Modern Japanese names (日本人の氏名 nihonjin no shimei) usually consist of a family name (surname), followed by a given name. This order is common in Asian countries, while middle names are not generally used. Japanese names are usually written in Chinese characters (漢字 kanji) in Japanese pronunciation. Japanese family names are extremely varied: according to estimates, there are over 100,000 different surnames in use today in Japan. Common family names in Japan include Satō (佐藤), Suzuki (鈴木) and Takahashi (高橋) (please refer to the table below).

Surnames occur with varying frequency in different regions; for example, the names Chinen (知念), Higa (比嘉), and Shimabukuro (島袋) are common in Okinawa but not in other parts of Japan; this is mainly due to differences between the language and culture of Yamato people and Okinawans. Many Japanese family names derive from features of the rural landscape; for example, Ishikawa (石川) means “stone river,” Yamamoto (山本) means “the base of the mountain,” and Inoue (井上) means “above the well.”

Until the Meiji Period, common Japanese people did not have a family name. Only the nobles, samurai and some merchants and artisans did. At the time, the vast majority of the population were peasants. The new Meiji government made it compulsory for everyone to choose a surname, using only authorised kanji. Up to the Tokugawa period common people would refer to themselves as being from a particular region, or from a particular branch of business. The names taken by Japanese people in the Meiji period were either those already in use among the upper classes, or they were created by local priests or even simply made up. This perhaps explains why there seem to be around 100,000 Japanese family names currently in existence.

The 30 most common Japanese surnames (2010)

On February 13, 1875 (明治8年) it was officially decreed that all Japanese must adopt surnames. An additional decree from March 17, 1876 mandated that spouses must both keep their original family (maiden) names. It was in the year 1898 that Japan returned to the old civil law that obligated wives to adopt their husbands’ family name.
