To have a brief overview of why Japanese names multiplied, we can look back on Japan’s history during its first era. Japanese civilization flourished from different clans which later on united to become a single kingdom. But before that, these clans are at constant war with one another. Every clan is made of people related by blood or a common ancestor. Marriage also plays a vital role in the foundation of a clan. Two different clans can combine their strength and number through an arranged marriage of the other clan leader’s son and daughter.

As time went on, more powerful clans rise into power. One good example is the Yamato clan, who became well accustomed to their neighboring clans and made stronger ties with them. During the Yamato era, their leader chooses a clan name for each joint clan as well as a title, or a kabane. From this clan-naming system, different clan names started to emerge and were carried on up to this day.

In this article, we’ll course you to some of the awesome Japanese last names that are existing in the past and present. Read on!

Final Thoughts About Japanese Last Names

We were able to discuss a short history of how Japanese last names are given. In ancient Japan, the emperor decides on the clan’s family names resulting in numerous last names appearing one after the other. While these names are exclusive to certain groups of families, newer last names still emerged due to clan merging or branching.

As you can observe, common Japanese last names derived their meaning from the surrounding nature or a description of a person or place. Noble and aristocratic families also have surnames that are exclusive to their circle as they have a direct tie to the royal family.
