Japanese family name.

 ■ Looking at the old Japanese ancient documents more than 100 years ago, there is no surname in the names of farmers or merchants. For example, the same as the current family register of the Edo period (1603-1867). It is written what kind of person lived in the village.) Looking at the back, few people have their last name and name written on both sides, and in most cases, there are only names such as Jinbe or Hansuke. Until the end of the Edo period, only warriors or specially allowed people (e.g., subjects or influential people in the village) were able to officially give their last names. Therefore, the general public allows "Cemoji Taito (wearing a sword with a castle)."When I heard "", I thought it was very honorable. This is because there was the following idea. "The warrior is particularly good. It is rude for farmers or merchants to have sex like the warrior." Due to their status as private, agricultural, common, and commercial, the upper and lower relationship clearly existed even in these trivial things. However, even among farmers and businessmen, there was no such thing as a castle at all. For example, let's say that there is a tenant of a landowner with a surname called Aoki called Tarosaku. Then, this person did not have an official surname, but was called Aokinotarosaku by people. In addition, a person named Gohe who lived in a village with a large bridge was called Ohashi Nogohe. 

■ However, it was in 1870 (3rd year of the reign) that it was decided that "any people can add their surnames." However, since it has been a habit for a long time to have a surname, no one dared to give it a surname. Therefore, the government repeatedly issued an order in 1875 (the 8th year of the reign) saying, "All the people must have their surnames." Since then, people have come to think about what last name should be used. Until now, people who had been called Aokinotarosaku or Ohashinogohe made castles such as Aokinotarosaku or Ohashinogohe, and many people who could not even do that often asked village offices and officials to build suitable castles. For example, because there is a pine tree in front of the house, it is named Matsushida, Yamaguchi because it is at the entrance of the mountain, and Tanaka is named after the famous warrior in the past. In addition, there was a village where only fish and vegetables were named. In addition, there are many surnames derived from the names of temples, occupations, and plants, as well as surnames derived from place names. 

■ Currently, according to data on Japanese surnames through computers, there are 101,733 types and 150,930 types of names. In addition, the most common surname is Suzuki, the second place is Satoh, and the third place is Kobayashi. The most common in men's names are "Hiroshi," the second place is "Toshio," and the third place is "Yoshio," and there are 387 types of Chinese characters written by "Yoshio." In the name of a woman, the first place is Yoshiko, the second place is Keiko, and the third place is Kazuko. Looking at the regional distribution of surnames, Sato is said to be many in Tohoku, Hokkaido, and Kanto regions, and Suzuki is widely distributed in Kanto regions. In addition, Takahashi is distributed throughout Chukoku and Shikoku regions in Higashi Japan.
