wu" and so on. Third, the mix of place names and font sizes. There are "Omiya", "Yoshiokaya", "Three Rivers House" and "Fat House". Fourth, professional "Hattori", "Forging" and "Furuimaru", it is not difficult to know the occupations of their ancestors from these surnames. "Hattori" refers to the weaver, who was originally the minister of clothing and weaving, but gradually evolved into the word "Hattori" (so Shimada Hanzo, a famous Japanese ninja hattori, is a textile worker and a part-time ninja? Or a ninja part-time textile worker? ）。 "Forging" refers to the blacksmith, and "Furuimaru" refers to the fish firewood that makes a living by fishing. Fifth, there are quite a few numerical types in Japanese surnames. This kind of surnames can be divided into two categories, one is regular numerical surnames, such as "one household", "one well", "one cow", "two people", "three spring", "four pine", "five colors", "six guards", "seven heavies", "eight heavies" and "nine ghosts". The other category is "special digital surnames", such as "one inch and six points", "seven five three fields", "one foot and two inches", "December field" and "one two three". The pronunciation field of Chinese characters with digital surnames is very complicated, and "one household" has at least ぃさど (ichido), ぃさのぇ (ichinoe), ぃさのへ (ichinohe
