Japanese names may be written in hiragana or katakana, the Japanese language syllabaries for words of Japanese or foreign origin, respectively. As such, names written in hiragana or katakana are a phonetic rendering and lack meanings that are expressed by names written in the logographic kanji.

Structure

The majority of Japanese people have one surname and one given name, except for the Japanese imperial family, whose members have no surname. The family name precedes the given name. People with mixed Japanese and foreign parentage may have middle names.

Very few names are in use both as surnames and as given names (for example Mayumi (真弓), Izumi (泉), Masuko (益子), or Arata (新)). Therefore, to those familiar with Japanese names, which name is the surname and which is the given name is usually apparent, no matter in which order the names are presented. It is thus unlikely that the two names will be confused, for example, when writing in English while using the family name-given name naming order. However, due to the variety of pronunciations and differences in languages, some common surnames and given names may coincide when Romanized: e.g., Maki (真紀、麻紀、真樹) (given name) and Maki (真木、槇、牧) (surname).

Family names

The term surname or family name can translate into three different Japanese words, myōji (苗字), uji (氏), and sei (姓), which historically had different meanings. Sei (姓) was originally the patrilineal surname which was granted by the emperor as a title of male rank. In the 8th century, eight types of sei were established, but later all surnames except for ason (朝臣) almost disappeared. Uji (氏) was another name used to designate patrilineal clan. Uji and Sei used in the set: e.g., Minamoto no Ason (源朝臣), Taira no Ason (平朝臣), Fujiwara no Ason (藤原朝臣). Uji and sei together are called seishi or shōji (姓氏) and also simply sei. There were relatively few sei of the medieval noble clans, and they trace their lineage either directly to these sei or to the courtiers of these sei. Myōji (苗字) was simply what a family chooses to call itself, as opposed to the sei granted by the emperor. While it was passed on patrilineally in male ancestors including in haku (uncles), one had a certain degree of freedom in changing one's myōji. See also kabane.

According to estimates, there are over 300,000 different surnames in use today in Japan. The three most common family names in Japan are Satō (佐藤), Suzuki (鈴木), and Takahashi (高橋). People in Japan began using surnames during the Muromachi period. Japanese peasants had surnames in the Edo period; however, they could not use them in public.

Most surnames are written with two kanji characters, but some common surnames are written with one or three kanji. Some surnames written with four or five kanji exist, such as Kadenokōji (勘解由小路), but these are rare.

One large category of family names can be categorized as -tō names. The kanji 藤, meaning wisteria, has the on'yomi tō (or, with rendaku, dō). Many Japanese people have surnames that include this kanji as the second character. This is because the Fujiwara clan (藤原家) gave their samurai surnames (myōji) ending with the first character of their name (which can be pronounced either fuji or tō), to denote their status in an era when commoners were not allowed surnames. Examples include Atō, Andō, Itō (although a different final kanji is also common), Udō, Etō, Endō, Gotō, Jitō, Katō, Kitō, Kudō, Kondō, Saitō, Satō, Shindō, Sudō, Naitō, Bitō, and Mutō. As already noted, some of the most common family names are in this list.

Japanese family names usually include characters referring to places and geographic features.

Given names

Given names are called the "name" (名, mei) or "lower name" (下の名前, shita no namae), because, in vertically written Japanese, the given name appears under the family name.

While family names follow relatively consistent rules, given names are much more diverse in pronunciation and characters. While many common names can easily be spelled or pronounced, parents may choose names with unusual characters or pronunciations; the pronunciation of such names generally cannot be inferred from the written form, or vice versa. Unusual pronunciations have become much more common, as the trend has significantly increased in popularity since the 1990s. For example, the popular masculine name 大翔 is traditionally pronounced "Hiroto", but in recent years alternative pronunciations "Haruto", "Yamato", "Taiga", "Sora", "Taito", "Daito", and "Masato" have all entered use.

Male names often end in -rō (郎/朗, "son" or "clear, bright"⁠) (e.g. "Ichirō"), -ta (太, "great, thick" or "first [son]") (e.g. "Kenta"), or -o (男/雄/夫, "man") (e.g. "Teruo" or "Akio"). Male names often also contain ichi (一, "first [son]") (e.g. "Ken'ichi"), kazu (一, "first [son]") (also written with 一, along with several other possible characters; e.g. "Kazuhiro"), ji (二/次, "second [son]" or "next") (e.g. "Jirō"), or dai (大, "great, large") (e.g. "Daichi").

Female names often end in -ko (子, "child") (e.g. "Keiko") or -mi (美, "beauty") (e.g. "Yumi"). Other popular endings for female names include -ka (香/花, "scent, perfume" or "flower"⁠) (e.g. "Reika") and -na (奈/菜, "greens" or "apple tree") (e.g. "Haruna").

Most personal names use one, two, or three kanji. Four-syllable given names are common, especially in eldest sons.

The usage of -ko (子) has changed significantly over the years: prior to the Meiji Restoration (1868), it was reserved for members of the imperial family. Following the restoration, it became popular and was overwhelmingly common in the Taishō and early Shōwa era. The suffix -ko increased in popularity after the mid-20th century.

Around the year 2006, due to the citizenry mimicking naming habits of popular entertainers, the suffix -ko was declining in popularity. At the same time, names of western origin, written in kana, were becoming increasingly popular for naming of girls. By 2004 there was a trend of using hiragana instead of kanji in naming girls.

Molly Hakes said that this may have to do with using hiragana out of cultural pride, since hiragana is Japan's indigenous writing form, or out of not assigning a meaning to a girl's name so that others do not have a particular expectation of her.

Names ending with -ko dropped significantly in popularity in the mid-1980s, but are still given, though much less than in the past. Male names occasionally end with the syllable -ko as in Mako, but very rarely using the kanji 子 (most often, if a male name ends in -ko, it ends in -hiko, using the kanji 彦 meaning "boy"). Common male name endings are -shi and -o; names ending with -shi are often adjectives, e.g., Atsushi, which might mean, for example, "(to be) faithful."

Katakana and hiragana spellings are characteristic of feminine names rather than masculine names, with katakana often used for women's names in the early 20th century due to being easier to read and write.

A single name-forming element, such as hiro ("expansiveness") can be written by more than one kanji (博, 弘, or 浩). Conversely, a particular kanji can have multiple meanings and pronunciations. In some names, Japanese characters phonetically "spell" a name and have no intended meaning behind them. Many Japanese personal names use puns.

Although usually written in kanji, Japanese names have distinct differences from Chinese names through the selection of characters in a name and the pronunciation of them. A Japanese person can distinguish a Japanese name from a Chinese name. Akie Tomozawa said that this was equivalent to how "Europeans can easily tell that the name 'Smith' is English and 'Schmidt' is German or that 'Victor' is English or French and 'Vittorio' is Italian".
